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:

In recent weeks, the writers William Dalrymple and Patrick French, among others, have come before a fusillade of criticism in India, much of it questioning not their facts, not their interpretations, but their foreignness.
"Who gets to write about India?" The Wall Street Journal asked on Wednesday in its own report on this Indian literary feuding. It is a complicated question, not least because to decide who gets to write about India, you would need to decide who gets to decide who gets to write about India. Rather than conjecturing some Committee for the Deciding of the Deciding of Who Gets to Write about India, it might be easier to let writers write what they please and readers read what they wish.
The accusations pouring forth from a section of the Indian commentariat are varied. Some criticism is of a genuine literary nature, fair game, customary, expected. But lately a good amount of the reproaching has been about identity.
In the case of Mr. Dalrymple, a Briton who lives in New Delhi, it is - in the critics' view - that his writing is an act of re-colonization. In the case of Mr. French, it is that he belongs to a group of foreign writers who use business-class lounges and see some merit in capitalism and therefore do not know the real India, which only the commentariat member in question does.
What is most interesting about these appraisals is that their essential nature makes reading the book superfluous, as one of my Indian reviewers openly admitted. (His review was not about the book but about his refusal to read the book.) The book is not necessary in these cases, for the argument is about who can write about India, not what has been written.
For critics of this persuasion, India surely seems a lonely land. A country with a millennial history of Hindus, Christians, Jews, Muslims and Buddhists living peaceably together; a country of hundreds.of dialects in which so many Indians are linguistic foreigners to each other, and happily, tolerantly so; a country that welcomes foreign seekers (of yoga poses, of spiritual wisdom, of ancestral roots) with open arms; a country where, outside the elite world of South Delhi and South Bombay, I have not heard an Indian ask whether outsiders have a right to write, think or exist on their soil.
But it is not just this deep-in-the-bones pluralism that challenges the who-gets-to write- about India contingent. It is also that at the very heart of India's multifarious changes today is this glimmering idea: that Indians must be rewarded for what they do, not who they are.
Identities you never chose - caste, gender, birth order - are becoming less important determinants of fate. Your deeds - how hard you work, what risks you take - are becoming more important.
It is this idea, which I have found pulsating throughout the Indian layers, that leaves a certain portion of the intelligentsia out of sync with the surrounding country. As Mr. French has observed, there is a tendency in some of these writers to value social mobility only for themselves. When the new economy lifts up the huddled masses, then it becomes tawdry capitalism and rapacious imperialism and soulless globalization.
Fortunately for those without Indian passports, the nativists' vision of India is under demographic siege. The young and the relentless are India's future. They could not think more differently from this literatis.
They savor the freedom they are gaining to seek their own level in the society and to find their voice, and they tend to be delighted at the thought that some foreigners do the same in India and love their country as much as they do.
The writer uses the phrase, 'who gets to write about India contingent' in this passage to refer to:
Direction: The passage given below is followed by a set of question. Choose the most appropriate answer to each question.
Ahmedabad’s Sunday market that sells junk is this 35-year-old artist’s favourite hunting ground. That’s where he picks saw-blades, printer toners, monitors, busted VCDs and hard disks, video players and other castaway gems. Back home, he painstakingly dismantles his treasure of scrap and segregates it into big pieces (the video player's outer case), mid-sized (the insides of a hard disk) and small pieces (innards of a mobile). This is art you can get up, close and personal with. The works grab the viewer’s attention at several levels. Aesthetically, the creations themselves - such as Frivolity which uses feathers and terracotta diyas painted in dark fossil green that give it a strange life - appeal in a live-and-kicking sort of way. Look a little closer and hey, you spot a zipper. Then it’s a journey all your own. Your eyes identify hairpins, spray spouts that hairdressers use, paper clips, thread, computer ribbons and the insides of everything from watches to the sliding metal bits that support drawers. You can almost hear the works whirr. So Hashissh, constructed from paper clips, backpack clips, a shining CD and twirled thread, may invite you to study its water-blue, pinks and green or Nelumbeshwar may beckon, bathed in acrylic pink and grey-black. But once you’re standing in front of a piece, you spot the zips and the hairpins. Then you simply visually dismantle Har’s work and rebuild it all over again. Zoom in, zoom out. It’s great fun. Visualising the colour of his work demands a lot of attention, says Har. “During creation, the material is all differently coloured. So there’s a red switch next to a white panel next to a black clip. It can distract. I don’t sketch, so I have to keep a sharp focus on the final look I am working towards.” As his work evolved, Har discovered laser-cutting on a visit to a factory where he had gone to sand-blast one of his pieces. Hooked by the zingy shapes laser-cutting offered, Har promptly used it to speed up a scooter and lend an unbearable lightness of being to a flighty autorickshaw, his latest works. The NID-trained animation designer’s scrap quest was first inspired by a spider in his bathroom in Chennai when he was a teenager. He used a table-tennis ball (for the head), a bigger plastic ball (for the body) and twisted clothes hangers to form the legs. His next idea was to create a crab, and his mother obligingly brought one home from the market so that he could study and copy it. Winning the first Art Positive fellowship offered by Bajaj Capital Arthouse last year gave Har the confidence to believe that he could make it as an artist or ‘aesthete’ as he likes to call himself.
According to the passage, which of the following statements can be inferred?
The question in this section is based on what is stated or implied in the passage given below. For the question, choose the option that most accurately and completely answers the question.
The words invention and Innovation are closely linked, but they are not interchangeable. The inventor is a genius who uses his intellect, imagination, time and resources to create something that does not exist. But this invention may or may not be of utility to the masses. It is the enterprising innovator who uses various resources, skills and time to make the invention available for use. The innovator might use the invention as it is, modifies it or even blend two or more inventions to make one marketable product. A great example is that of the iPhone which is a combination of various inventions. If an invention is the result of countless trials and errors, so can be the case with innovation. Not every attempt to make an invention is successful. Not every innovation sees the light of the day. Benjamin Franklin had the belief that success doesn‘t come without challenge, mistake, and in a few cases failure.
One of the world‘s most famous innovators, Steve Jobs says, ―Sometimes when you innovate, you make mistakes. It is best to admit them quickly and get on with improving your other innovations.‖ Thus, inventors and innovators have to be intrepid enough to take risks; consider failures as stepping stones and not stumbling blocks. Some inventions are the result of a keen observation or a simple discovery. The inventor of Velcro, also called the zipless zipper, is the Swiss engineer George de Mestral. He was hiking in the woods when he found burrs clinging to his clothes and his dog‘s fur. Back at home, he studied the burrs. He discovered that each burr was a collection of tiny hooks which made it cling on to another object. A few years later, he made and patented the strips of fabric that came to us like Velcro. The world of inventions and innovations is a competitive one. But the race does not end here; it is also prevalent in the case of getting intellectual property rights. There have been inventors who failed to get a single patent while there have been some who managed to amass numerous patents in their lifetime. Thomas Edison had 1,093 patents to his credit! We relate the telephone with Alexander Graham Bell. It is believed that around the same time, Antonio Meucci had also designed the telephone, but due to a lack of resources and various hardships, he could not proceed with the patent of his invention. It is also believed that Elisha Gray had made a design for the telephone and applied for the patent at the U.S. patent office on the same day as Graham Bell did. By sheer chance, Graham‘s lawyer‘s turn to file the papers came first. Hence, Graham was granted the first patent for the telephone. It is not easy, and at times almost impossible, for an inventor to be an innovator too. There are very few like Thomas Edison who graduated from being an incredible inventor to a successful manufacturer and businessman with brilliant marketing skills. While innovations that have helped to enhance the quality of life are laudable, equally laudable are the inventions that laid the foundation of these very innovations.
It is believed that Graham Bell became the first patent holder of the telephone because of

The summer he turned 82, my father lost his stories. He was still vibrant, garrulous and energetic, and initially, none of us noticed that his anecdotes were getting repetitive, that he was forgetting names and places, that he was confusing times and references. A man of many narratives, we listened to his oft-repeated tales, sometimes with feigned patience and sometimes with visible impatience.
Till the day the stories stopped. The words dried out. The memories disappeared. The change happened so gradually that its final suddenness took us, his immediate family by complete surprise. And when the stories dried up, the energy seemed to drain away from his soul. This loss of energy was immediately and visibly apparent as this was one trait, above all others that characterized my father.
A child of Partition, Baba had left his native Barisal in present-day Bangladesh, on the eve of this momentous event in 1947, at the age of 14. My grandmother, widowed since the birth of my father, her youngest son, decided to leave their sprawling homestead with extensive farming lands and immigrate to the yet-to-be formed republic of India, along with her four other sons. Thus, family lore tells us, she liquidated some of her assets, packed her immediate family and necessary belongings onto a steamer and sailed into the teeming, seething city of Calcutta to set up a new life.
A seminal rupture in the subcontinent, Partition had wreaked havoc among countless families, uprooted and flung far and wide without any recourse. Baba often became that recourse – his contribution making a significant difference to families struggling to survive with some degree of dignity. It seemed his experience of early loss and deprivation had in a strangely converse way, endowed him with a generosity of soul that I have yet to encounter in another person.
It was thus shocking to see this extraordinary man with the mind, heart and soul of a Colossus shorn of his spirit.
In an effort to revive his flagging interest, I urged him to start writing down stories from his life. I bought him a notebook and with great flourish announced his assignment.
Stories were my particular stock in trade. I’d nurtured an early passion for storytelling and story writing into a teaching career focussed on literacy. I used specific strategies to build a writing habit in my students, centered on the belief that we all have stories to tell. As the children became confident and joyful storytellers, their acquisition of benchmarked literacy skills outstripped that of their peers.
Could I use these same strategies to draw the forgotten stories from Baba? Would these forgotten stories, in turn, help him reconstruct a sense of self?

What role did the author’s father play for families uprooted by the Partition?
Paragraph: Economists have long recognized a persistent and unfounded belief among the population which has come to be known as the anti-foreign bias. As a result of this bias, most people systematically underestimate the economic benefits of interactions with foreign nations. Some psychologists believe that this bias is rooted in a natural distrust of the "other," while others believe that a form of folk wisdom, seemingly in accord with common sense but nonetheless incorrect, explains the bias. This wisdom asserts that in any transaction there is a winner and a loser and any foreign nation that wants to engage in trade must be doing so because it seeks its own advantage. But nothing could be further from truth.
No less an authority than Adam Smith, one of the fathers of the modern free market system, spoke glowingly of foreign trade in his influential treatise Wealth of Nations. "What is prudence in the conduct of every private family, can scarce be folly in a great kingdom," said Smith. His point is simple. A baker trades his bread to the cobbler for shoes and both men benefit from the trade because of the value of specialization. The same principle works for nations. Even more startling, a basic economic theorem, the Law of Comparative Advantage, states that mutually beneficial trade is possible even if one nation is less productive than the other.
Suppose a citizen of Country X can produce either 10 computers or five bushels of wheat and a citizen of Country Y can produce either three computers or two bushels of wheat. If one citizen from Country X switches from producing wheat to computers and three citizens from Country Y switch from producing computers to wheat, there is a net gain of one computer and one bushel of wheat.
As it is described in the passage, which of the following most closely resembles "folk wisdom?"
Read the given passage carefully and answer the questions that follow.
There is a fairly universal sentiment that the use of nuclear weapons is clearly contrary to morality and that its production probably so, does not go far enough. These activities are not only opposed to morality but also to the law if the legal objection can be added to the moral, the argument against the use and the manufacture of these weapons will considerably be reinforced. Now the time is ripe to evaluate the responsibility of scientists who knowingly use their expertise for the construction of such weapons, which has deleterious effect on mankind.
To this must be added the fact that more than 50 percent of the skilled scientific manpower in the world is now engaged in the armaments industry. How appropriate it is that all this valuable skill should be devoted to the manufacture of weapons of death in a world of poverty is a question that must touch the scientific conscience.
A meeting of biologists on the Long-Term Worldwide Biological consequences of nuclear war added frightening dimension to those forecasts. Its report suggested that the long biological effects resulting from climatic changes may at least be as serious as the immediate ones. Sub-freezing temperatures, low light levels, and high doses of ionizing and ultraviolet radiation extending for many months after a large-scale nuclear war could destroy the biological support system of civilization, at least in the Northern Hemisphere. Productivity in natural and agricultural ecosystems could be severely restricted for a year or more. Post war survivors would face starvation as well as freezing conditions in the dark and be exposed to near lethal doses of radiation. If, as now seems possible, the Southern Hemisphere were affected also, global disruption of the biosphere could ensue. In any event, there would be severe consequences, even in the areas not affected directly, because of the interdependence of the world economy. In either case the extinction of a large fraction of the earth’s animals, plants and microorganisms seem possible.
The population size of Homo sapiens conceivably could be reduced to prehistoric levels or below, and extinction of the human species itself cannot be excluded.
It appears from the passage that the use of nuclear weapons is considered against morality by

Rural development in India has witnessed several changes over the years in its emphasis, approaches, strategies and programmes. It has assumed a new dimension and perspectives as a consequence. Rural development can be richer and more meaningful only through the participation of the clienteles of development. Just as implementation is the touchstone for planning, people's participation is the centre-piece in rural development.
People's participation is one of the foremost pre-requisites of development process both from procedural and philosophical perspectives. For the development planners and administrators, it is important to solicit the participation of different groups of rural people, to make the plans participatory.
Rural development aims at improving rural people's livelihoods in an equitable and sustainable manner, both socially and environmentally, through better access to assets and services and control over productive capital. The basic objectives of Rural Development Programmes have been alleviation of poverty and unemployment through creation of basic social and economic infrastructure, provision of training to rural unemployed youth and providing employment to marginal farmers/labourers to discourage seasonal and permanent migration to urban areas.
Rural development is the main pillar of our nation's development. In spite of rapid urbanisation, a large section of our population still lives in the villages. Secondly. rural India has Jagged behind in development because of many historical sectors. Though the 11th plan began in very behavioural circumstances with the economy has grown at the rate of 7.7% per year in the 10th plan period, there still existed a big challenge to correct the development imbalances and to accord due priority to development in rural areas.
Ministry of Rural Development is implementing a number of programmes aimed at sustainable holistic development in rural areas. The thrust of these programmes is on all-round economic and social transformation in rural areas, though a multi-pronged strategy aiming to reach out to the most disadvantaged sections of the society.
Although concrete efforts have been initiated by the Government of India through several plans and measures to alleviate poverty in rural India, there still remains much more to be done to bring prosperity in the lives of the people in rural areas. At present, technology dissemination is uneven and slow In rural areas.
Which of the following is true according to the passage?
I. Urbanisation has resulted in a majority of Indian population living in urban areas.
II. The economic growth of the 10th Five Year Plan did not translate into proportionate rural development.
III. The efforts of the Government of India for poverty alleviation have been met with complete failure.

The Constitution of the United States protects both property rights and freedom of speech. At times, these rights conflict. The resolution then requires a determination as to the type of property involved. If the property is private and not open to the general public, the owner may absolutely deny the exercise of the right of free speech thereon. On the other hand, if public land is at issue, the First Amendment protections of expression are applicable. However, the exercise of free speech thereon is not absolute. Rather, it is necessary to determine the appropriateness of the forum. This requires that consideration be given to a number of factors including character and normal use of the property, the extent to which it is open to the public, and the number and types of persons who frequent it. If the forum is clearly public or clearly private, the resolution of the greater rights is relatively straight forward.
In the area of the quasi-public property, balancing these rights has produced a dilemma. This is the situation when a private owner permits the general public to use his property. When· persons seek to use the land for passing out handbills or picketing, how is a conflict between property rights and freedom of expression resolved? The precept that a private property owner surrenders his rights in proportion to the extent to which he opens up his property to the public is not new. In 1675, Lord Chief Justice Hale wrote that when private property is "affected with a public interest, it ceases to be private." Throughout the development of Anglo-American law; the individual has never possessed absolute dominion over property. Land becomes clothed with a public interest when the owner devotes his property to a use in which the public has an interest. In support of this position, the chairman of the board of the Wilde Lake Shopping Centre in Columbia, Maryland said: The only real purpose and justification of any of these centres is to serve the people in the area - not the merchants, not the developers, not the architects. The success or failure of a regional shopping centre will be measured by what it does for the people it seeks to serve. These doctrines should be applied when accommodation must be made between a shopping centre owner's private property rights and the public's right to free expression. It is hoped that when the Court is asked to balance these conflicting rights it will keep in mind what Justice Black said in 1945: "When we balance the constitutional rights of owners of property against those of the people to enjoy (First Amendment) freedom(s) ..... we remain mindful of the fact that the latter occupy a preferred position."
A conflict between property rights and freedom of speech might arise in all of the following situations, except

Thomas Edison was born in 1847 In Milan, Ohio. He was nicknamed 'Al' at an early age. At age 11, Edison moved to Michigan where he spent the remainder of his childhood. Thomas Edition struggled at school but learned to love reading and conducting experiments from his mother who taught him at home. At age 15, Edison became a 'tramp together', sending and rece1vrng messages via Morse code, an electronically-conveyed alphabet using different clicks for each letter. In 1870, Edison moved to New York City and improved the stock ticker. He soon formed his own company that manufactured the new stock tickers. He also began working on the telegraph and invented a version that could send our messages at once. Edison then moved with his family to New Jersey where he started his famous laboratory. In 1877, Edison, with help from 'muckers', individuals from around the world looking to make fortune in America, invented the phonograph. The phonograph was a machine that recorded and played back sounds. In 1878, Edison invented the light bulb as well as the power grid system, which could generate electricity and deliver it to homes through a network of wires. He subsequently started the Edison Electric Light Company in October of 1878. Edison continued to invent or improve products and make significant contributions to X-ray technology, storage batteries and motion pictures (movies). Edison was a prolific inventor, holding 1,093 US patents in his name, as well as many patents in the United Kingdom, France, and Germany.
