My daily routine My name is Mirzayev Begzod. I work in the traffic safety department of Boka district of Tashkent region. My work activity consists of 1. Ensuring road safety. I like the work myself and as a result of this I have achieved a number of successes. Among them, it is possible to add that I entered the Tashkent University of Information Technologies on the basis of a recommendation. I believe that after graduating, I will be a person who will benefit the society Description of your home town I was born in Boka district of Tashkent region. Boka district is a district of Tashkent region. Located in the southwest of the region. It was established on May 18, 1943. It borders with Akkurgan district in the north-west, Piskent district in the northeast, Bekabad district in the south, Akaltin and Gulistan districts of Syrdarya region in the west, and the Republic of Tajikistan in the east. . The area is 0.59 thousand km². The population is 127.5 thousand people. The population is mainly Uzbek, Tajik, Kazakh, Russian, Tatar, Turkish and other nationalities. Boka district is the leading branch of the district's economy, specializing mainly in cotton growing, vegetable growing and animal husbandry. A computer system A computer system is an electronic system consists of many parts works together to make the computer work. Computers work mainly to perform a specific task given by the user. In a desktop computer, we see three parts of the computer such as input unit (keyboard and mouse), output unit (monitor and printer), and system unit (rectangular box). In a laptop, all the parts of a computer are embedded on a single place. Hence, it is easy to carry them from one place to another place. Instead of using mouse, we use touch pad in laptops. Generally, a computer system consists of four important components: Input unit CPU (Central Processing Unit) Output unit Memory unit Kompyuter tizimi Kompyuter tizimi - bu kompyuterning ishlashi uchun birgalikda ishlaydigan ko'plab qismlardan iborat elektron tizim. Kompyuterlar asosan foydalanuvchi tomonidan berilgan aniq vazifani bajarish uchun ishlaydi. Ish stoli kompyuterida biz kompyuterning uchta qismini ko'ramiz, masalan, kiritish bloki (klaviatura va sichqoncha), chiqish bloki (monitor va printer) va tizim bloki (to'rtburchak quti). Noutbukda kompyuterning barcha qismlari bitta joyga o'rnatilgan. Shuning uchun ularni bir joydan boshqa joyga olib borish oson. Sichqonchani ishlatish o'rniga biz noutbuklarda sensorli paneldan foydalanamiz. Kompyuter tizimining muhim komponentlari Umuman olganda, kompyuter tizimi to'rtta muhim komponentdan iborat: Kirish birligi Markaziy protsessor (markaziy protsessor) Chiqish birligi Xotira birligi Computer usage The role of the computer in our lives is currently growing from day to day. It can be explained by the fact that computers help people to do their work much more easily and quickly. Computers can be characterised, as very comfortable, reliable and accurate. The biggest advantage is the price of computers, they are quite cheap. They give people very quick and quality information, so in such a way people don’t have to spend their time, turning leaves of dozens of books. Computers are easy to use, so you don’t have to be a genius to be able to work on it. And even if it is hard for you to learn it, you can buy some videos and books that will help you to do it. In today's world, computers are used nearly in all branches of industry. Even in that one that are dangerous and harmful to human health. Scientists can’t imagine space research without using computers. Today computers can diagnose very severe illnesses and help to carry out operations. Using a computer you can search something on the internet. It has many advantages. You can exchange information electronically. The Internet users can enjoy online media and they can help other people to solve their problems. It expands our knowledge and stimulates our curiosity. Using the internet, you can meet different and interesting people. The internet also informs us about new trends. It provides us the possibility to talk with our friends online. The Internet helps us to use less television and watch only those films, which we want. The computers have some disadvantages. Computer viruses are very dangerous. Such computer viruses can delete all files that are in your computer. But in my opinion, computers are very useful and necessary in our lives. Despite some disadvantages, I think that a computer is the very important machine. I am sure that the computers have a great influence on our lives. Brief history of computer industry In 1822 Charles Babbage, professor of mathematics at Cambridge University in England, created the “Analytical engine”, a mechanical calculator that could automatically produce mathematical tables, a tedious and error-prone manual task in those days. Babbage conceived of a large-scale, steam-driven (!) model, that could perform a wide range of computational tasks. The model has never been completed as revolving shafts and gears could not be manufactured with the crude industrial technology of the day. By the 1880s manufacturing technology had improved to the point that practical mechanical calculators, including versions of Babbage's Analytical engine, could be produced. The new technology achieved worldwide fame in tabulating the US Census of 1890. The Census Bureau turned to a new tabulating machine invented by Herman Hollerith, which reduced personal data to holes punched in paper cards. Tiny mechanical fingers "felt" the holes and closed an electrical circuit that in turn advanced the mechanical counter. Hollerith's invention eventually became the foundation on which the International Business Machines Corporation (IBM) was built. Analog and digital calculators with electromechanical components appeared in a variety of military and intelligence applications in 1930s. Many people credit the invention of the first electronic computer to John Vincent Atanasoff. He produced working models of computer memory and data processing units at the University of Iowa in 1939 although had never assembled a complete working computer. World War II prompted the development of the first working all-electronic digital computer, Colossus, which the British secret service designed to crack Nazi codes. Similarly, the need to calculate detailed mathematical tables to help aim cannons and missiles led to the creation of the first, general-purpose computer, the electronic numerical integrator and calculator ENIAC at the University of Pennsylvania in 1946. After leaving their university (arguing over the patent rights) developers of ENIAC, J. Prosper Eckert and John Mauchly, turned to business pursuits. They also had an ugly scandal with an academic colleague, John von Neumann, whom they accused of having unfairly left their names off the scientific paper that first described the computer and allowed von Neumann to claim that he had invented it. Eckert and Mauchly went on to create UNIVAC for the Remington Rand Corporation, an early leader in the computer industry. UNIVAC was the first successful commercial computer, and the first model was sold to the US Census Bureau in 1951. The Brain the most powerful computer in the Universe In ancient times men did not think that the brain was the center of mental activity. Aristotle, the philosopher of ancient Greece, thought that the mind was based in the heart. It was until the 18th century that man realized that the whole of the brain was involved in the workings of the mind. During the 19th century scientists found that when certain parts of the brain were damaged men lost the ability to do certain things. And so, people thought that each part of the brain controlled a different activity. But modern research has found that this is not so.It is not easy to say exactly what each part of the brain does. In the past 50 years there has been a great increase in the amount of research being done on the brain. Chemists and biologists have found that the way the brain works is far more complicated than they had thought. In fact many people believe thatwe are only now really starting to learn the truth about how human brain works. The more scientists find out, the more questions they are unable to answer. For instance, chemists have found that over 100.000 chemical reactions take place in the brain every second. Scientists hope if we can discover how the brain works, the better use we will be able to put it to. For example, how do we learn language? Man differs most from all the other animals in his ability to learn and use language but we still do not know exactly how this is done. As long as the brain is given plenty of exercise it keeps its power. It has been found that an old person who has always been mentally active has a quicker mind than a young person who has done only physical work. It is now thought that the more work we give our brains, the more work they are able to do. Other people now believe that we use only 1% of our brains’ full potential.They say that the only limit on the power of the brain is the limit of what we think is possible. This is probably because of the way we are taught as children. When we first start learning to use our minds we are told told what to do, for example, to remember certain facts, but we are not taught how our memory works and how to make the best use of it. Computer graphics Computer graphics deals with generating images with the aid of computers. Today, computer graphics is a core technology in digital photography, film, video games, cell phone and computer displays, and many specialized applications. A great deal of specialized hardware and software has been developed, with the displays of most devices being driven by computer graphics hardware. It is a vast and recently developed area of computer science. The phrase was coined in 1960 by computer graphics researchers Verne Hudson and William Fetter of Boeing. It is often abbreviated as CG, or typically in the context of film as computer generated imagery (CGI). The non-artistic aspects of computer graphics are the subject of computer science research. Some topics in computer graphics include user interface design, sprite graphics, rendering, ray tracing, geometry processing, computer animation, vector graphics, 3D surfaces, visualization, scientific modeling, shaders, GPU design, implicit computing, image processing, computational photography, scientific visualization, computational geometry and computer vision, among others. The overall methodology depends heavily on the underlying sciences of geometry, optics, physics, and perception. Computer graphics is responsible for displaying art and image data effectively and meaningfully to the consumer. It is also used for processing image data received from the physical world, such as photo and video content. Computer graphics development has had a significant impact on many types of media and has revolutionized animation, movies, advertising, video games, in general. The Internet and WWW history The history of the Internet has its origin in the efforts to build and interconnect computer networks that arose from research and development in the United States and involved international collaboration, particularly with researchers in the United Kingdom and France. Computer science was an emerging discipline in the late 1950s that began to consider time-sharing between computer users, and later, the possibility of achieving this over wide area networks. Independently, Paul Baran proposed a distributed network based on data in message blocks in the early 1960s and Donald Davies conceived of packet switching in 1965 at the National Physical Laboratory (NPL) and proposed building a national commercial data network in the UK. The Advanced Research Projects Agency (ARPA) of the U.S. Department of Defense awarded contracts in 1969 for the development of the ARPANET project, directed by Robert Taylor and managed by Lawrence Roberts. ARPANET adopted the packet switching technology proposed by Davies and Baran,[7] underpinned by mathematical work in the early 1970s by Leonard Kleinrock at UCLA. The network was built by Bolt, Beranek, and Newman. Early packet switching networks such as the NPL network, ARPANET, Merit Network, and CYCLADES researched and provided data networking in the early 1970s. ARPA projects and international working groups led to the development of protocols for internetworking, in which multiple separate networks could be joined into a network of networks, which produced various standards. Bob Kahn, at ARPA, and Vint Cerf, at Stanford University, published research in 1974 that evolved into the Transmission Control Protocol (TCP) and Internet Protocol (IP), the two protocols of the Internet protocol suite. The design included concepts from the French CYCLADES project directed by Louis Pouzin. In the early 1980s, the National Science Foundation (NSF) funded national supercomputing centers at several universities in the United States, and provided interconnectivity in 1986 with the NSFNET project, thus creating network access to these supercomputer sites for research and academic organizations in the United States. International connections to NSFNET, the emergence of architecture such as the Domain Name System, and the adoption of TCP/IP internationally on existing networks marked the beginnings of the Internet. Commercial Internet service providers (ISPs) emerged in 1989 in the United States and Australia. The ARPANET was decommissioned in 1990. Limited private connections to parts of the Internet by officially commercial entities emerged in several American cities by late 1989 and 1990.[15] The NSFNET was decommissioned in 1995, removing the last restrictions on the use of the Internet to carry commercial traffic. Research at CERN in Switzerland by British computer scientist Tim BernersLee in 1989–90 resulted in the World Wide Web, linking hypertext documents into an information system, accessible from any node on the network. Since the mid-1990s, the Internet has had a revolutionary impact on culture, commerce, and technology, including the rise of near-instant communication by electronic mail, instant messaging, voice over Internet Protocol (VoIP) telephone calls, video chat, and the World Wide Web with its discussion forums, blogs, social networking services, and online shopping sites. Increasing amounts of data are transmitted at higher and higher speeds over fiber-optic networks operating at 1 Gbit/s, 10 Gbit/s, or more. The Internet's takeover of the global communication landscape was rapid in historical terms: it only communicated 1% of the information flowing through two-way telecommunications networks in the year 1993, 51% by 2000, and more than 97% of the telecommunicated information by 2007. The Internet continues to grow, driven by ever greater amounts of online information, commerce, entertainment, and social networking services. However, the future of the global network may be shaped by regional differences.
