WebA byte is now considered eight bits (an octet ), resulting in the possibility of 256 values (2 8 ). (The term byte once meant (and in some cases, still means) a collection of bits, typically of 5 to 32 bits, rather than only an 8-bit unit.) The prefix kilo, in conjunction with byte, may be, and has traditionally been, used, to mean 1,024 (2 10 ).
