A disk is a storage device made of flat circular plates with magnetizable surfaces. A hard disk is a disk made from a solid magnetic material and used as a storage device. A floppy disk (also called diskette) is a disk made of flexible plastic material upon which data are stored on magnetic tracks. Tracks are areas marked on the surface of a disk. A disk drive is the electronic mechanism that actually reads what is on a disk. In hard disks, the disk and the drive are built into a single unit.

A computer system

A computer system is a collection of components that work to process data. The purpose of a computer system is to make it as easy as possible for you to use computer to solve problems. A functioning computer system combines hardware elements with software elements. The hardware elements are the mechanical are the programs written for the system. Collectively these components provide a complete computer system.

Usually, a computer system requires three basic hardware items: the central processor unit, which performs all data processing, a terminal device, which helps users to communicate with their computer system and a memory storing programs and data. These three devices are the required hardware components of any computer system. Computer system includes many other devices: a printer, a scanner and a modem. These computer devices called hard ware.

A set of instructions telling a computer what to do is a program. Programs are usually written in a Programming language like Pascal, C++. etc. Applications are programs for specific tasks. Applications include: database software, spreadsheets calculations, word-processing on a word processor. To function hardware and software, a computer needs an operation system program. Some operation system require users to type in commands to tell the computer what to do. Many computers use a graphical interface or point-and-click interface such as Windows.

Some interface allow plug-and-play, the possibility of connecting new hardware of the computer without having to adjust or configure the system to take the new hardware into account: the interface program recognize the hardware automatically.
