In this issue, Xiaobian will bring you the elements of a network protocol, which are rich in content and analyzed and described from a professional perspective. After reading this article, I hope you can gain something.

A collection of rules, standards, or conventions established for the exchange of data in a computer network.

For example, if a microcomputer user communicates with an operator of a mainframe computer in a network, the commands entered by the operator do not recognize each other because the two data terminals use different character sets.

In order to be able to communicate, it is stipulated that each terminal must convert the characters in its own character set into the characters of the standard character set before entering the network transmission, and after reaching the destination terminal, it will be converted into the characters of the terminal character set.

Of course, for incompatible terminals, in addition to the character set characters, other characteristics need to be converted, such as display format, line length, line number, screen scrolling mode, etc.

Network protocol elements are the structure or format of data and control information.

Network protocol elements include:

(1) syntax, that is, the structure or format of data and control information;

(2) semantics, i.e., what control information needs to be sent, what actions need to be performed, and what responses need to be made;

(3) Chronology, i.e., a detailed description of the order in which events occur.

The above is what the elements of a network protocol shared by Xiaobian include. If there are similar doubts, please refer to the above analysis for understanding. If you want to know more about it, please pay attention to the industry information channel.
