TEXT

Information systems collect, organize. store, process, retrieve and display information in different formats (text. video, and voice). Information technology allows very fast automated manipulation of digital data and their transformation from and to analogue,

Two basic technologies have been responsible for the development of the necessary hardware: integrated circuits and digital communications, Parallel advances have been made in software, particularly easy-to-use software products to create, maintain, manipulate, and query file-sand records. Many of these software programs are designed for use both by computer professionals and enthusiastic amateurs. Another important factor is the development of computer networks (- 6).

As technology develops, new models and types of computer appear. At the heart of all computers is the hardware. However, without software. computers are just dumb boxes, unable to perform any calculations or operations.

There are a number of models and types of computers. These are desktop, laptop, mainframe, notebook, server, terminal and workstation.

Computer hardware includes: central processing unit (CPU), dot matrix printer, expansion card, inkjet printer, keyboard, laser printer, monitor, mouse, random access memory (RAM), scanner, screen, storage devices.

Computer software includes: applet, application software, browser, database software, email software, graphics software, operating system, search engine, spreadsheet, word-processing.

The area of IT is developing very quickly. And the language to describe hardware, software and applications is also evolving at a high speed. As a result new noun+noun combinations often change to single nouns. For example, lap top has changed into laptop, note book has changed into notebook, work station has changed into workstation, desk top has changed into desktop.

By the way, many words in the sphere of IT are of American origin. So their spelling differ from the British one: programme (BrE) → program (AmE), analogue (BrE) →analog (AmE).
