A bit is the basic unit of computer storage. It can contain one of two values, zero or one.
A byte is 8 bits, and on most computers it is the smallest convenient chunk of storage.
- For example, most computers don’t have an instruction to move a bit but do have one to move a byte
A word is generally made up of one or more bytes.
- For example, a computer may have instructions to move 64-bit (8-byte) words.
