Binary Language of Computers

Each binary digit is known for short as a bit. One bit can only be used to represent 2 different values: 0 and 1. To represent more than two values, we need to use multiple bits. Two bits combined can be used to represent 4 different values: 0 0, 0 1, 1 0, and 1 1. Three bits can be used to represent 8 different values: 0 0 0, 0 0 1, 0 1 0, 1 0 0, 0 1 1, 1 0 1, 1 1 0 and 1 1 1. In general, 'n' bits can be used to represent 2^n different values. Consider the example of representing the decimal numbers 0 through 10. There are more than 8 unique values to represent, which will therefore require a total of 4 bits (since 3 bits can only represent 8 different values). The table shows the binary equivalent for the numbers 0 through 10. This is an example of standard binary notation, or binary code.
