Understanding of words

 

For a long time, I have a vague understanding of the word, and I have always stayed at school to understand the word = 2 bytes. I do not know whether different processors have different equations.

 

Occupies a separate address (memory unit number) in the memory of a computer and acts as a unit (composed of multiple bytes) A group of binary digits processed is called "word ). It refers to the data word, which is composed of several digits or bytes. A word or character is a piece of data for the computer's memory and the internal memory; a word or character is an instruction for the controller. In an electronic computer, words are processed as an integer.
The length of a word's binary digits. Word Length is one of the important signs of CPU. The longer the word length, the more effective digits the computer has, the higher the accuracy. The word length of a low-end microcomputer is 8 bits (one byte), and the word length of a high-end microcomputer is 16 bits (two bytes) and 32 bits (four bytes.

Different CPU chips
As early as 8085, 8 digits (actually 8 digits) are exactly a word.
8086 is a 16-digit (16-digit) string.
80386 ~ Pentium is a 32-bit (32-digit) four-character

The general term refers to the accuracy of the 8086 chip.
