Byte Guide

Bytes in Computer Science

A byte is a series of 8 bits (0s and 1s).


For a long time in the history of computing, CPUs could only process one byte at a time, thus, giving the term 8-bit computer. A byte has a value range of 0 to 255 (in decimal). 1024 bytes is one kilobyte.

Bytes are usually written as a two-digit hexadecimal number. For example, $01 is the number 1 and $0a is the number 10.
