Bits, bytes, words, Word length

Bit:: The data information processed by the computer is expressed in binary number encoding, and the second binary number "0" and "1" are the smallest units of information, called "bit" or bit (bit).

Byte (byte): In a computer, a "byte" (byte) is made up of several bits. The number of bits made up of bytes depends on the structure of the computer itself. Typically, a microcomputer's CPU uses 8 bits to make up a byte, which represents the code for a character. The 8 bits that make up a byte are treated as a whole. A byte is the basic unit of information stored by an electronic computer.

Bytes are the basic unit of measurement of storage space, and the memory and disk capacity of the computer are expressed in bytes.

Word: A set of binary numbers that occupy a single address (the number of memory cells) in the computer's memory and are processed as a unit (composed of one or more bytes). It is made up of several bits or bytes. For the computer and internal memory, a word or a few words is a data; for a controller, a word or a few words is an instruction. Inside the computer, the word is treated as a whole with an integer value.

A 8-bit CPU word is 8 bits, one character equals one byte, one byte can be processed at a time, and 32 bits of CPU word is 32 bits, one character equals 4 bytes, 4 bytes can be processed at a time, the CPU with the same word length of 64 bits can handle 8 bytes at a time, and one character equals 8 bytes.

The number of bytes in a computer's internal memory is the capacity of the internal memory.

Word Length: The number of bits of a binary number that a CPU can process at a time (at the same times) in a computer technology, that is, a single character.
