What are the rules established for data exchange in the network? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

Network protocols are the rules established by the exchange of data in the network.

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.

A network protocol refers to a collection of rules that must be followed when exchanging information between peer entities that communicate with each other in a computer network.

Peer entities usually refer to information units at the same level in the computer network architecture. The general system network protocol consists of five parts: communication environment, transmission service, vocabulary, coding format of information, timing, rules and process. When the United States Department of Defense established the earliest network, the Arpa computer Network, in 1969, it issued a set of military standards for computer communication protocols, which included five protocols. It is customary to take TCP and IP protocols as the general name of this set of protocols.

Network protocol

TCP/IP is the formal network protocol of the Internet and a group of protocols that provide interconnection functions among many independent host systems. It standardizes the transmission, interpretation, execution and interoperation of all computers on the Internet, and solves the interconnection, interoperability and operation of computer systems. It is recognized as the international industrial standard of network communication protocols. TCP/IP is a packet switching protocol in which information is divided into multiple packets and transmitted on the Internet. After arriving at the receiver, these packets are reassembled into the original information. In addition to TCP/IP, the commonly used network protocols are PPP, SLIP and so on.

This is the answer to the question about what the rules for data exchange in the network are. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
