COMPUTER ORGANIZATION UNIT 1: BASIC STRUCTURE OF COMPUTERS TYPES OF COMPUTERS Desktop Computers • These are most commonly used computers in home, schools and offices. • This has → processing- & storage-units → video & audio output-units → keyboard & mouse input-units. Notebook Computers (Laptops) • This is a compact version of a personal-computer(PC) made as a portable-unit. Workstations • These have more computational-power than PC. • These are used for business data-processing. • These have large computational-power and larger storage-capacity than workstations. • These are referred to as → server at low-end and → super-computers at high end. Servers • These have large database storage-units and can also execute requests from other computers. • These are used in banks & educational institutions. • These are used for very complex numerical-calculations. • These are used in weather forecasting, aircraft design and military applications.
