Bits and Bytes



All the information in a computer is stored as a series of binary numbers (ones and zeros).

One digit (a one or a zero) is called a
bit:

0 1 0 0 1 0


Four bits are called a
nibble, though nobody uses this term anymore:

0100 1101 1010 1111


We call a group of eight bits a
byte:

01011101 11101011 01010101
