Detailed explanation-1: -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.
Detailed explanation-2: -In mathematics and in computing systems, a binary digit, or bit, is the smallest unit of data. Each bit has a single value of either 1 or 0, which means it can’t take on any other value. Computers can represent numbers using binary code in the form of digital 1s and 0s inside the central processing unit (CPU) and RAM.
Detailed explanation-3: -Each of those symbols represents a very specific, standardized value. In binary we’re only allowed two symbols: 0 and 1. But using those two symbols we can create any number that a decimal system can.
Detailed explanation-4: -The simplest definition of the binary number system is a system of numbering that uses only two digits-0 and 1-to represent numbers, instead of using the digits 1 through 9 plus 0 to represent numbers. To translate between decimal numbers and binary numbers, you can use a chart like the one to the left.
