Explanation:
Detailed explanation-1: -A bit is a binary digit, the smallest increment of data on a computer. A bit can hold only one of two values: 0 or 1, corresponding to the electrical values of off or on, respectively. Because bits are so small, you rarely work with information one bit at a time.
Detailed explanation-2: -In computer science and mathematics, binary is a system where numbers and values are expressed 0 or 1. Binary is base-2, meaning that it only uses two digits or bits. For computers, 1 is true or “on", and 0 is false or “off". The concept of binary and bits are based on of Boolean Algebra.
Detailed explanation-3: -A single binary digit (like “0” or “1") is called a “bit". For example 11010 is five bits long.
