At the smallest scale in the computer, information is stored as bits and bytes. In this section, we'll learn how bits and bytes encode information.

Everything in a computer is 0's and 1's. The **bit** stores just a 0 or 1: it's the smallest building block of storage.

How many different patterns can be made with 1, 2, or 3 bits?

Number of bits | Different Patterns |
---|---|

1 | 0 1 |

2 | 00 01 10 11 |

3 | 000 001 010 011 100 101 110 111 |
