Byte
From Sega Retro
A collection of eight bits. There are two bytes in a word and four bytes in a double-word.
Additionally, 1024 bytes make a kilobyte, 1024 kilobytes make a megabyte, 1024 megabytes make a gigabyte, 1024 gigabytes make a terabyte, etc.
A common use for a byte is to store an ASCII character.
