Byte

In most computer systems, a byte is a unit of data that is eight binary digits long. A byte is the unit most computers use to represent a character such as a letter, number or typographic symbol. Each byte can hold a string of bits that need to be used in a larger unit for application purposes. For example, the stream of bits that constitute a visual image for a program that displays images or the string of bits that constitutes the machine code of a computer program.
