Computers are electronic devices powered by electricity, which has only two states: off, or on. |
|
Computers use the binary system that has just two digits, 0 and 1. |

0 is used to represent off, and 1 is used to represent on. |

Each of these digital values is called a bit, the abbreviation form for binary digit. |

Practically, computers process data in terms of bytes because bit is not very informative. |
