- World-renowned Uzbek mathematician
Odil AhmedovSoccer Midfielder Odil Ahmedov is an Uzbek international footballer, who plays for Anzhi Makhachkala. He usually plays as a central midfielder, but also played as a centre back during the 2011 Asian Cup, because of some injured defenders. 17. First scientist in math World-renowned Uzbek mathematicianRemembering one of our great ancestors, the thinker Muhammad al-Khwarizmi, we are proud of the fact that the popular words of our time, the terms "algorithm", "algebra" are directly related to this great ancestor. We look forward to being one of the founders of modern algebra. At the same time, not many people know that the mathematicians of our country are at the forefront of the world's mathematicians in this area of science. The mathematician who caused such progress is still in intensive research. When I start writing about academician Shavkat Abdullayevich Ayupov, who will most likely make a significant contribution to the development of this field, I have no doubt that I will be able to give students a decent impression of the great scientist. First of all, I would like to start by giving the main dates of the life and creative activity of academician Shavkat Abdullayevich. Because a lot of hard work is hidden on these dates. 18. IT technologies Information technology is the technology of data management and processing . Usually this term is understood as computer technology. In the field of information technology , work is carried out on the collection, storage, protection, processing and transmission of various information through computers and computer networks . The main technical means of information technology are the means of communication in addition to computer technology - telephone, teletype, telefax, etc. Although information technology has existed at different stages of human development, a distinctive feature of modern information society is that for the first time in the history of civilization, the energy expended on knowledge and production is converted into energy, raw materials and consumables. is outperforming cost, i.e., information technology is leading the way among existing new technologies. The complex of the information technology industry consists of computers, communication systems, data warehouses, knowledge warehouses and related activities. Today, information technology can be conditionally divided into "preserving, rationalizing, creating" types. The first type of technology saves labor, material resources, time. Examples of rationalization information technology are ticket booking, hotel billing systems. Creative (creative) information technologies consist of systems that produce, use, and integrate human information. The modern development and achievements of information technology show the need to inform all areas of science and human activity. Informatization of society means the use of information as a wealth of society, which ensures the development of the economy, the development of science and technology in the country, the acceleration of the process of democratization and intellectualization of society. Indeed, informing society is an objective process associated with increasing the role of intellectual activity in all spheres of human life. Informatization of the society contributes to the improvement of living standards of the people of the republic, the satisfaction of social needs, economic growth and the acceleration of scientific and technological progress. The process of informing the public can be divided into 5 main areas: Complex automation of labor, technological and production processes. Scientific research, design and production informatization. Automation of organizational and economic management. Informing the public service sector. Informing the process of education and training. . The role of computer systems in the acquisition of knowledge, ie the transmission of certain types of information, is enormous. The role of computer technology in the collection, storage, processing and use of information, regardless of its form, is determined by: First, the use of new information technologies in teaching accelerates the learning process compared to the standard (traditional) system, increases the student's interest in science, they develop creative activity, differentiated approach to knowledge, facilitates repetition, consolidation and control of knowledge, makes the student a subject of the learning process. Second, new information technologies can be used in the educational process in the following forms: · Computer lessons in teaching certain subjects; · Computer lessons - as a visual material; · In the organization of group and frontal work of students; · In the organization of students' scientific research; · In solving the problem of proper organization of students' free time from school, etc. Further increase in cocktail efficiency and increase in pharaonic levels. the reception of large amounts of multimedia information (text, graphics, video, sound, animation) can be achieved only through the use of new intellectual tools and human-machine interfaces. If there are not enough pictures of increasing labor productivity in computer science, the growth of efficiency in the whole economy can be significantly reduced. About 50 percent of all workplaces in the world today are equipped with information processing tools. Informing the public, providing them with new information technologies plays an important role in meeting people's needs for a variety of information. As a person lives in the world of information, events often turn to numbers and figures in order to establish the interconnectedness, interrelationships and essence of the processes, to find scientific answers to the complex questions arising from his life. Because of information, theory combines with practice. Theory of Practice Theory cannot exist or develop without practice. 19. Internet about Such problems were solved with the establishment of the Internet (International Information Network). The Internet is a product of the Cold War. It can be created even if it is partially damaged by nuclear shocks. The ARPANet, developed by the US Department of Defense in the early 1970s, was used as an experimental communication system. ARPANet is a communication package that allows you to automatically bypass broken communication links and exchange information between computers on the network. When the ARPANet network was first launched, information was exchanged between 4 computers via a special cable for only 2 minutes. At first, the network was considered secret. Later, when it became possible to exchange information via modem and telephone network, various enterprises and organizations were connected to this network. Thus, the network has become the Internet. The Internet is not subordinated to any organization, but states, funded by academic and educational organizations, a commercial structure, and millions of private individuals. The network is managed by an “Internet Architecture Council” set up by invited volunteers. The Internet is a collection of thousands of computer networks located around the world and connected to a single network. The exchange of information on the Internet is based on standard rules. The rules of data transmission on the Internet are called protocols (for example, TCP / IP - TRANSMISSION CONTROL PROTOCOL / INTERNET PROTOCOL). All packets are transmitted to the receiver via the IP protocol and all packets are checked for acceptance by the TCP protocol; once all packets have been received, the TCP protocol sorts them out and makes them look integrated. Thanks to the creation and development of a modem (Nayes 1979) that allows computers to send information over telephone networks, millions of people with only a personal computer and a telephone will be able to use the Internet even without special network devices. is becoming one of the most important tools of modern business in the study of the world market and the organization of trade. The Internet is not only a network of interconnections or data exchange, but also a set of existing databases that make up the world's knowledge repository. An important difference between the Internet and computers is that it can read information about itself. In 1992-93, the development of information technology made it possible to transmit visual and audio information over long distances in a short period of time, known as the World Wide Web. ldi. The aim of this project was to find effective ways to disseminate information on the Internet and to monitor its consequences. Today, the World Wide Web is one of the fastest growing areas of the Internet. In fact, the World Wide Web is part of the Internet, meaning an international spider web. 20.Mass media Download 316.03 Kb. Do'stlaringiz bilan baham: |
