COMPUTERS

Computer is an electronic device that can receive a program (a set of instructions) and then carry out this program by calculating numerical information.

The modern world of high technology is possible mainly due to the development of the computer. Com­puters have opened up a new era in manufacturing by means of automation, and they have enhanced modern communication systems.

Personal computers

Personal computers are also called microcomputers or home computer. The most compact are called laptops. They are portable and work on built-in batteries.

Personal computers are designed for use at homes, schools, and offices. At home they can be used for home management (balancing the family finances, for exam­ple) and for playing computer games, watching films or listening to music. Schoolchildren can use computers for doing their homework and many schools now have com­puters for independent learning and computer-literacy studies. In the office personal computers may be used for word processing, bookkeeping, storage and handling of necessary information.

Personal computers were made possible by two tech­nical innovations in the field of microelectronics: the integrated circuit, or IС, which was developed in 1959 and the microprocessor that first appeared in 1971. The IС permitted the miniaturization of computer-memory circuits, and the microprocessor reduced the size of a computer's CPU to the size of a single silicon chip.

Because a CPU calculates, performs logical opera­tions, contains operating instructions, and manages data flows, a complete microcomputer as a separate system was designed and developed in 1974.

In 1981, IBM Company offered its own microcomputer model, the IBM PC that became a necessary tool for al­most every business. The PC's use of a 16-bit microproc­essor initiated the development of faster and more pow­erful personal computers, and its use of an operating system that was available to all other computer makers led to a standardisation of the industry.

In the mid-1980s, a number of other developments were especially important for the growth of personal com­puters. One of these was the introduction of a powerful 32-bit CPU capable of running advanced operating sys­tems at high speeds.

Another innovation was the use of conventional oper­ating systems, such as UNIX, OS/2 and Windows. The Apple Macintosh computers were the first to allow the user to select icons — graphic symbols of computer func­tions — from a display screen instead of typing com­mands. New voice-controlled systems are now available, and users are able to use the words and syntax of spoken language to operate their personal computers.

HISTORY AND FUTURE OF THE INTERNET

The Internet technology was created by Vinton Cerf in early 1973 as part of a project headed by Robert Kahn and conducted by the Advanced Research Projects Agency, part of the United States Department of De­fence. Later Cerf made many efforts to build and stand­ardise the Internet. In 1984 the technology and the net­work were turned over to the private sector and to gov­ernment scientific agencies for further development. The growth has continued exponentially. Service-provider companies that make «gateways» to the Internet avail­able to home and business users enter the market in ever-increasing numbers. By early 1995, access was available in 180 countries and more than 30 million users used the Internet. The Internet and its technology continue to have a profound effect in promoting the exchange of in­formation, making possible rapid transactions among businesses, and supporting global collaboration among individuals and organisations. More than 100 million computers are connected via the global Internet in 2000, and even more are attached to enterprise internets. The development of the World Wide Web leads to the rapid introduction of new business tools and activities that may lead to annual business transactions on the Internet worth hundreds of billions of dollars.
