Computers are used everywhere in the world nowadays. A computer is a machine that works with a number of electronic circuits. Computers receive information, do a lot of calculations on that information and give results. The information (data) given to the computer is called the input. The handling of the data inside the computer is called processing and the result it gives is called the output. The computer also has a memory or a place where it stores information. Every computer has input devices, a processor and output devices. The input devices accept the information, the processor handles and calculates it and the output devices (the terminal) give you the final result. Computers also have display screens and keyboard.
Computers are very useful in our modern life. They save time and cut routine. They are becoming so simple nowadays that a man with limited education can operate them.
