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.
Tip: A byte is spelled as "byte" and never as "bite."
Byte size standard confusions
Although eight bits in a byte is typically the size of a byte, there is not an official byte standard size because of how different computers treat a "word size."
