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.

In 1954, a Bombay economist named A.D. Shroff began a forum of free Enterprise, whose ideas on economic development were somewhat at odds with those then influentially articulated by the Planning Commission of the Government of India. Shroff complained against the 'indifference, if not discouragement, with which the state treated entrepreneurs.
At the same time as Shroff, but independently of him, a journalist named Philip Spratt was writing a series of essays in favour of free enterprise. Spratt was a Cambridge communist who was sent by the party in the 1920s to the foment revolution in the subcontinent. detected in the act, he spent many years in an Indian jail. The books he read in the prison, and his marriage to an Indian woman afterward, inspired a steady move rightwards. By the 1950s, he was editing a pro-American weekly from Banglore, called mysIndia. there he inveighed against the economic policies of the government of India. These, he said, treated the entrepreneur 'as a criminal who has dared to use his brain independently of the state to create wealth and give employment’. The state’s chief planner, P.C. Mahalanobis had surrounded himself with Western leftists and Soviet academicians, who reinforced his belief in 'rigid control by the government overall activities’. The result, said Spratt, would be `the smothering of free enterprise, a famine of consumer goods, and the tying down of millions of workers to soul-deadening techniques.'
The voices of men like Spratt and Shroff were drowned in the chorus of popular support for a model of heavy industrialization funded and directed by the governments. The 1950s were certainly not propitious times for free marketers in India. But from time to time their ideas were revived. After the rupee was devalued in 1966, there were some moves towards freeing the trade regime and hopes that the licensing system would also be liberalized. However, after Indira Gandhi split the Congress Party in 1969, her government took its `left turn’, nationalizing a fresh range of industries and returning to economic autarky.

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.
In the light of the given passage which of the following is not true?
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.

Management education gained new academic stature within US Universities and greater respect from outside during the 1960 and 1970s. Some observers attribute the competitive superiority of US corporations to the quality of business education. In1978, a management professor, Herbert A. Simon of Carnegie Mellon University, won the Nobel Prize in economics for his work in decision theory. And the popularity of business education continued to grow, since 1960, the number of master’s degrees awarded annually has grown from under 5000 to over 50,000 in the mid-1980’s as the MBA has become known as ‘the passport to the good life’.
By the 1980s, however, US business schools faced critics who charged that learning had little relevance to real business problems. Some went so far as to blame business schools for the decline in US competitiveness.
Amidst the criticisms, four distinct arguments may be discerned. The first is that business schools must be either unnecessary or deleterious because Japan does so well without them. Underlying this argument is the idea that management ability cannot be taught, one is either born with it or must acquire it over years of practical experience. A second argument is that business schools are overly academic and theoretical. They teach quantitative models that have little application to real-world problems. Third, they give inadequate attention to shop floor issues, production processes and to management resources. Finally, it is argued that they encourage undesirable attitudes in students, such as placing value on the short term and ‘bottom line’ targets, while neglecting longer-term development criteria. In summary, some business executives complain that MBA’s are incapable of handling day to day operational decisions, unable to communicate and to motivate people, and unwilling to accept responsibility for following through on implementation plans. We shall analyze these criticisms after having reviewed experiences in other countries.
In contrast to the expansion and development of business education in the United States and more recently in Europe, Japanese business schools graduate no more than two hundred MBA’s each year. The Keio Business School (KBS) was the only graduate school of management in the entire country until the mid-1970s and it still boasts the only two-year master's programme. The absence of business schools in Japan would appear in contradiction with the high priority placed upon learning by its Confucian culture. Confucian colleges taught administrative skills as early as 1630 and Japan wholeheartedly accepted Western learning following the Meiji restoration of 1868 when hundreds of students were dispatched to universities in US, Germany, England, and France to learn the secrets of Western technology and modernization. Moreover, the Japanese educational system is highly developed and intensely competitive and can be credited for raising the literary and mathematical abilities of the Japanese to the highest level in the world.
Until recently, Japan corporations have not been interested in using either local or foreign business schools for the development of their future executives. Their in-company training programs have sought the socialization of newcomers, the younger the better. The training is highly specific and those who receive it have neither the capacity nor the incentive to quit. The prevailing belief, says Imai, ‘is management should be born out of the experience and many years of effort and not learnt from educational institutions.’ A 1960 survey of Japanese senior executives confirmed that a majority (54%) believed that managerial capabilities can be attained only on the job and not in universities.
However, this view seems to be changing: the same survey revealed that even as early as 1960, 37% of senior executives felt that the universities should teach integrated professional management. In the 1980’s a combination of increased competitive pressures and greater multi-nationalization of Japanese business are making it difficult for many companies to rely solely on uponinternally trained managers. This has led to rapid growth of local business programmes and greater use of American MBA programmes. In 1982-83, the Japanese comprised the largest single group of foreign students at Wharton, where they not only learnt the latest techniques of financial analysis but also developed worldwide contacts through their classmates and became Americanized, something highly useful in future negotiations. The Japanese, then do not ‘do without’ business schools, as is sometimes contended. But the process of selecting and orienting new graduates, even MBA’s, into corporations is radically different than in the US. Rather than being placed in highly paying staff positions, new Japanese recruits are assigned responsibility for operational and even menial tasks. Success is based upon Japan’s system of highly competitive recruitment and intensive in-company management development, which in turn are grounded in its tradition of universal and rigorous academic education, life-long employment and strong group identification.
The harmony among these traditional elements has made the Japanese industry highly productive and given corporate leadership a long term view. It is true that this has been achieved without much attention to university business education, but extraordinary attention has been devoted to the development of managerial skills, both within the company and through participation in programmes sponsored by the Productivity Center and other similar organizations.
The following reasons were responsible for the growth of popularity of business schools among students except

Civilization is basically a vital kind of grouping. Without civilizations, the world as we know it would not be. Civilizations have different qualities than regular groups of people such as nomads. For example, a civilization develops surpluses of things which helps the people be a stable community. These surpluses also create the construction and growth of cities and help develop secure, formal states. The government is also present in civilizations. One very important part of a civilization is an advanced writing method. A civilization can only be complete with all of these factors, or it will just fall apart. Nomads are nowhere close to being a civilization even though sometimes groups of nomads have good technology. The words 'culture' and 'civilization' have been often used synonymously, though they have clearly defined meanings differentiating them. 'Civilization' means the betterment of ways of living, making Nature bend to fulfill the needs of humankind. It includes also organizing societies into politically well-defined groups working collectively for improved conditions of life in matters of food, dress, communication, and so on. Thus a group considers itself as civilized, while others were looked down upon as barbarians. This has led to wars and holocausts, resulting in the mass destruction of human beings. What are the good parts of our civilization? First and foremost there are order and safety. If today I have a quarrel with another man, I do not get beaten merely because I am physically weaker and he can kick me down. I go to law, and the law will decide as fairly as it can between the two of us. Thus in disputes between man and man right has taken the place of might. Moreover, the law protects me from robbery and violence. Nobody may come and break into my house, steal my goods or run off with my children. Of course, there are burglars, but they are very rare, and the law punishes them whenever it catches them. It is difficult for us to realize how much this safety means. Without safety, these higher activities of mankind which make up civilization could not go on. The inventor could not invent, the scientist find out or the artist make beautiful things. Hence, order and safety, although they are not themselves civilization are things without which civilization would be impossible. They are as necessary to our civilization as the air we breathe is to us, and we have grown so used to them that we do not notice them any more than we notice the air. Another great achievement of our civilization is that today civilized men are largely free from the fear of pain. They still fall ill, but illness is no longer the terrible thing it used to be... Not only do men and women enjoy better health; they live longer than they ever did before, and they have a much better chance of growing up... Thirdly, our civilization is more secure than any that have gone before it. This is because it is much more widely spread... Previous civilizations were specialized and limited, they were like oases in a desert.
What according to the author, is the second merit of the present civilization?
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.
The Wrights' interest in flight grew into a ________.

The world dismisses curiosity by calling it idle, or mere idle curiosity – even though curious persons are seldom idle. Parents do their best to extinguish curiosity in their children because it makes life difficult to be faced every day with a string of unanswerable questions about what makes fire hot or why grass grows. Children whose curiosity survives parental discipline are invited to join our university. Within the university, they go on asking their questions and trying to find the answers. In the eyes of a scholar, that is mainly what a university is for. Some of the questions that scholars ask seem to the world to be scarcely worth asking, let alone answering. They ask questions too minute and specialized for you and me to understand without years of explanation. If the world inquires one of them why he wants to know the answer to a particular question, he may say, especially if he is a scientist, that the answer will, in some obscure way, make possible a new machine or weapon or gadget. He talks that way because he knows that the world understands and respects utility. But to you who are now part of the university, he will say that he wants to know the answer, simply because he does not know it. The way a mountain climber wants to climb a mountain simply because it is there. Similarly, a historian when asked by outsiders why he studies history may come out with the argument that he has learned to repeat on such occasions, something about the knowledge of the past, making it possible to understand the present and mold the future. But if you really want to know why a historian studies the past, the answer is much simpler: something happened, and he would like to know what. All this does not mean that the answers which scholars find to their questions have no consequences. They may have enormous consequences, but these seldom form the reason for asking the question or pursuing the answers. It is true that scholars can be put to work answering questions for the sake of the consequences, as thousands are working now, for example, in search of a cure for cancer. But this is not the primary function of the scholar, for the consequences are usually subordinate to the satisfaction of curiosity.
The primary function of a scholar is different from the search for a cure for cancer because

MY LOVE OF NATURE, goes right back to my childhood, to the times when I stayed on, my grandparents' farm in Suffolk. My father was in the armed forces, so we were always moving and didn't have a home base for any length of time, but I loved going there. I think it was my grandmother who encouraged me more than anyone: she taught me the names of wild flowers and got me interested in looking at the countryside, so it seemed obvious to go on to do Zoology at University.
I didn't get my first camera until after I'd graduated, when I was due to go diving in Norway and needed a method of recording the sea creatures I would find there. My father didn't know anything about photography, but he bought me an Exacta, which was really quite a good camera for the time, and I went off to take my first pictures of sea anemones and starfish. I became keen very quickly, and learned how to develop and print; obviously I didn't have much money in those days, so I did more black and white photography than colour, but it was all still using the camera very much as a tool to record what I found both by diving and on the shore. I had no ambition at all to be a photographer then, or even for some years afterwards.
Unlike many of the wildlife photographers of the time, I trained as a scientist and therefore my way of expressing myself is very different. I've tried from the beginning to produce pictures that are always biologically correct. There are people who will alter things deliberately: you don't pick up sea creatures from the middle of the shore and take them down to attractive pools at the bottom of the shore without knowing you're doing it. In so doing you're actually falsifying the sort of seaweeds they live on and so on, which may seem unimportant, but it is actually changing the natural surroundings to make them prettier. Unfortunately, many of the people who select pictures are looking for attractive images and, at the end of the day, whether it's truthful or not doesn't really matter to them. It's important to think about the animal first, and there are many occasions when I've not taken a picture because it would have been too disturbing. Nothing is so important that you have to get that shot; of course, there are cases when it would be very sad if you didn't, but it's not the end of the world. There can be a lot of ignorance in people's behaviour towards wild animals and it's a problem that more and more people are going to wild places: while some animals may get used to cars, they won't get used to people suddenly rushing up to them. The sheer pressure of people, coupled with the fact that there are increasingly fewer places where no-one else has photographed, means that over the years, life has become much more difficult for the professional wildlife photographer.
Nevertheless, wildlife photographs play a very important part in educating people about what is out there and what needs conserving. Although photography can be an enjoyable pastime, as it is to many people, it is also something that plays a very important part in educating young and old alike. Of the qualities it takes to make a good wildlife photographer, patience is perhaps the most obvious -you just have to be prepared to sit it out. I'm actually more patient now because I write more than ever before, and as long as I've got a bit of paper and a pencil, I don't feel I'm wasting my time. And because I photograph such a wide range of things, even if the main target doesn't appear I can probably find something else to concentrate on instead.
The writer decided to go to university and study Zoology because

Although the legal systems of England and the United States are superficially similar, they differ profoundly in their approaches to and uses of legal reasons: substantive reasons are more common than formal reasons in the United States, whereas in England the reverse is true. This distinction reflects a difference in the visions of law that prevails in the two countries. In England, the law has traditionally been viewed as a system of rules; the United States favours a vision of law as an outward expression of a community's sense of right and justice.
Substantive reasons, as applied to law, are based on moral, economic, political and other considerations. These reasons are found both "in the law" and ''outside the law" so to speak. Substantive reasons inform the content of a large part of the law: constitutions, statutes, contracts, verdicts and the like. Consider, for example, a statute providing that "no vehicles shall be taken into public parks." Suppose that no specific rationales or purposes were explicitly written into the statute, but that it was clear (from its legislative history) that the substantive purpose of the statute was to ensure quiet and safety in the park. Now suppose that a veterans' group mounts a World War II jeep (in running order but without a battery) as a war memorial on a concrete slab in the park, and charges are brought against its members. Most judges in the United States would find the defendants not guilty because what they did had no adverse effect on the park's quiet and safety. Formal reasons are different in that they frequently prevent substantive reasons from coming into play, even when substantive reasons are explicitly incorporated into the law at hand. For example, when a document fails to comply with stipulated requirements, the court may render the document legally ineffective. A Will requiring written witness may be declared null and void and, therefore, unenforceable for the formal reason that the requirement was not observed. Once the legal rule - that a Will is invalid for lack of proper witnessing - has been clearly established, and the legality of the rule is not in question, application of that rule precludes from consideration substantive arguments in favour of Will's validity or enforcement. Legal scholars in England and the United States have long bemused themselves with extreme examples of formal and substantive reasoning. On the one hand, formal reasoning in England has led to wooden interpretations of statutes and an unwillingness to develop the common law through judicial activism. On the other hand, freewheeling substantive reasoning in the United States has resulted in statutory interpretations so liberal that the texts of some statutes have been ignored.
It can be inferred from the passage that English judges would like to find the veterans' group discussed in the second paragraph guilty of violating the statute because

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.
As per the above paragraph, which of the following was the first accomplishment of Thomas Edison?
