What is a byte?
A byte is 8 bits. A bit is short for binary digit, the smallest unit that a computer can understand, a 1 or a 0. Many computer operations forego the term bits for bytes and gauge the speed of certain operations, such as data transfer rates on the hard drive as bytes per second. A kilobyte is 1,024 bytes or 1,024 groups of 8 bits. A kilobit is only 1,024 bits.
