Units of Information
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. Bits are usually assembled into a group of eight to form a byte. A byte contains enough information to store a single ASCII character, like "h".

Useful information (please also do your own research)
Eight bits are known as a byte.
The binary unit system is as follows:
| 8 bits | 1 byte (B) |
|---|---|
| 1,000 bytes (1,000 B) | 1 kilobyte (KB) |
| 1,000 kilobytes (1,000 KB) | 1 megabyte (MB) |
| 1,000 megabytes (1,000 MB) | 1 gigabyte (GB) |
| 1,000 gigabytes (1,000 GB) | 1 terabyte (TB) |
| 1,000 terabytes (1,000 TB) | 1 petabyte (PB) |
