A number is a byte.

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

B and bit

data storage is based on "Byte", and data transmission is mostly based on "bit" (also known as "bit"). One bit represents a or 1 (binary), and every 8 bits (bit, abbreviated as B) form one.

word

in a computer, a string of numbers is processed or operated as a whole, which is called a computer word, which is abbreviated as a word. A word is usually divided into several bytes (each byte is usually 8 bits). In memory, usually one word is stored in each cell. So every word is addressable. The length of a word is expressed in digits.

word length

The number of digits contained in each word of a computer is called word length, and the calculated word length refers to the number of binary digits it can handle at one time. Generally, the word length of a large computer is 32-64 bits, that of a small computer is 12-32 bits, and that of a microcomputer is 4-16 bits. Word length is an important factor to measure computer performance.
