Guiding Principals of Professional Learning Communities Essay

Normally, in a professional learning community also known as a PLC, the educators work together brainstorming ideas, lessons, and activities that will support a plan to be implemented all in hopes of the student’s achievement. A professional learning community can benefit a school’s environment by reinforcing teacher morale and leadership skills. As the school moves forward, every professional in the building must engage with colleagues in the ongoing exploration of three crucial questions that drive the work of those within a professional learning community: †¢ What do we want each student to learn? How will we know when each student has learned it? †¢ How will we respond when a student experiences difficulty in learning? The answer to the third question separates learning communities from traditional schools. A PLC can serve as a support system that motivates teachers to follow a guided plan. Educators who are building a professional learning community recog nize that they must work together to achieve their collective purpose of learning for all. Therefore, they create structures to promote a collaborative culture. This plan can include classroom assistants, parent volunteers, and other school personnel like librarians. The PLC culture can influence teachers through numbers. When teachers come together and have strength in numbers they can support each other, collaborate, and brainstorm the most effective methods and techniques to instruct the students. Even the grandest design eventually translates into hard work. The professional learning community model is a grand design, a powerful new way of working ogether that profoundly affects the practices of schooling. But initiating and sustaining the concept requires hard work. This is where the challenges may arise. It requires the school staff to focus on learning rather than teaching, work collaboratively on matters related to learning, and hold itself accountable for the kind of results that fuel continual improvement. A PLC will construct a solid foundation of committed teachers who are passionate about their career and working with families a nd fellow colleagues. The benefit(s) of a PLC is that everyone has the opportunity to be involved and share goals and positive learning experiences of the schools learning environment. When educators do the hard work necessary to implement these principles, their collective ability to help all students learn will rise. If they fail to demonstrate the discipline to initiate and sustain this work, then their school is unlikely to become more effective, even if those within it claim to be a professional learning community. The rise or fall of the professional learning community concept depends not on the merits of the concept itself, but on the most important element in the improvement of any school; the commitment and persistence of the educators within it. In conclusion, educators who work together form structured atmospheres that promote learning. References Barth, R. (1991). Restructuring schools: Some questions for teachers and principals.

Unity in Diversity

INTRODUCTION One of the greatest leaders that the world has ever seen, Mohandas Karamchand Gandhi, was a political figure, a social and political reformer, a humanist, a visionary and a spiritual leader, who took the country on the road to freedom. Gandhi, popularly known as the Mahatma, not only led the freedom struggle in India but also performed a pivotal role in the struggle of the Indians for civil rights in South Africa. Victimized by incidents of racial discrimination, Gandhi embarked on a crusade against injustice in South Africa that he continued the rest of his life.The twenty long years that Gandhi lived in South Africa, had a considerable influence on the formation of his political ideologies and the philosophies of his life. It was in South Africa that Gandhi's stature gradually began to gain height. His experiences and activities in South Africa provided the necessary background for his subsequent emergence onto the Indian political scenario. His greatest achievement in South Africa was perhaps the unification of the heterogeneous Indian community that comprised of disgruntled merchants and the bonded laborers.The ideological concepts with which Gandhi revolutionized the Indian political scenario were molded to a large extent in South Africa. The celebrated notion of Satyagraha emerged as a consequence of various influences that worked on him. He extensively read religious books on Hinduism, like the BhagwatGita, and Christianity in South Africa. The works of Henry David Thoreau, Leo Tolstoy, John Ruskin and Ralph Waldo, also had significant influences on his thoughts.The notion of non co-operation, as a civilian weapon to fight governmental tyranny was discussed by all these major writers, but it was Gandhi who gave practical shape to the concept. He was the first one to organize Satyagraha struggle in South Africa. For Gandhi the doctrine of Satyagraha entailed passive resistance and commitment to the forces of truth. His second weapon, non viol ence or ahimsa also evolved in South Africa. This cardinal principle of Gandhian philosophy was imbibed from Jainism and Vaishnavism. Gandhi showed to the world how non violence could be used as an ffective political tool to fight the injustices hurled by an oppressive government. For Gandhi, ahimsa entailed self control, swaraj or self rule, and chastity. Alongside, Gandhi embraced a philosophy that disapproved of the norms of Western civilization and conceived of moral reformation of the Indians. Gandhi's Arrival in South Africa Upon returning from England with a degree in law, Gandhi began a legal practice in Mumbai and Rajkot, Gujarat. However, he was unsuccessful to establish a career as a lawyer in both the places.At this point, Gandhi received an offer from the firm Dada Abdulla Seth and Company, to be the legal representative of the firm in South Africa. Gandhi accepted the offer and set sail for a whole new world in April, 1893. In the month of May, 1893, Gandhi reached Dur ban. Accompanied by Dada Abdulla, one of the richest Indian traders in Natal, who also happened to be his employer, he went to visit the Durban Court. The European magistrate at the court instructed Gandhi to remove his turban. He not only disobeyed the commands of the magistrate but issued a protect letter to the press.This was, however, just the lull before the storm. The final provocation took place during his journey to Pretoria from Durban shook the consciousness of the young lawyer to such an extent that he assumed a staunch position against racial prejudice. This incident played a major role in carving out the future course of Gandhi's life. As Gandhi was preparing to return to India, after the completion of his lawsuit, the news of a proposed bill, to be introduced by the Natal Government, reached him. This bill would lead to disenfranchising of the Indians in South Africa.Pleaded by his fellow Indians, Gandhi remained back and took up the issue. Although the bill was passed inspite of Gandhi's attempts, his crusade continued for twenty long years. As part of his struggle, he drafted memorandums, distributed petitions and wrote to the newspapers. His activities in South Africa enabled him to gain an image as the patron of Indian civil rights and an important political leader. In the year 1896, Gandhi returned to India for a period of six months. During this period, he sought to present before the Indians, the pitiful situation f their fellow men in South Africa. However, Gandhi's activities were blown out of proportion by the press in South Africa. When he landed in South Africa, an agitated mob comprising of the whites, attacked him. As the news of this attack, spread rapidly, Joseph Chamberlain, enjoined the prosecution of the assailants. During his second phase of stay in South Africa, Gandhi adopted a simple mode of living, renouncing the lavish standards of living. When the Boer War broke out, Gandhi requested the Indian community, to extend their support to the British.In 1901, Gandhi returned to India but he had to return to appear before Joseph Chamberlain, to plead the Indian case. However, he failed to win over the understanding of Joseph Chamberlain. It was also at this time that Gandhi resolved to lead a celibate life and took to reading Ruskin. Satyagraha in South Africa The first Satyagraha struggle that Gandhi launched in South Africa was against the background of the passage of Asiatic Registration Act by the government of Transvaal in 1907.Realizing that his techniques of prayers and petitions had been rendered ineffectual, the tactic of passive resistance emerged as the new method of opposing. He urged the Indian community to disobey the Act and resort to picketing of the major offices like the permit offices. In 1908, in the month of January, Gandhi and other satyagrahis were jailed. Following this a movement commenced where the satyagrahis began to burn the certificates in a bonfire. In the month of September, Gandhi was arrested for the second time, this time sentenced for two months.The following year, saw Gandhi once again behind the bars for three months. It is pertinent to mention here that Gandhi founded a small colony by the name Tolstoy Farm, where his fellow satyagrahis could lead a bare existence. The Indian women joined the Satyagraha struggle, with the pronouncement of the Supreme Court judgment that annulled all Muslim, Hindu and Zoroastrian marriages. As the women satyagrahis were arrested following their march to Newcastle, several Indian miners, under the guidance of Gandhi, decided to cross over Transvaal border, resorting to non violence means.Even Gandhi's wife Kasturba Gandhi was included among the imprisoned women satyagrahis. In the year 1913, in the month of November, fifty seven children, one hundred and twenty seven women and two thousand and thirty seven men resumed the march. Following the ‘blood and iron' policy adopted by government of South Africa, two Christian men Pearson and C. F Andrews were sent to aid Gandhi. This initiative was taken by Gopal Krishna Gokhale, one of the most prominent Indian politicians. The Viceroy of India, Lord Harginge, criticized the policies of the South African government.Pressurized by London, negotiations commenced between South African Government and Gandhi. In an agreement that was finally arrived upon, certain concessions were made. The 13 taxes imposed on the previously indentured laborers were abolished, marriages performed according to Indian customs received legal acceptance and a domicile certificate, with the thumb impression of the holder, was adequate to permit entrance into South Africa. With a trail of significant achievements behind him, Gandhi finally returned to India in the year 1915, and within a brief span of time became the leader of the Indian Nationalism.Champaran First Satyagraha Gandhi, the exponent of the  Satyagraha  movement, staged his first Satyagraha in Champaran, in Bihar. It was in 1917. The poor peasants, the  indigo  growers, of the district invited Gandhi to go there to see for himself the grievances of the much exploited peasants there. Champaran was on the North-western corner of the  Bihar  Province. The River Gandak flows through this area. The river changed its course from time to time, leaving large lakes along its dried up courses. It was along the banks of these lakes the indigo factories were set up.There were two towns and three thousands villages in Champaran. 98 per cent of the people out of the 2 million lived in villages. And most of them were Hindus. Indigo farming was going on there for almost two centuries. In the beginning, the land was owned by the local people. But the white people from Britain grabbed the land and instead of the traditional sugar cane cultivation, the land grabbers compelled the people to enter into indigo cultivation. The British Indigo planters coerced the poor people to grow indigo on 15 per cent of their land and part with the whole crop for rent.Indigo cultivation was profitable only for the British. The local peasants had only misery and penury and poverty. It was on hearing about this predicament of the poor farmers there that Gandhi decided to go there. He left for Champaran along with a Bihari called Rajkumar Shukla. Babu Rajendra Prasad, who was to become the chairman of the Constituent Assembly for drafting a constitution for the new Republic of India, and who became the first President of the Republic of India, was not there, as he was practicing in the far away Patna as an advocate.He was a special person with lot of interest in public affairs and so Gandhi went straight to his house to find that he was away in  Patna. ————————————————- Champaran, Bihar In Champaran, a district in state of  Bihar, tens of thousands of landless  serfs,  in dentured laborers  and poor farmers were forced to grow  indigo  and other cash crops instead of the food crops which was necessary for their survival. These goods were bought from them at a very low price.Suppressed by the ruthless militias of the landlords (mostly British), they were given measly compensation, leaving them mired in extreme poverty. Now in the throes of a devastating famine, the British levied an oppressive tax which they insisted on increasing in rate. Without food and without money, the situation was growing progressively unlivable and the peasants in  Champaran  revolted against indigo plant cultivation in 1914 (at  Pipra) and 1916(Turkaulia) and  Raj Kumar Shukla  took  Mahatma Gandhi  to  Champaran  and the  Champaran  Satyagraha began.Gandhi arrived in Champaran with a team of  eminent lawyers:  Brajkishore Prasad,  Rajendra Prasad,Anugrah Narayan Sinha  and others including Acharya kripalani. ———â€⠀Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€- Kheda, Gujarat A famine had struck the district and a large part of Gujarat, and virtually destroyed the agrarian economy. The poor peasants had barely enough to feed themselves, but the British government of the  Bombay Presidency  insisted that the farmers not only pay full taxes, but also pay the 23% increase stated to take effect that every year. ———————————————— Gandhi's solution While many civic groups sent petitions and published editorials, Gandhi proposed  satyagraha  Ã¢â‚¬â€œ non-violence, mass  civil disobedience. While it was strictly non-violent, Gandhi was proposing real action, a real revolt that the oppressed peoples of India were dying to undertake.. Gandhi also insisted that neither the protestors in Bihar nor in Gujarat allude to or try to propag ate the concept of  Swaraj, or  Independence. This was not about political freedom, but a revolt against abject tyranny amidst a terrible humanitarian disaster.While accepting participants and help from other parts of India, Gandhi insisted that no other district or province revolt against the Government, and that the  Indian National Congress  not get involved apart from issuing resolutions of support, to prevent the British from giving it cause to use extensive suppressive measures and brand the revolts as treason. In Champaran Gandhi established an  ashram  in Champaran, organizing scores of his veteran supporters and fresh volunteers from the region.He organized a detailed study and survey of the villages, accounting the atrocities and terrible episodes of suffering, including the general state of degenerate living. Building on the confidence of villagers, he began leading the clean-up of villages, building of schools and hospitals and encouraging the village leaders hip to undo purdah, untouchability and the suppression of women. He was joined by many young nationalists from all over India, including  Brajkishore Prasad,Rajendra Prasad,  Anugrah Narayan Sinha, Ram Navami Prasad and  Jawaharlal Nehru.But his main assault came as he was arrested by police on the charge of creating unrest and was ordered to leave the province. Hundreds of thousands of people protested and rallied outside the jail, police stations and courts demanding his release, which the court unwillingly did. Gandhi led organized protests and strike against the landlords, who with the guidance of the British government, signed an agreement granting more compensation and control over farming for the poor farmers of the region, and cancellation of revenue hikes and collection until the famine ended.It was during this agitation, that Gandhi was addressed by the people as  Bapu  (Father) and  Mahatma  (Great Soul). In Kheda In Gujarat, Gandhi was only the spiritual he ad of the struggle. His chief lieutenant,  Sardar Vallabhbhai Patel  and a close coterie of devoted Gandhians, namely  Narhari Parikh,  Mohanlal Pandya  and  Ravi Shankar Vyas  toured the countryside, organized the villagers and gave them political leadership and direction.Many aroused Gujaratis from the cities of  Ahmedabad  and  Vadodara  joined the organizers of the revolt, but Gandhi and Patel resisted the involvement of Indians from other provinces, seeking to keep it a purely Gujarati struggle. Patel and his colleagues organized a major tax revolt, and all the different ethnic and caste communities of Kheda rallied around it. The peasants of Kheda signed a petition calling for the tax for this year to be scrapped in wake of the famine. The government in Bombay rejected the charter.They warned that if the peasants did not pay, the lands and property would be confiscated and many arrested. And once confiscated, they would not be returned even if most compli ed. None of the villages flinched. The tax withheld, the government's collectors and inspectors sent in thugs to seize property and cattle, while the police forfeited the lands and all agrarian property. The farmers did not resist arrest, nor retaliate to the force employed with violence. Instead, they used their cash and valuables to donate to the Gujarat Sabha  which was officially organizing the protest.The revolt was astounding in terms of discipline and unity. Even when all their personal property, land and livelihood were seized, a vast majority of Kheda's farmers remained firmly united in the support of Patel. Gujaratis sympathetic to the revolt in other parts resisted the government machinery, and helped to shelter the relatives and property of the protesting peasants. Those Indians who sought to buy the confiscated lands were ostracized from society. Although nationalists like  Sardul Singh Caveeshar  called for sympathetic revolts in other parts, Gandhi and Patel fir mly rejected the idea.The Government finally sought to foster an honorable agreement for both parties. The tax for the year in question, and the next would be suspended, and the increase in rate reduced, while all confiscated property would be returned. Gujaratis also worked in cohesion to return the confiscated lands to their rightful owners. The ones who had bought the lands seized were influenced to return them, even though the British had officially said it would stand by the buyers Non-Cooperation Movement The  Non-Cooperation Movement  was a significant phase of the  Indian struggle for freedom  from  British rule.This movement lasted from September 1920 to February 1922. It was led byMahatma Gandhi  and was supported by the  Indian National Congress. It aimed to resist British occupation in India through non-violent means. Protestors would refuse to buy British goods, adopt the use of local handicrafts, picket liquor shops, and try to uphold the Indian values of honour and integrity. The  Gandhian  ideals of  Ahimsa  or  non-violence, and his ability to rally hundreds of thousands of common citizens towards the cause of Indian independence, were first seen on a large scale in this movement.Among the significant causes of this movement were colonial oppression, exemplified by the  Rowlatt Act  and  Jallianwala Bagh massacre, economic hardships to the common man due to a large chunk of Indian wealth being exported to Britain, ruin of Indian artisans due to British factory-made goods replacing handmade goods, and popular resentment with the British over Indian soldiers dying in  World War I  while fighting as part of the  British Army– , in battles that otherwise had nothing to do with India.The calls of early political leaders like  Mohammad Ali Jinnah  (who later became communal and hardened his stand),  Annie Besant  and  Bal Gangadhar Tilak  (Congress Extremists) for  rule were accompanied only b y petitions and major public meetings. They never resulted in disorder or obstruction of government services. Partly due to that, the British did not take them very seriously. The non-cooperation movement aimed to ensure that the colonial economic and power structure would be seriously challenged, and British authorities would be forced to take notice of the people's demands. Here we should know that many evolutionaries like Bhagat Singh, Chandra Shekhar Azad were supporters of this very movement but were really dissatisfied by the dismissing of movement by Gandhiji. Civil Disobedience Movement Under the leadership of Gandhiji, the Civil Disobedience Movement was launched in AD 1930. It began with the Dandi March. On 12 March 1930, Gandiji with some of his followers left the Sabarmati Ashram at Ahmedabad and made their way towards Dandi, a village on the west coast of India. After travelling for twenty-five days and covering a distance of three hundred and eighty-five kms, the group reached Dandi on 6 April 1930.Here, Gandhiji protested against the Salt Law (salt was a monopoly of the government and no one was allowed to make salt) by making slat himself and throwing up a challenge to the British government. The Dandi March signified the start of the Civil Disobedience Movement. The movement spread and salt laws were challenged in other parts of the country. Salt became the symbol of people’s defiance of the government. In Tamil Nadu, C Rajagopalchari led a similar march from Trichinopoly to Vedaranyam. In Gujarat, Sarojini Naidu pretested in front of the slat depots.Lakhs of people including a large number of women participated actively in these protests. The Civil Disobedience Movement carried forward the unfinished work of the Non-Cooperation Movement. Practically the whole country became involved in it. Hartals put life at a standstill. There were large-scale boycotts of schools, colleges and offices. Foreign goods were burnt in bonfires. People sto pped paying taxes. In the North-West Frontier Province, the movement was led by Khan Abdul Ghaffar Khan, popularly known as ‘Frontier Gandhi’. For a few days, British control over Peshawar and Sholapur ended.People faced the batons and bullets of the police with supreme courage. No one retaliated or said anything to the police. As reports and photographs of this extraordinary protest began to appear in newspapers across the world, there was a growing tide of support for India’s freedom struggle. The Civil Disobedience Movement led by M K Gandhi, in the year 1930 was an important milestone in the history of Indian Nationalism. There are three distinct phases that mark the development of Indian Nationalism. In the first phase, the ideology of the moderates dominated the political scenario. This was ollowed by the prominence of the extremist ideologies. In the third phase of Indian Nationalism the most significant incident was the rise of MK Gandhi, popularly known as Mahatma Gandhi, to power as the leader of Indian National Movements. Under his spirited guidance, the National Movements of the country took shape. The Indians learnt how apparently philosophical tenets like non violence and passive resistance, could be used to wage political battles. The programs and policies adopted in the movements spearheaded by Gandhi reflected his political ideologies of ahimsa and Satyagraha.While the Non-Co-Operation Movement was built on the lines of non violent non co operation, the essence of The Civil Disobedience Movement was defying of the British laws. Through his leadership to the National Movements, he not only buttressed his political stance but also played a crucial role in unification of the country, awakening of the masses, and bringing politics within the arena of the common man. Factors Leading to the Civil Disobedience Movement The prevalent political and social circumstances played a vital role in the launching of the Civil Disobedience M ovement.The Simon Commission was formed by the British Government that included solely the members of the British Parliament, in November 1927, to draft and formalize a constitution for India. The chairmanship of the commission rested with Sir John Simon, who was a well known lawyer and an English statesman. Accused of being an ‘All-White Commission', the Simon Commission was rejected by all political and social segments of the country. In Bengal, the opposition to the Simon Commission assumed a massive scale, with a hartal being observed in all corners of the province on February 3rd, 1928.On the occasion of Simon's arrival in the city, demonstrations were conducted in Calcutta. In the wake of the boycott of the recommendations proposed by Simon Commission, an All-Party Conference was organized in Bombay in May of 1928. Dr MA Ansari was the president of the conference. Motilal Nehru was given the responsibility to preside over the drafting committee, appointed at the conferen ce to prepare a constitution for India. Barring the Indian Muslims, The Nehru Report was endorsed by all segments of the Indian society.The Indian National Congress pressurized the British government to accept all the parts the Nehru Report, in December 1928. At the Calcutta Session of the Indian National Congress held in December, 1928, the British government was warned that if India was not granted the status of a dominion, a Civil Disobedience Movement would be initiated in the entire country. Lord Irwin, the Governor General, after a few months, declared that the final objective of the constitutional reforms was to grant the status of a dominion to India.Following this declaration, Gandhi along with other national leaders requested the Governor General to adopt a more liberal attitude in solving the constitutional crisis. A demand was made for the release of the political prisoners and for holding the suggested Round Table Conference for reflecting on the problems regarding the constitution of the country. None of the efforts made by the Congress received any favorable response from the British government. The patience of the Indian masses were wearing out. The political intelligentsia of the country was sure that the technique of persuasion would not be effective with the British government.The Congress had no other recourse but to launch the Civil Disobedience Movement. In Bardoli, the peasants had already taken to Satyagraha under the guidance of Sardar Patel in the year 1928. Their non tax agitations were partially successful. The Congress took the decision to use the non violent weapon of Satyagraha on a nation wide scale against the government. The Launch of the Civil Disobedience Movement MK Gandhi was urged by the Congress to render his much needed leadership to the Civil Disobedience Movement.On the historic day of 12th March 1930, Gandhi inaugurated The Civil Disobedience Movement by conducting the historic Dandi Salt March, where he broke the Sa lt Laws imposed by the British Government. Followed by an entourage of seventy nine ashramites, Gandhi embarked on his march from his Sabarmati Ashram to Dandi that is located on the shores of the Arabian Sea. On 6th April 1930, Gandhi with the accompaniment of seventy nine satyagrahis violated the Salt Law by picking up a fistful of salt lying on the sea shore. They manually made salt on the shores of Dandi. Dandi Salt March had an immense impact on the entire nation.Each and every corner of the country was gripped in a unique fervor of nationalism. Soon this act of violation of the Salt Laws assumed an all India character. The entire nation amalgamated under the call of a single man, Mahatma Gandhi. There were reports of satyagrahas and instances of law violation from Bombay, Central and United Provinces, Bengal and Gujarat. The program of the Civil Disobedience Movement incorporated besides the breaking of the Salt Laws, picketing of shops selling foreign goods and liquor, bonfir e of cloth, refusal to pay taxes and avoidance of offices by the public officers and schools by the students.Even the women joined forces against the British. Those from orthodox families did not hesitate to respond to the call of the Mahatma. They took active part in the picketing exercises. Perturbed by the growing popularity of the movement, the British government imprisoned Mahatma Gandhi and Jawaharlal Nehru, in a bid to thwart it. Thus, the second struggle for attaining Swaraj launched by the Congress, under the able guidance of Mahatma, served the critical function of mobilizing the masses on a large scale against the British. Gandhi-Irwin PactIn the March of 1930, Gandhi met with the Viceroy, Lord Irwin and signed an agreement known as the Gandhi-Irwin Pact. The two main clauses of the pact entailed; Congress participation in the Round Table Conference and cessation of The Civil Disobedience Movement. The Government of India released all satyagrahis from prison. Renewal of t he Civil Disobedience Movement Gandhi attended The Second Round Table Conference in London accompanied by Smt. Sarojini Naidu. At this Conference, it was claimed by Mahatma Gandhi that the Congress represented more than eighty five percent of the Indian population.Gandhi's claim was not endorsed by the British and also the Muslim representative. The Second Round Table Conference proved to be futile for the Indians and Gandhi returned to the country without any positive result. The political scene in India thereafter assumed an acute dimension. The Viceroy, Lord Willingdon, in the absence of Gandhi, adopted the policy of repression. The Gandhi-Irwin Pact was violated and the Viceroy took to the suppression of the Congress. The Conservative party, which was in power in England, complied with the decision to assume a repressive stance against the Congress and the Indians.The Congress was held responsible by the government to have instigated the ‘Red Shirts' to participate in The Civil Disobedience Movement, led by Khan Abdul Ghaffar and provoking the cultivators of U. P to refuse to pay land revenue. Adding to this was the serious economic crisis that took hold of the country. Under such circumstances, the resumption of The Civil Disobedience Movement was inevitable. The Congress Working Committee took the decision to restart The Civil Disobedience Movement, as the British government was not prepared to relent.Gandhi resumed the movement in January 1932 and appealed to the entire nation to join in. The Viceroy was also informed of the stance assumed by the Congress. Four ordinances were promulgated by the government to deal with the situation. The police was given the power to arrest any person, even on the basis of mere suspicion. Sardar Patel, the President of Congress and Gandhi were arrested, along with other Congressmen. The second phase of The Civil Disobedience Movement lacked the organization that marked its first phase.Nonetheless the entire nation put up a tough fight and the movement continued for six months. Gandhi commenced his twenty one days of fast on May 8th, 1933, to make amends for the sins committed against the untouchables by the caste Hindus. The Civil Disobedience Movement was suspended, when Mahatma Gandhi withdrew mass Satyagraha on July 14th 1933. The movement ceased completely on April 7th 1934. Although The Civil Disobedience Movement failed to achieve any positive outcome, it was an important juncture in the history of Indian independence. The leadership of Mahatma Gandhi had a beneficial impact.The warring factions within the Congress united under the aegis of The Civil Disobedience Movement, led by Mahatma Gandhi. Satyagraha was put on a firm footing through its large scale usage in the movement. Last but not the least India rediscovered its inherent strength and confidence to crusade against the British for its freedom. Quit India Movement The ascendancy of Mahatma Gandhi in the political scenario of pr e Independence India, bears a close relationship to the roles that he discharged in the three National Movements; namely The Non Co-Operation Movement, The Civil Disobedience Movement and The Quit India Movement.All the three movements were structured following the celebrated political ideologies of Gandhi. Satyagraha or passive civilian resistance and ahimsa or non violence became the unique weapons of Indian National Movements. However, The Quit India Movement departed significantly from the preceding movements in that it lacked organization and widespread violence became a common feature of the movement. Nevertheless, The Quit India Movement occupies a special place in the history of Indian struggle for freedom for taking the final step towards India's independence under the able leadership of Mahatma Gandhi.Gandhi's inspiring statement – â€Å"We shall either free India or die in the attempt; we shall not live to see the perpetuation of our slavery† ignited the sen timents of Indians across the nation. Factors Contributing to the Launch of Quit India Movement In 1939, with the outbreak of war between Germany and Britain, India was announced to be a party to the war for being a constituent component of the British Empire. Following this declaration, the Congress Working Committee at its meeting on 10th October, 1939, passed a resolution condemning the aggressive activities of the Germans.At the same time the resolution also stated that India could not associate herself with war as it was against Fascism. There was hardly any difference between British colonialism and Nazi totalitarianism. Responding to this declaration, the Viceroy issued a statement on October 17th wherein he claimed that Britain is waging a war driven by the motif to strengthen peace in the world. He also stated that after the war, the government would initiate modifications in the Act of 1935, in accordance to the desires of the Indians.Gandhi's reaction to this statement wa s; â€Å"the old policy of divide and rule is to continue. The Congress has asked for bread and it has got stone. † According to the instructions issued by High Command, the Congress ministers were directed to resign immediately. Congress ministers from eight provinces resigned following the instructions. The resignation of the ministers was an occasion of great joy and rejoicing for leader of the Muslim League, Mohammad Ali Jinnah. He called the day of 22nd December, 1939 ‘The Day of Deliverance'. Gandhi urged Jinnah against the celebration of this day, however, it was futile.At the Muslim League Lahore Session held in March 1940, Jinnah declared in his presidential address that the Muslims of the country wanted a separate homeland, Pakistan. In the meanwhile, crucial political events took place in England. Chamberlain was succeeded by Churchill as the Prime Minister and the Conservatives, who assumed power in England, did not have a sympathetic stance towards the clai ms made by the Indians. In order to pacify the Indians in the circumstance of worsening war situation, the Conservatives were forced to concede some of the demands made by the Indians.On August 8th, the Viceroy issued a statement that has come to be referred as the â€Å"August Offer†. However, the Congress rejected the offer followed by the Muslim League. In the context of widespread dissatisfaction that prevailed over the rejection of the demands made by the Congress, Gandhi at the meeting of the Congress Working Committee in Wardha revealed his plan to launch Individual Civil Disobedience. Once again, the weapon of Satyagraha found popular acceptance as the best means to wage a crusade against the British. It was widely used as a mark of protest against the unwavering stance assumed by the British.Vinoba Bhave, a follower of Gandhi, was selected by him to initiate the movement. Anti war speeches ricocheted in all corners of the country, with the satyagrahis earnestly appea ling to the people of the nation not to support the Government in its war endeavors. The consequence of this satyagrahi campaign was the arrest of almost fourteen thousand satyagrahis. On 3rd December, 1941, the Viceroy ordered the acquittal of all the satyagrahis. In Europe the war situation became more critical with the Japanese attack on Pearl Harbor and the Congress realized the necessity for appraising their program.Subsequently, the movement was withdrawn. The Cripps' Mission and its failure also played an important role in Gandhi's call for The Quit India Movement. In order to end the deadlock, the British government on 22nd March, 1942, sent Sir Stafford Cripps to talk terms with the Indian political parties and secure their support in Britain's war efforts. A Draft Declaration of the British Government was presented, which included terms like establishment of Dominion, establishment of a Constituent Assembly and right of the Provinces to make separate constitutions.These wo uld be, however, granted after the cessation of the Second World War. According to the Congress this Declaration only offered India a promise that was to be fulfilled in the future. Commenting on this Gandhi said; â€Å"It is a post dated cheque on a crashing bank. † Other factors that contributed were the threat of Japanese invasion of India, rule of terror in East Bengal and realization of the national leaders of the incapacity of the British to defend their India. Gandhi's Call for Quit India Sir Stafford Cripps left the country amidst unprecedented excitement.Immediately after the return of Sir Stafford Cripps, Gandhi announced ‘Quit India' as the war cry for the Indians. To quote Gandhi, â€Å"The presence of the British in India is an invitation to Japan to invade India. Their withdrawal removes that bait†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦ â€Å". Gandhi realized that the time was ripe to take some strong and quick actions. He wrote a series of articles in Harijan wher e he urged the people to rise in action. He was in favor of resorting to direct action. In order to give effect to the Mahatma's views, The Congress Working Committee adopted the well known ‘Quit India' Resolution, on July 14th 1942 at Wardha.The All India Congress Committee accepted this resolution with some modifications, on 8th August, 1942 in Bombay. The very next day, on 9th August, eminent Congress leaders like Mahatma Gandhi, Vallabhbhai Patel, Jaeaharlal Nehru and Abul Kalam Azad were arrested. The masses were left without any guidance. Gandhi's ‘do or die' call for the people created an upheaval in the country. But at the same time, Gandhi mentioned specifically that mass movement should be conducted following non violent means.The Viceroy, Lord Linlithgow, adopted a policy of harsh repression all over the country and gory instances of British atrocities abounded all over. This ruined the atmosphere of non violence in the country. Unlike the other two movements, the Non-Co-Operation and the Civil Disobedience Movement that unleashed under the aegis of Mahatma Gandhi, the Quit India Movement captures the quintessence of a ‘spontaneous' rising by the people. The Quit India Movement, inaugurated at the call of the Mahatma, unfolded in four phases. In the first phase there were strikes, processions, demonstrations and processions.This phase lasted for a period of three to four days and commenced from the day of Gandhi's arrest on August 9th, 1942. The factory and mill workers rose to the cause and displayed maximum vigor and enthusiasm. The government took recourse to repressive measures to subdue the movement. In an incident of open fire in Bombay, the casualties included large number of women and children. Raids of municipal and government buildings characterized the second phase of the movement. Police stations, post offices and railway stations were attacked and set ablaze.Attempts were made by the agitated mobs to capture court buil dings. Troops fired to control mob fury. September 1942, marks the beginning of the third phase of the movement. It is said that during this phase of the movement, the mob threw bombs on the police in Madhya Pradesh, Bombay and Uttar Pradesh. With the emergence of the movement into the fourth phase, it gained back its peaceful character and extended till Mahatma Gandhi was released from prison in May, 1944. Quit India movement was Gandhi's final bid to secure India's independence.Although, many diverse political ideologies crowded the scenario of Indian National Movement at that time, yet it was the Satyagraha adopted by Gandhi that finally had the most telling effect in challenging the British authorities. India was at the very threshold of Independence by the end of the Quit India movement and Gandhi's long cherished dream was about to be realized. Quit India movement sealed the success for satyagraha as a policy of political resistance, and Gandhi's role as the chief moving force behind India's Independence came to be universally accepted, although dark clouds of a communal fissure still lurked in the background.

The behavioral component means the tendency to take negative actions against a particular group. The behavior stems form attitudes and feelings which constitute prejudice. Although prejudice is generally negative it is not as damaging as discrimination. The behavior component makes it possible to make the thoughts become real. Research has found that discrimination in any form is detrimental to the well being of the discriminated individual (Mathis Jackson, 2004). The workplace is the place in which the employee comes to work on his tasks and to carry out his profession. If the workplace is non-discriminatory, the employee is more likely to work effectively and efficiently and to increase productivity and performance as well. The most common methods employed by organizations to ensure that their work environment is non-discriminatory are to conduct sensitivity trainings, to provide provisions for grievances and complaints of discriminatory behavior and to follow non-discriminatory guidelines in terms of hiring, selection and promotions. Sensitivity trainings are common in most organizations especially if the company is culturally diverse as well as sexual orientation, disability and religion. The advantages of using sensitivity trainings to make employees become aware of the prejudices and discrimination they may have for other people and teaches the employees how to change their thoughts about minority groups in an experiential manner. It also communicates to each employee that an individual is a person in his/her own right and should be respected as such, and not be accorded respect based on one’s race, religion or sex. The disadvantage in using this method is that if  employees do not have a positive attitude towards the training then this would surely limit their capacity to learn from the sessions. Moreover, sensitivity trainings are periodically given and is not reinforced thus limiting its effectiveness. The provisions for grievances and complaints communicate to the employees that discrimination will not be tolerated by the management. It is effective as a control mechanism to lessen discrimination in the workplace and make the employees become cautious of their behavior. This method does not really ensure that the workplace would be discrimination free since it does not teach the employees why discrimination is wrong. It only holds people accountable for their actions, although it gives the employees who belong to the minority group comfort. Besides, discrimination may come in subtle forms and not even many employees who are victims of discrimination will file a complaint for fear of repercussions in terms of inter-office politics. Hiring, selection and promotion of employees based on merit and performance is a non-discriminatory principle to ensure that people become part of the organization based on criteria that can be achieved by most people. The difficulty with this measure is that although it is an objective measure, subjectivity is still present. It is common knowledge that when it comes to promotions and even selecting candidates for the job a certain amount of subjectivity that cannot be monitored by a guideline. It also does not consider that mangers may have their own prejudices which may dictate their decisions on hiring and promotion. References Bohlander, G. Snell, S. (2003).

Utilitarianism Essay Example | Topics and Well Written Essays - 250 words

Utilitarianism - Essay Example When people are accorded this right, they are able to earn money to purchase food, clothing and other basic human goods necessary to make them comfortable hence reducing their suffering through these benefits. If there was no utilitarian ethics here, then people would continue suffering for lack of comfort and benefits. Fairness and justice are also related to utilitarianism in that utilitarianism tries to ensure that actions are not only practical but morally acceptable and will not cause suffering. This is basically what fairness and justice is all about, ensuring that people are comfortable and do not suffer as a result of impracticality of the situation. If utilitarian ethics are upheld and utilized by the society, then unfairness and injustice in issues such as work, school and other important areas of society will be eliminated. People will be ensuring that their actions towards others do not cause any form of suffering and are practical

Organizational Culture Analysis - Research Paper Example It is the hope of this author that such a level of discussion will be beneficial to the reader in terms of helping them to gain a greater understanding, not only the particular store in question, or the retail chain, but the way in which culture is oftentimes represented America. Firstly, with respect to the observable artifacts, it was clear and apparent from day one that the level and type of interaction with the consumer was the primary drive that all of the human resources literature and media consisted of. I distinctly remember the hours of video training that were required prior to even beginning the job in question. For instance, each and every situation that was presented, with the exception of those situations that involved fellow coworkers, was concentric upon maximizing the satisfaction of the consumer and minimizing the difficulties or negative emotions that an employee might represent. In retrospect, it is obvious that all of this was performed as a means of ensuring that profitability remained at a maximum. As the old saying goes, â€Å"the customer is always right†. Ultimately, this particular quote was incorporated within the training literature and served as a backbone with respect to the way in which the employees/stakeholders sought to go about their daily tasks. An espoused value that was promoted heavily within the organization was with respect to the ethical conduct that employees represented. Whereas it is oftentimes the case that individual employers hammer home such issues as the need to come to work on time, the importance and relevance of abstaining from racist, sexist, or ageist language and actions, or the need to give more time and energy to the details of one’s labor, the particular workplace in question had an espoused value system that was almost entirely concentric upon ethics (Baack, 1998). Although it is true that they engaged with the other topics that have been referenced above, the

Computer ethics and law Essay Example | Topics and Well Written Essays - 1250 words

Computer ethics and law - Essay Example To put the discussion into perspective, we’ll use a case study involving a computer professional and a client requiring a personnel management database system. The client chooses the least secure security system from among the list of systems provided. The computer professional clearly clarifies to the customer the security loopholes associated with the system, notable, the risk of unauthorised access to the sensitive personnel information, which might lead to compromise of personnel information by hackers, but the client insists on using it. As Bittner & Hornecker (2002, p. 1) notes, the daily routine of computer professionals provides them with unique opportunities to â€Å"do the right thing† as well as numerous obstacles to achieving this. However, as Norman (1988, p. 2) puts it, the â€Å"...design of technological artefacts should minimise risk and consequences of error.† All professional are obliged to act in such a way as to be worthy of the clientsâ€⠄¢ trust (Bayles 1989) and to ensure social responsibility in all their duties (Durbin 1992). Martin (2011) adds to this by using the words â€Å"pride, honor and self-respect† to describe the ideal conduct of computer professionals. In deciding the way to go, the computer professional in this case study should consider the ethical and professional provisions of the IEEE-CS/ACM Software Engineering Code of Ethics and Professional Practice as it is generally accepted as a standard documentation of software engineers’ ethical and professional requirements and responsibilities. The code has eight principles which Gotterbarn (2000) says are not to be considered as completely exhaustive since there is no way of telling what moral concerns may emerge in the future. They should instead act as a broad framework for professional ethics. Gotterbarn, Miller & Rogerson (1997) reiterate this saying that he IEEE-CS/ACM SECEPP is â€Å"not intended to be all inclusive, nor is it int ended that its individual parts be used in isolation to justify errors of omission or commission†. At the general scale, the IEEE-CS/ACM SECEPP stresses on the engineering profession’s obligation to the public whose health, welfare and safety should take precedence and indeed form the basis of the eight principles of the SECEPP. The â€Å"Public† principle is of particular relevance to our case study. Gotterbarn (1999) argues that computer professionals have substantial chances â€Å"†¦to do good or cause harm† and to aid and influence others to do the same. The principle of Public however requires software engineers to put the public interest first. Not only does this principle hold software engineers responsible for their decisions. In that context, they are required to balance the needs of all the parties (employer, customer, and themselves) with the welfare and safety of the public. This empowers the software engineers to disapprove any software o r component of an IT system that might threaten privacy, degrade the environment, compromise the quality of human life and is especially critical in the manufacture of safety-critical software; computer software whose failure or error can cause directly

Inter Office Memoramdum Essay Example | Topics and Well Written Essays - 750 words

Inter Office Memoramdum - Essay Example In response to your query about the type and effectiveness of an economic policy as a large part of campaign, here I am presenting the following details that will give you an insight about the pros and cons associated with each policy and the basic complementary things associated with each courses of action. In order to have a control over finance, there are two courses of action namely Fiscal Policy and Monetary Policy. These are basically two separate, yet equally important strategies by which we can enact and control our finances and can stabilize economics fluctuation (Iwamoto, 2005, p.3). This came into play mainly after the Great Depression of the 1930’s when it was necessary to regulate how and what was happening financially, how money was being taken in and then later spent, how budgets were enacted, how banks could conduct business, and so forth. Following paragraphs give detail about both Monetary Policy and Fiscal Policy. The process by which the government, central bank, or monetary authority manages the supply of money or trading in foreign exchange markets is referred as Monetary Policy. Monetary Policy is based on the relationship between the rates of interest in an economy, that is the price at which money can be borrowed and the total supply of money. It employs a variety of tools like monetary base, reserve requirements, discount window landing and interest rates to control the price at which money can be borrowed or the total supply of money hence influences the outcomes of economy like economic growth, inflation, exchange rates with other currencies and unemployment.

Sociology of Childhood Essay Example | Topics and Well Written Essays - 1500 words

Sociology of Childhood - Essay Example Browne (2011) defines the term â€Å"life chances† as an individual’s chances of getting access to all those things which are considered as desirable by the society and not being affected by all those things which are considered undesirable by the society. Similarly, in the opinion of Ferrante (2012), social class can be identified as the phenomenon in which an individual’s belonging to a section of society can influence their life chances. Thus, one has to infer that the term â€Å"life chances† indicates having access to at least good education, healthcare facilities, food, clothing and housing. An important point of Marx’s theory of social class is that the bourgeoisies, or the people who own the means of production, enjoy better social standing as they are powerful enough to impose their ideas on the proletariat (the working class). As the bourgeoisie class does not share the wealth justifiably, the difference in wealth between the working class and the bourgeoisie increases. Hence, the working class is deprived of the goods and services enjoyed by the bourgeoisie (Browne 2011). Similarly, Weber categorises the society into two groups; the negatively privileged property class and the positively privileged property class. The positively privileged class is blessed with marketable abilities, and hence is able to enjoy expensive consumer goods and better services. On the other hand, the other class has no marketable abilities, and hence, is deprived of good goods and services (Ferrante 2012). It is pointed out by a UK Government report that measuring child poverty is a difficult task because their life chances are influenced by a number of factors other than just income of the family. Some such dimensions to be included are material deprivation, worklessness, unmanageable debt, poor housing, parental skill level, access to quality education, family stability, and parental health (Secretary of State for Work and Pensions 2012) The Child

Financial analysis Essay Example | Topics and Well Written Essays - 500 words

Financial analysis - Essay Example The current ratios of Merck & Co are ideal, being generally slightly greater than 1. The quick ratio measures whether the firm has enough liquid resources to meet its current liabilities by excluding stock from the current assets in the current ratio (Wood, 1994, p. 418). In this regard, Johnson & Johnson is performing better than its competitors. Its quick ratios for the recent 4 years are slightly greater than 1 while those for its competitors are generally below 1. The debt/equity ratio shows the proportion of long term debt to internal financing. The debt/equity ratios of Johnson & Johnson are at ideally low levels of between 0.05 to 0.11, which are lower than that of the industry average at 0.23. The debt/equity ratios of Procter & Gamble are quite high, ranging from 0.59 to 0.81. However, they are lower than the industry average of 1.01. The debt/equity ratios for Merck & Co., though not as good as those for Johnson & Johnson are reasonable at between 0.27 and 0.33. The leverage ratio shows the amount of assets that a dollar of equity finances. The leverage ratio of Johnson & Johnson at 1.5 to 1.8 are ideal being lower than the industry average of 2.1 and also those of its competitors that range from around 2 to 3. The interest coverage from continuing operations shows the extent to which profit may fall before the firm will not be able to meet its interest charges. When this happens the firm faces being taken over or being wound up. Again, the interest coverage from continuing operations for Johnson & Johnson is excellent. It shoots up from 59 in 2002 to an extremely ideal figure of 253.8 in 2005, especially in light that the industry average is only 27.4. The interest coverage from continuing operations for Procter & Gamble is not as good as that of Johnson & Johnson. It ranges from 12.1 to 14.4 and the data exhibits a downward trend. The interest coverage from continuing operations for Merck & Co also not as good

Lifecycle of a Plastic Product Essay Example for Free

Lifecycle of a Plastic Product Essay Our life has been full with the uses of plastic in our daily life, in food and beverages to the appliances surrounding our daily life. Plastic was made from simple chains of molecules that are linked together called as Polymers. Thus, make many types of plastics are named starting with ‘Poly’ such Polyethylene, polystyrene and polypropylene. Municipal Solid Waste (MSW) More commonly known as rubbish or garbage such as packaging products, grass clippings, furniture, clothing, bottles, food scraps, newspapers, household appliances, paint, these daily items we use then throw away, and battery. It comes from our homes, schools, hospitals, and businesses [2]. Each year, a report on the EPA Advanced Certificate Management Amendment: Facts and Figures 2013, formerly known as Municipal Solid Waste in the United States: Facts and Figures. It contains information on municipal solid waste generation, recycling, and disposal. MSW trace after 30 years, source limit reports (waste prevention) MSW and MSW tipping landfill fees for historical information, generation and demolition Additional information on the information, which has been extended to include outside the scope. The new name emphasizes the importance of sustainable content management (CM). CM refers to the use and recycling of materials in a more productive and durable manner throughout their entire lifecycle. SMM practices to conserve resources reduce waste, slow climate change, the materials we use to reduce their impact on the environment. In 2013, nearly 254 million tons of garbage, recycled and converted to US fertilizer products of 87 million tons, equivalent to 34.3 percent recycling rate was generated. On average, we recycled and 40: 40 pounds per person per day. Even from that, plastic is a very crucial part of our everyday lives, as it been used and basically can be found everywhere. Some examples of usage of plastics are in electronics and surgical instrument as plastic is lightweight, cheap and easy to build. Other than that, plastic is very useful when dealing with durability along with times, it is because plastics don’t easily be damaged by surrounding, unlike iron that can rust over time if in contact with water. Plastic also has a great impact on our today telecommunication, as the world evolves with the technology, a higher demand for internet is needed and fiber optics cable for faster communication with others is needed. The main substances used to produce fiber optic is plastic, in vehicles plastic parts is also one of the major parts needed as it used because it optimizes the power usage and makes them more efficient. The parts that used plastic in a vehicle are including seats, polycarbonate windows and interior panel. Basically, plastic has its own advantages and disadvantages that made it impossible to be ban completely as its usage in every part of daily lives. Even though, it has an important role as one of the vital resources in domestic and also industrial, because of plastics characteristics that are durable, water-resistant, lightweight and cheaper. The usage of plastic needs to supervise and handled appropriately for disposal. Not properly disposing of plastic could lead to plastic pollution due to the basic property of plastic that made it so durable and take thousands of years to decomposed [1]. The overuse of plastic and plastic pollution could give a number of effects on the environment and ecosystem. The effect to the environment is the landfills of plastic wastage due to overuse of plastic because of it cheaper and easier to be obtained. Other than that, an open burning with plastic will release dangerous chemical gasses to the air and could lead to impotence, cancer, asthma and etc. other than that, an authorized disposal of plastics to the sea or river could harm the animals live inside it. From a research, the turtles mostly die because of the plastics that they consume because turtles were mistaken plastics as jellyfish. Besides that, another effect to the animals is the entanglement of plastics to the body of turtles, dolphin and etc. that could affect the animal’s growth. There are several of ways that human can contribute to ensuring a smart usage of plastic to avoid plastic pollution. The easier ways to contribute is by shop friendly when shopping at the market to buy the needs for home, by having oneself shopping bag the usage of plastics can be reduced. Secondly, is to bring your own food container and drink bottle to reduce the usage of plastics from the packaging of your food and plastic bottle that cannot be reusable. Nonetheless, recycling is one of the vital ways that can help in reducing the usage of plastics because by recycling the plastics can be disposed of appropriately.

A Review On Public Switch Data Networks Information Technology Essay

A Review On Public Switch Data Networks Information Technology Essay A public data network is a network established and operated by a telecommunications administration, or a recognized private operating agency, for the specific purpose of providing data transmission services for the public. A public switched data network (PSDN) is a publicly-available packet-switched network, distinct from the PSTN. A general wide area network used to provide circuit switched data services for commercial users A publicly-available network supporting packet-switched data It is an all digital communications line that allows for the transmission of voice, data, video and graphics, at very high speeds, over standard communication lines It is a computer network that uses a public telecommunication infrastructure such as the Internet to provide remote offices or individual users with secure access to their organizations network. It aims to avoid an expensive system of owned or leased lines that can be used by only one organization. A leased line is a service contract between a provider and a customer, whereby the provider agrees to deliver a symmetric telecommunications line connecting two or more locations in exchange for a monthly rent (hence the term lease). It is sometimes known as a Private Circuit or Data Line in the UK. Dial-up Internet access is a form of Internet access that uses the facilities of the public switched telephone network (PSTN) to establish a dialed connection to an Internet service provider (ISP) via telephone lines. The users computer or router uses an attached modem to encode and decode Internet Protocol packets and control information into and from analogue audio frequency signals, respectively. Feature Caller ID, Call Waiting, Voice Mail, and Call Forwarding à ®Ã¢â€š ¬Ã¢â€š ¬Need a connection establishment between end nodes. à ®Ã¢â€š ¬Ã¢â€š ¬Connection is maintained until one of end nodes terminates. à ®Ã¢â€š ¬Ã¢â€š ¬Connection is dedicated to the communication between two nodes. à ®Ã¢â€š ¬Ã¢â€š ¬Reduces the number and the total length of the links Data are transmitted in short messages called packets. à ®Ã¢â€š ¬Ã¢â€š ¬A connection between the two end-nodes is not maintained. à ®Ã¢â€š ¬Ã¢â€š ¬A node-to-node link can be dynamically shared by many packets. à ®Ã¢â€š ¬Ã¢â€š ¬Example : Public Data Network (PDN) likes X.25, Frame Relay. There are two types of PDN: CSPDN and PSPDN. Mostly used to provide leased-line connections between local area networks and the Internet Circuit switch network work by allowing multiple sessions to run between end-user by simply switchingto the most direct or available path Because a circuit switch dedicates bandwidth to each session, it is less effective from packet-switch. The advantage of circuit switch is transparent, and the path is always open, thus the delay through SCPDN is constant, which is ideal for real time application such as video. One of the disadvantage of CSPDN is they are very wasteful of bandwidth, because if the device is not transmitting data, the bandwidth will always be availalbe. Packet switch provide bandwidth on-demand. Advantage of PSPDN is it saved bandwidth, because they only use the bandwidth when there is data to transmit. All data in Packet switching is transmitted in frame/packets over a trunk, where each packet or frame can belong to a different session. All of the data being sent to the network is marked with a sequence number. This mean PSPDN can correct any data corrupt or loss within a network. Disadvantage of PSPDN is buffering. It builds on groups of standard transmission channels. Bearer channels (or B channels) transmit user information at relatively high speeds, while separate Data channels (or D channels) carry call set-up, signaling and other information. It handles all types of information. Unlike some other digital communications technologies, ISDN handles all types of information voice, data, studio-quality sound, still and moving images. They are all digitized, and transmitted at high speeds in the same flow of data. It handles many devices and many telephone numbers, on the same line. It encapsulates data transfers between two or more networked devices which are not on the same private network so as to keep the transferred data private from other devices on one or more intervening local or wide area networks. There are many different classifications, implementations, and uses for VPNs. Typically, leased lines are used by businesses to connect geographically distant offices. Unlike dial-up connections, a leased line is always active. The fee for the connection is a fixed monthly rate. The primary factors affecting the monthly fee are distance between end points and the speed of the circuit. Because the connection doesnt carry anybody elses communications, the carrier can assure a given level of quality. Dial-up connections to the Internet require no infrastructure other than the telephone network. Dial-up is often the only choice available for rural or remote areas where broadband installations are not prevalent due to low population and demand. Dial-up access may also be an alternative for users on limited budgets as it is offered free by some ISPs, though broadband is increasingly available at lower prices in many countries due to market competition. Network Interface Circuit-switched Packet Switching Packet Switching Circuit-switched Packet Switching Device-to-device interfaces are called reference points Interface R Located between Non-ISDN Terminal Equipment (TE2) and a Terminal Adapter (TA) Interface S/T Located between ISDN user equipment and Network Termination (NT1) equipment Interface U Located between NT1 equipment and an ISDN central office RJ45/RJ11 RJ45/RJ11 RJ45/RJ11 Components/ hardware configuration Consists of telephone lines, fiberoptic cables, microwave transmission links, cellular networks, communications satellites, and undersea telephone cables all inter-connected by switching centers which allows any telephone in the world to communicate with any other. In a LAN packet-switched environment, such as with an Ethernet network, the transmission of the data packets relies on packet switches, routers, and LAN cables using permanent virtual circuits (PVCs). Uses TDM (Time Division Multiplexing), SDH (Synchronous Digital Hierarchy) and PDH (Pleisochoronous Digital Hierarchy) Uses Frame Relay and STDM (Statistical Time Division Multiplexing) TE1- Any ISDN-ready device that connects directly to ISDN or connects to ISDN via an NT1. For example: a digital telephone, a GT 70 Series router. TE2- Any non-ISDN device that needs to be used with a Terminal Adapter (TA) to work with ISDN. For example: an analog FAX, PC, or analog telephone. TA-A device that converts non-ISDN communication to ISDN to allow non-ISDN devices to work with ISDN. NT1- A device located between the S/T and U reference points that allows communication between functional devices. Secure VPNs use cryptographic tunneling protocols to provide confidentiality by blocking intercepts and packet sniffing, allowing sender authentication to block identity spoofing, and provide message integrity by preventing message alteration. Leased lines are made up of the following components: a router, usually managed by the service provider, is installed into a customers comms room. The circuit is presented with an RJ45 connector as standard. local loop circuit, , links the router to the service providers local point of presence (POP). Network termination equipment (NTE) is attached to the wall in a comms room and is connected to either a fibre optic or copper local loop circuit. depending upon location, a back haul circuit may be used to link a customer to their service providers point of presence and then onto the internet gateway. This will take place behind the scenes and may run over a third partys national network.
