A byte is a term first coined by Werner Buchholz in 1956 and later became more of a standard thanks to Bob Bemer and others. A byte is data equal to either seven or eight bits depending if it needs error correction (parity). You can think of a byte as one letter, for example, the letter 'h' is one byte or eight bits and the word 'hope' as four bytes or 32 bits (4*8).
When looking at the size of a file, a byte is the smallest measurement size listed in operating systems. However, because most files are bigger than 1,024 bytes (one kilobyte), most users will see small files listed in kilobytes.
A byte is spelled as "byte" and never as "bite."
How large is a byte?
The size of a byte depends on the computer hardware. Usually, it is eight bits. However, the size of a byte is not defined by any standard.
What unit comes before a byte?
A nibble (typically four bits) comes before a byte.
What unit comes after a byte?
