Hardware
The purpose of storage hardware is to store computer instructions and data in a form that is relatively permanent and retrieve when needed for processing. Storage hardware serves the same basic functions as do office filing systems except that it stores data as electromagnetic signals. The most common ways of storing data are hard disk, floppy disk and CD-ROM.
Hard disk is a rigid disk coated with magnetic material, for storing programs and relatively large amounts of data. Floppy disk – thin, usually flexible plastic disk coated with magnetic material, for storing computer data and programs. CD-ROM (compact disk read-only memory) is a compact disk on which a large amount of digitized read-only data can be stored. CD-ROMs are very popular now because of the growing speed which CD-ROM drives can provide nowadays.
The purpose of output hardware is to provide the user with the means to view information produced by the computer system. Information is output in either hardcopy or softcopy form. Hardcopy output can be held in your hand, such as paper with text (word or numbers) or graphics printed on it. Softcopy output is displayed on a monitor.
Monitor is a component with a display screen for viewing computer data or television programs. Printer is a computer output device that produces a paper copy of data or graphics. Modem is an electronic device that makes possible the transmission of data to and from computer via telephone or other communication lines. Hardware comes in many configurations, depending on what the computer system is designed to do.
