Detailed explanation-1: -A computer manipulates information in digital, or more precisely, binary form. A binary number has only two discrete values-zero or one. Each of these discrete values is represented by the OFF and ON status of an electronic switch called a transistor. All computers, therefore, only understand binary numbers.
Detailed explanation-2: -A switch that is “on” or “closed” passes electrical signal through it, while a switch that is “off” or “open” blocks that signal. Computer Scientists represent an “on” switch with a 1 and an “off” switch with a 0.
Detailed explanation-3: -binary code, code used in digital computers, based on a binary number system in which there are only two possible states, off and on, usually symbolized by 0 and 1.
