FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -CD-ROM, abbreviation of compact disc read-only memory, type of computer memory in the form of a compact disc that is read by optical means. A CD-ROM drive uses a low-power laser beam to read digitized (binary) data that has been encoded in the form of tiny pits on an optical disk.

Detailed explanation-2: -Input /Output Devices Good examples of an Input/ Output device are a floppy diskette drive, CD-ROM and DVD-ROM units and a hard while some devices are considered only Input or Output devices, the typical devices for communication between computers are considered to be both Input and Output.

Detailed explanation-3: -CD-ROM drives can be either internal, in which case they fit in a bay, or external, in which case they generally connect to the computer’s SCSI interface or parallel port.

Detailed explanation-4: -An external disc drive works identically to the one that used to come built into older computers, with the added convenience of being able to put it away once you’re done with your task. Use the drives below to archive your family history, or finally rip the last of your CD collection to a computer.
