IOT has had an impact across all fields, be it industries, government, small or large businesses and even for Personal Consumption. What is IOT (Internet of things) you might ask. It’s been a growing topic of conversation for some time now. Put in the simplest term it means anything that has an on and off button and is connected to the internet for receiving, analyzing, storing or sending data. This could mean anything, from the watch that you wear to airplanes that can be controlled from a remote location. According to the analyst firm Gartner, by the year 2020 we’ll have over 26 billion connected devices. That could mean people to people, people connected to things and things connected to things.The new rule of the future is going to be “Anything that can be connected will be connected”. Take for example that when you set an alarm to wake up and that alarm goes off it not only wakes you up but also brews your coffee, sets the right temperature of water for your bath, puts on the television to bring you the latest updates from around the globe and all this before you even put a foot out of your bed. This is all done by simply getting the network of interconnected things/devices that have embedded sensors, network connectivity, software and necessary electronics that collect and exchange data. To show how far we have come with technology and connectivity, we have smartwatches such as Fitbit, Garmin to name a few that have changed the way we look at time. We have one device that not only tells us the time but also tracks the number of steps, calories, and our heart rate. This watch is actually connected to our phone so with just one turn of the wrist, one can tell who is calling or what messages have been received without having to dig through pockets or handbags. IOT is making its presence felt in health care as well. Doctors can now remotely monitor and communicate with their patients and health care providers can benefit from this. Whether data comes from foetal monitors, electrocardiograms, temperature monitors or blood glucose levels, tracking this information is vital for some patients. Many of this requires to follow up interaction with healthcare professionals. With smarter devices that deliver more valuable data, it can reduce the need for direct patient-physician interaction.

Take for instance in the sporting field, minute chips are being attached to balls and bats which will transmit information of how fast the ball is travelling and a batsman’s moves, the time, the angles, the pressure on the bat at different positions, data of the muscle stretch if he’s hit a six so on and so forth. Formula one cars are also being fitted with these sensors which relay information on the minute moves being made by the driver. Chips are also being put into wearable devices of sportsmen to detect suboptimal action of any body parts to show signs of stress or strain which will help in the early detection of injuries and take preventive measures. IOT has had an impact across all fields, be it industries, government, small or large business and even for personal consumption. IBM, Google, Intel, Microsoft, and Cisco are some of the top players in the IOT spectrum. With billions of devices connected security becomes a big issue. How can people make sure that their data is safe and secure? This is one of the major concerns in the IOT that becomes a hot topic. Another issue is with all these billions of devices sharing data companies will be faced with the problem of how to store, track, analyse and make vast sense of the information being generated. Companies are monitoring the network segment to identify anomalous traffic and to take action if necessary. Now that we have a fair understanding of IOT let’s see what impact it’s had on the education sector. The only constant in our lives is change and learning. From the get-go, we learn, be it to the walk, talk or run. We adapt to the changing times and constantly learn from them. Education or learning as we know it in the broader sense is the most important of all and the one that decides which way we handle those changes to impact us and the world. Today’s world is fast-paced and to keep up with this we need an infusion of speed with learning. From the classroom assignments, lectures, blackboards, and chalk we have come a long way to what is now known as e-learning (electronic learning) or m-learning (mobile learning). With the GenNext it is imperative to provide the right kind of education. The rise of technology and IOT allows schools to improve the safety of their campuses, keep track of resources and enhance access to information. It ensures data quality being the top priority but also facilitates the development of content allowing teachers to use this technology to create smart lesson plans and ensuring the reach of this content to any corner of the world.

Technology and IOT have benefited education considerably because it has:

पर्याय

  • Helped in improving the lesson.

  • Helped keep track of all resources.

  • Helped teachers to track.

  • Helped with keeping up with the change in learning.

In Mann Joseph's debut novel Serious Men, the protagonist, Ayyan Mani, is a U1, scheming Dalit-Buddhist who almost gets away with passing off his partially deaf son, Adi, as a prodigy, a genius who can recite the first 1,000 prime numbers. The garb of satire-where almost every character cuts a sorry figure-gives the author the licence to offer one' of the most bleak and pessimistic portrayals of urban Dalits. Despite his savage portrayal of Dalit (and female) characters-or perhaps because of it? Serious Men has won critical appreciation front a cross-section of readers and critics.

At a time when a formidable body of Dalit literature writing by Dalits about Dalit lives has created a distinct space for itself, how and why is it that a novel such as Serious Men, with its gleefully skewed portrayal of an angry Dalit man, manages to win such accolades? In American literature and particularly in the case of African- American authors and characters these issues of representation have been debated for decades. But in India, the sustained refusal to address issues related to caste in everyday life and the continued and unquestioned predominance of a Brahminical stranglehold over cultural production have led us to a place where non-Dalit portrayal of Dalits in literature, cinema and art remains the norm. The journey of modem Dalit literature has been a difficult one. But even though it has not necessarily enjoyed the support of numbers, we must engage with what Dalits are writing not simply for reasons of authenticity, or as a concession to identity politics, but simply because of the aesthetic value of this body of writing, and for the insights it offers into the human condition. In a society that is still largely unwilling to recognise Dalits as equal, rights bearing human beings, in a society that is inherently indifferent to the everyday violence against Dalits, in a society unwilling to share social and cultural resources equitably with Dalits unless mandated by law (as seen in the anti-reservation discourse), Dalit literature has the potential to humanise non- Dalits and sensitise them to a world into which they have no insight. But before we can understand what Dalit literature is seeking to accomplish, we need first to come to terms with the stranglehold of non-Dalit representations of Dalits.

Rohinton Miary's (A Fine Balance), published 15 years ago, chronicles the travails of two Dalit characters uncle Ishvar and nephew Omprakash who migrate to Bombay and yet cannot escape brutality. While the present of the novel is set at the time of the Emergency, Ishvar's father Dukhy belongs to the era of the anti-colonial nationalist movement. During one of Dukhi's visits to the town, he chances upon a meeting of the Indian National Congress, where speakers spread the "Mahatma's message regarding the freedom struggle, the struggle for justice," and wiping out "the disease of untouchability; ravaging us for centuries, denying dignity to our fellow human beings."

Neither in the 1940s, where the novel's past is set nor in the Emergency period of the 1970swhen the minds and bodies Ishvar and Omprakash, are savaged by the state-do we find any mention of a figure like BR Ambedkar or of Dalit movements. In his 'nationalist' understanding of modem Indian history, Mistry seems to have not veered too far from the road charted by predecessors like Mulk Raj Anand and Premchand. Sixty years after Premchand, Mistry's literary imagination seems stuck in the empathy realism mode, trapping Dalits in abjection. Mistry happily continues the broad stereotype of the Dalit as a passive sufferer, without consciousness of caste politics.

Which of the following is not among the reasons suggested by the writer for engaging with Dalit writing:


If religion and community are associated with global violence in the trends of many people, then so are global poverty and inequality. There has, in fact, been an increasing tendency in recent years to justify policies of poverty removal on the ground that this is the surest way to prevent political strife and turmoil. Basing public policy - international as well as domestic- on such an understanding has some evident attractions. Given the public anxiety about wars and disorders in the rich countries in the world, the indirect justification of poverty removal -not for its own sake but for the sake of peace and quiet in the world - provides an argument that appeals to self-interest for helping the needy. It presents an argument for allocating more resources on poverty removal because of its presumed political, rather than moral, relevance.

While the temptation to go in that direction is easy to understand, it is a perilous route to take even for a worthy cause. Part of the difficulty lies in the possibility that if wrong, economic reductionism would not only impair our understanding of the world but would also tend to undermine the declared rationale of the public commitment to remove poverty. This is a particularly serious concern, since poverty and massive inequality are terrible enough in themselves, and deserve priority even if there were no connection whatsoever with violence. Just as virtue is its own reward, poverty is at least its own penalty. This is not to deny that poverty and inequality can - and do - have far-reaching consequences with conflict and strife, but these connections have to be examined and investigated with appropriate care and empirical scrutiny, rather than being casually invoked with unreasoned rapidity in support of a `good cause."

Destitution can, of course, produce provocation for defying established laws and rules. But it need not give people the initiative, courage, and actual ability to do anything very violent. Destitution can be accompanied not only by economic debility but also by political helplessness. A starving wretch can be too frail and too dejected to fight and battle, and even te protest and holler. It is thus not surprising that often enough intense and widespread suffering and misery have been accompanied by unusual peace and silence.

Indeed, many famines have occurred without there being much political rebellion or civil strife or intergroup warfare. For example, the famine years in the 1840s in Ireland were among the most peaceful, and there was little attempt by the hungry masses to intervene even as ship after ship sailed down the river Shannon with rich food. Looking elsewhere, my own childhood memories in Calcutta during the Bengal famine of 1943 include the sight of starving people dying in front of sweetshops with various layers of luscious food displayed behind the glass windows, without a single glass being broken, or law or order being disrupted.

Which of the following statement is least likely to be inferred from the passage:


Paragraph: At this stage of civilisation, when many nations are brought in to close and vital contact for good and evil, it is essential, as never before, that their gross ignorance of one another should be diminished, that they should begin to understand a little of one another's historical experience and resulting mentality. It is the fault of the English to expect the people of other countries to react as they do, to political and international situations. Our genuine goodwill and good intentions are often brought to nothing because we expect other people to be like us. This would be corrected if we knew the history, not necessarily in detail but in broad outlines, of the social and political conditions which have given to each nation its present character.

The character of a nation is the result of its...


Paragraph: In response to the increasing environmental damage wrought by poachers, authorities placed a ban on ivory in the 1980s. Although the ban resulted in an initial decrease in the sale and trade of illegal ivory and a concurrent increase in the elephant population, more pressing needs caused most Western nations to withdraw funding for poaching prevention programs. Without significant financial support, poorer countries were unable to effectively combat poachers. The resulting explosion in the ivory trade has seen prices increase to nearly 10 times the $45 per pound price at the beginning of the decade.

Unfortunately, the countries with the worst poaching problems have also tended to be the ones least able to combat the problem due to unstable political systems, corruption, lack of comprehensive enforcement programs, or some combination of all these factors. One primary hindrance to better enforcement of the ivory ban came from an inability to definitively identify the country of origin of illegal ivory. 

Countries used this uncertainty to avoid responsibility for curbing illegal poaching in their territories by attempting to blame other countries for the oversights in enforcement. Now, though, zoologists have perfected a new DNA identification system. First, scientists gathered genetic data from the population of African elephants, an arduous effort that ultimately resulted in a detailed DNA-based map of the distribution of African elephants. Then, the researchers developed a method to extract DNA evidence from ivory, allowing them to match the ivory with elephant populations on the map. Zoologists hope this new method will pinpoint the exact origin of poached ivory and force countries to accept their responsibility in enforcing the ban.

The passage suggests which of the following about the DNA-based map created by zoologists?


Paragraph: I felt the wall of the tunnel shiver. The master alarm squealed through my earphones. Almost simultaneously, Jack yelled down to me that there was a warning light on. Fleeting but spectacular sights snapped into and out of view, the snow, the shower of debris, the moon, looming close and big, the dazzling sunshine for once unfiltered by layers of air. The last twelve hours before re-entry were particular bone-chilling. During this period, I had to go up into command module. Even after the fiery re-entry splashing down in 81o water in south pacific, we could still see our frosty breath inside the command module.

Which one of the following reasons would one consider as more as possible for the warning lights to be on?


Paragraph: Many great inventions are initially greeted with ridicule and disbelief. The invention of the airplane was no exception. Although many people who heard about the first powered flight on December 17, 1903 were excited and impressed, others reacted with peals of laughter. The idea of flying an aircraft was repulsive to some people. Such people called Wilbur and Orville Wright, the inventors of the first flying machine, impulsive fools. Negative reactions, however, did not stop the Wrights. Impelled by their desire to succeed, they continued their experiments in aviation.

Orville and Wilbur Wright had always had a compelling interest in aeronautics and mechanics. As young boys they earned money by making and selling kites and mechanical toys. Later, they designed a newspaper-folding machine, built a printing press, and operated a bicycle-repair shop. In 1896, when they read about the death of Otto Lilienthal, the brothers' interest in flight grew into a compulsion.

Lilienthal, a pioneer in hang-gliding, had controlled his gliders by shifting his body in the desired direction. This idea was repellent to the Wright brothers, however, and they searched for more efficient methods to control the balance of airborne vehicles. In 1900 and 1901, the Wrights tested numerous gliders and developed control techniques. The brothers' inability to obtain enough lift power for the gliders almost led them to abandon their efforts.

After further study, the Wright brothers concluded that the published tables of air pressure on curved surfaces must be wrong. They set up a wind tunnel and began a series of experiments with model wings. Because of their efforts, the old tables were repealed in time and replaced by the first reliable figures for air pressure on curved surfaces. This work, in turn, made it possible for the brothers to design a machine that would fly. In 1903 the Wrights built their first airplane, which cost less than $1,000. They even designed and built their own source of propulsion-a lightweight gasoline engine. When they started the engine on December 17, the airplane pulsated wildly before taking off. The plane managed to stay aloft for 12 seconds, however, and it flew 120 feet.

By 1905, the Wrights had perfected the first airplane that could turn, circle, and remain airborne for half an hour at a time. Others had flown in balloons and hang gliders, but the Wright brothers were the first to build a full-size machine that could fly under its own power. As the contributors to one of the most outstanding engineering achievements in history, the Wright brothers are accurately called the fathers of aviation.

Lilienthal's idea about controlling airborne vehicles was _________ the Wrights.


Read the given passage carefully and attempt the questions that follow.

It is an old saying that knowledge is power. Education is an instrument that imparts knowledge and therefore, indirectly controls power. Therefore, ever since the dawn of our civilisation, persons in power have always tried to supervise or control education. It has been the handmaid of the ruling class. During the Christian era, the ecclesiastics controlled the institution of education and diffused among the people the gospel of the Bible and religious teachings. These gospels and teachings were no other than a philosophy for the maintenance of the existing society. It taught the poor man to be meek and to earn his bread with the sweat of his brow, while the priests and the landlords lived in luxury and fought duels for the slightest offence. During the Renaissance, education passed more from the clutches of the priest into the hands of the prince. In other words, it became more secular. Under the control of the monarch, education began to devise and preach the infallibility of its masters, the monarch or king. It also invented and supported fantastic theories like “The Divine right Theory” and that the king can do no wrong, etc. With the advent of the industrial revolution, education took a different turn and had to please the new masters. It now no longer remained the privilege of the baron class, but was thrown open to the new rich merchant class of the society. The philosophy which was in vogue during this period was that of “Laissez Faire” restricting the function of the state to a mere keeping of laws and order while on the other hand, in practice the law of the jungle prevailed in the form of free competition and the survival of the fittest.

A new analysis has determined that the threat of global warming can still be greatly diminished if nations cut emissions of heat-trapping greenhouse gases by 70% this century. The analysis was done by scientists at the National Centre for Atmospheric Research (NCAR). While global temperatures- would· rise, the most dangerous potential aspects of climate change, including massive losses of Arctic sea ice and permafrost and significant sea-level rise, could be partially avoided. 

This research indicates that we can no longer avoid significant warming during this century, said NCAR scientist Warren Washington, the study paper's lead author. But, if the world were to implement this level of mission cuts, we could stabilise the threat of climate change, he added. Average global temperatures have armed by close to I C since the pre-industrial era. 

Much of the warming is due to human-produced emissions of greenhouse gases, predominantly carbon dioxide. This heat-trapping gas has increased from a pre-industrial level of about 284 parts per million (ppm) in the atmosphere to more than 380 ppm today. With research showing that additional warming of about l °C may be the threshold for dangerous climate change, the European Union has called for dramatic cuts in emissions of carbon dioxide and other greenhouse gases.

To examine the impact of such cuts on the world's climate. Washington and his colleagues ran a series of global studies with the NCAR based Community Climate System Model (CCSM). They assumed that carbon dioxide levels could be held to 450 ppm at the end of this century. In contrast, emissions are now on track to reach about 750 ppm by 2100 if unchecked.

The team's results showed that If carbon dioxide were held to 450 ppm, global temperatures would increase by 0.6 ·c above current readings by the end of the century.

Why has the European Union called for dramatic cuts in carbon dioxide and greenhouse gas emissions?

Teaching, more even than most other professions, has been transformed during the last hundred years from a small, highly skilled profession concerned with a minority of the population, to a large and important branch of public service. The profession has a great and honourable tradition, extending from the dawn of history until recent times, but any teacher in the modern world who allows himself to be inspired by the ideals of his predecessors is likely to be made sharply aware that it is not his function to teach what he thinks, but to instill such beliefs and prejudices as are thought useful by his employers.

One of South America's mysteries is Easter Island. Easter Island, also called Rapa Nui and Isla de Pascua, 3600 Ion (2,237mi) west of Chile, is a volcanic island with an interesting and partly unknown history. The island was named by the Dutch explorer Jacob Roggeveen because he encountered it on Easter Sunday 1722. He was the first European to find the island. The official name of the island, Isla de Pascua, means Easter Island in Spanish. This island is famous because of the approximately 887 huge statues which were found there. The statues consist of heads and complete torsos, the largest of which weight 84 tons! These monuments, called moai, were carved out of compressed volcanic ash, called tuff, which was found at a quarry ar a place called Rano Raraku. Statues are still being found. Some of the monuments were left only half-carved. Nobody knows why Rano Raraku was abandoned. It is thought that the statues were carved by the ancestors of the modern Polynesian inhabitants. But, the purpose of the statues and the reason they have abandoned remain mysteries. 

What are the statues made of?
