Binary is a base-2 number system that uses two different symbols, usually 0 and 1, to represent numerical values and perform mathematical operations.
Each digit in a binary number is called a bit, which is short for binary digit.
In computers, each binary digit is stored in a tiny electronic switch called a transistor, which can be either on or off.
