Media

Item on which you store data. Disks, CD-ROMS, hard disks, magnetic

tapes are all media.

Net / Network

The interconnection of computers and other resources (printers) to share

the resources. This interconnection can be local (LAN) or global (WAN,

Internet).

Operating System

The most important program that runs on a computer. Every general-

purpose computer must have an operating system to run other programs.

Operating systems perform basic tasks, such as recognizing input from

the keyboard, sending output to the display screen, keeping track of files

and directories on the disk, and controlling peripheral devices such as

disk drives and printers.

Operating systems provide a software platform on top of which other

programs, called application programs, can run. The application

programs must be written to run on top of a particular operating system.

Your choice of operating system, therefore, determines to a great extent

the applications you can run. For PCs, the most popular operating

systems are DOS, OS/2, and Windows.

Partition

Virtual part of a hard disk that can be accessed by the operating system

as a single hard disk.
