BITS and BYTES

Computers store and process data using binary numbers.

A single unit in binary is called a bit which stands for binary digit.

Computer memory is measured in bytes. One byte is made up of eight bits.

One byte can store one character.

The eight bit binary code in this byte represents the letter A

The size of a computer’s memory is normally measured in kilobytes (Kb), megabytes (Mb) or gigabytes (Gb). The table below shows some of the main units of size that we use to measure computer memory.
