For a computer with a 32-bit word length, the data length that the CPU can read and write at one time is 4 bytes. The definition of word length is "the width of the basic elements processed at one time in an operation"; however, 32-bit processors are not only able to process 32-bit data. Many data in computer applications only require 8 or 16 bits.

For a computer with a 32-bit word length, the data length that the CPU can read and write at one time is 4 bytes.
The most basic storage unit of a computer is Byte, and the smallest storage unit is bit.
A byte is composed of eight-bit binary numbers. From this, we can think that 1Byte=8bit, or that one byte and eight bits occupy the same space.
The 32-bit in the CPU refers to "word length". The definition of word length is "the width of the basic elements processed at one time in an operation." However, 32-bit processors are not only able to process 32-bit data. Many data in computer applications only require 8 or 16 bits. For example, the ASCII code commonly used in text processing only requires 8 bits, and even if unicode is used, it only requires 16 bits. Therefore, 32-bit processors basically have the ability to process shorter-digit data.
