Byte is a unit of measurement used by computer information technology to measure storage capacity. In some computer programming languages, it also represents data types and language characters. A bit segment stores 8-bit unsigned numbers, and the stored values range from 0 to 255. Like characters, variables of byte type only need to be stored in a memory space of one byte (8 bits).

Extended data:

Bytes are units of binary data. A byte is usually 8 bits long. However, some old computer structures use different lengths. To avoid confusion, words are used instead of bytes in most international documents. In most computer systems, a byte is an 8-bit long data unit, and most computers use a byte to represent a character, a number or other characters.

A byte can represent a series of binary bits. In some computer systems, four bytes represent a word, which is the unit that the computer can effectively process data when executing instructions. Some language descriptions need two bytes to represent a character, which is called a double-byte character set. Some processors can process double-byte or single-byte instructions. Bytes are usually abbreviated as "b", bits are usually abbreviated as lowercase "b", and the size of computer memory is usually expressed in bytes.
