eight bits

If you don't know what these are be sure to look them up: A bit is one binary digit and a byte or octet is eight bits.

'byte'

Because the term 'octet' denotes to 8 bits, whereas 'byte' refers to an undefined group of bits (usually 8 bits, but 6,7,or 10 on some computer architectures.)

8 bits (a.k.a binary digits)

The basic unit used in the computer world is the byte (a.k.a octet), a byte (or octet) has 8 bits (a.k.a binary digits).

8 bits, which can be used to represent a single letter, number or punctuation mark, or a number between 0 and 255, or anything else that can have up to 256 values

A byte or octet is 8 bits, which can be used to represent a single letter, number or punctuation mark, or a number between 0 and 255, or anything else that can have up to 256 values.

a sequence of 8 bits

A byte (or octet) is a sequence of 8 bits.

8 bits () one byte

Specifically, an octet is 8 bits (one byte), with a resulting range of [0-255].
