Personal computers
Personal computers also called microcomputers or home computer. The most compact are called laptops. They are portable and work on build-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 IC, which was developed in 1959 and the microprocessor that first appeared in 1971. the IC permitted the miniaturization of computer-memory circuits, and the microprocessor reduced the size of a computers 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 PCs 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 standardization of the industry.
In the mid 1980s, a number of other developments were especially important for the growth of personal computers. 0ne 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 an 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.

Ex. 17 Read and translate the text with a dictionary:
What is hardware?
What is hardware?
Websters dictionary gives us the following definition of the hardware
the devices composing a computer system. Computer hardware can be divided into four categories:
Input hardware collects data and convert them into a form suitable for computer processing. The most common input device is a keyboard. It looks very much like a typewriter. Processing hardware directs the execution of software instructions in the computer. The most common components of processing hardware are the central processing unit and main memory.
The purpose of storage hardware is to store computer instructions and data and retrieve when needed for processing. Storage hardware stores data as electromagnetic signals. The most common ways of storing data are Hard disk, floppy disk and CD-Rom. The purpose of output hardware is to provided the user with the means to view information produced by the computer system. Information produced by the computer system. Information is in either hardcopy of softcopy form. Hardcopy output can be held in your hand, such as paper with text (word or numbers) or graphics printed on it. Softcopy output is displayed on a monitor.
