Computers are electronic machines. They communicate with the user, perform different kinds of arithmetic operations, such as addition, subtraction, division and multiplication, solve a series of logical problems and make thousands of logical decisions. Modern computers operate quickly and accurately. Every computer consists of software and hardware. Information in the form of programmes and data is called software, but the pieces of equipment that make up the computer system are known as hardware. The most important item of hardware is the CPU (Central Processing Unit). This is the electronic unit at the centre of the computer system. The brain of the computer is the processor. It does all the processing and controls all the devices in the computer system. The main memory stores all the programmes and data used by the processor. All the other devices in the computer system are known as peripherals. They include input devices, output devices and storage devices. An input device supplies information into the computer. The most commonly used input device is a keyboard. An output device such as a monitor or a printer displays the processed data. There are two types of storage devices used with computers: a primary storage device, such as RAM, and a secondary storage device, such as a hard drive. Secondary storage can be removable, internal or external.

Computer is a complex electronic machine. Its basic job is the processing of information. For this reason, computers are known as devices, which accept two kinds of information in the form of instructions. The former is called programmes and the latter is known as data.

A modern computer today performs millions of logical operations and it doesn't get tired. Sometimes it seems that computer operates like a mechanical "brain". However, it cannot do anything unless a person tells it what to do and gives it the appropriate information. Computers replace people in dull, routine tasks, but they cannot replace human beings in every sphere of life. Nowadays scientists are trying to devise the ‘Intelligent Computer’.
