Term: byte

A byte is a group of eight bits representing a number from 0 to 255.

Because each bit can have a value of either zero or one, a group of eight of them can have 256 different combinations of zeros and one: from 00000000 to 11111111, and all of the values inbetween.

Bytes are typically easier to conceptualize than bits, and thus rather than writing out or displaying lengthy strings of zeros and ones, binary data is most commonly displayed as bytes.
