Terms of Networking

This is by no means a comprehensive list of the terms you should be familiar with before you begin to seriously study the Windows 2000 Professional operating system, but ensure that you at least know the basic meanings of the following:

  1. Application A program designed to perform a specific function directly for the user or for another application program. For example, word processors, database programs, graphics/drawing programs, Web browsers, e-mail programs.
  2. Audit The process of tracking network activity.
  3. Boot The process of loading an operating system into the computer's memory (RAM) so that applications can be run on it.
  4. Client A computer or program that accesses the resources of another computer or program across the network.
  5. Device A computer subsystem. For example, disk drives, printers, ports.
  6. Driver Software that allows the operating system to communicate with a device.
  7. Encryption Scrambling of data to make it unreadable so an unauthorized person cannot decipher it.
  8. Group An account that contains other accounts (called group members).
