A system utilizing only the digits 0 and 1 functions, as a base 2 number system. A “bit” denotes any digit. A bit, the smallest data unit, in a computer is known as a bit with two values; 0 or 1. A Byte is an aggregation of eight bits.
ASCII uses a 7-bit convention for representing (normal/printing) characters and control operations. Each printing and control character is assigned a number from 0 to 127. For example, “a” is represented by decimal code 97 which is rendered as bit string 1100001.
