What this article shares to you is about what is the three elements of the network protocol. The editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article. Let's take a look at it.

The three elements of the network protocol and their meanings: 1, semantics, explain the meaning of each part of the control information; 2, syntax, the structure and format of user data and control information, and the order in which the data appear; 3, timing, a detailed description of the sequence of events. To put it simply: semantics indicate what to do, syntax indicates what to do, and timing indicates the order in which it is done.

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

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

In order to communicate, it is stipulated that each terminal must first transform the characters of its own character set into the characters of the standard character set before entering the network for transmission, and then transform into the characters of the terminal character set after arriving at the destination terminal. Of course, for incompatible terminals, it is necessary to transform other features in addition to character set characters, such as display format, length, number of lines, screen scrolling mode and so on.

Three elements of Network Protocol and their meanings

A network protocol consists of three elements:

(1) semantic. Semantics is to explain the meaning of each part of the control information. It specifies what kind of control information needs to be sent, as well as what actions are completed and what kind of response they make.

(2) grammar. Syntax is the structure and format of user data and control information, as well as the order in which the data appears.

(3) time series. Timing is a detailed description of the sequence of events. (also known as "synchronization").

People vividly describe these three elements as: semantics indicating what to do, grammar indicating what to do, and timing indicating the order of doing.

These are the three elements of the network protocol, and the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
