Note: Werner Buchholz coined this term in 1956 when he participated in the early design of the IBM Stretch computer. It mutated from the word bite to avoid any confusion with the word bit. In 1962, he described byte as "a group of bits used to encode a character, or the number of bits transmitted in parallel to and from input-output units." This move to an 8-bit byte took place in late 1956, and the size later became the standard of the System/360 operating system, announced in April 1964.
Example: The size of the computer file measured 1,140,000 bytes, slightly more than a megabyte.
