What are the rules governing computer communication called

The rules that govern computer communication are called protocols; the communication protocol is one of the earliest protocols in the open system interconnection protocol. This protocol provides communication support for Internet networks connecting different operating systems and different hardware architectures. It is A universal language for networks, the "TCP/IP" protocol defines how information is transmitted and managed on the Internet, and sets out the rules that must be followed when errors occur.

What are the rules that govern computer communication called?

The rules that govern computer communication are called protocols.

The communication protocol is one of the earliest protocols among open system interconnection protocols. It provides communication support for interconnecting networks connecting different operating systems and different hardware architectures. It is a universal language for networks. The TCP/IP protocol defines how to transmit and manage information (file transfer, sending and receiving emails, remote login, etc.) in the Internet, and establishes the rules that must be followed when errors occur.

TCP/IP is the basic communication protocol used in the network. Although from the name TCP/IP includes two protocols, Transmission Control Protocol (TCP) and Internet Protocol (IP), TCP/IP is actually a set of protocols, which includes hundreds of protocols with various functions, such as: Remote login, file transfer and email, etc., and TCP protocol and IP protocol are two basic and important protocols to ensure the complete transmission of data. It is usually said that TCP/IP is the Internet protocol suite, not just TCP and IP.

Extended knowledge

TCP/IP (Transmission Control Protocol/Internet Protocol, Transmission Control Protocol/Internet Protocol) It refers to a protocol suite that can realize information transmission between multiple different networks. TCP/IP protocol not only refers to the two protocols TCP and IP, but refers to a protocol cluster composed of FTP, SMTP, TCP, UDP, IP and other protocols, just because in the TCP/IP protocol, the TCP protocol and IP protocol The most representative, so it is called TCP/IP protocol.

TCP/IP transmission protocol, namely transmission control/network protocol, is also called network communication protocol. It is the most basic communication protocol used in networks. The TCP/IP transport protocol stipulates the standards and methods for communication between various parts of the Internet. Moreover, TCP/IP transmission protocols are two important protocols that ensure timely and complete transmission of network data information. The TCP/IP transmission protocol is strictly a four-layer architecture, including the application layer, transport layer, network layer and data link layer.

TCP/IP protocol is the most basic protocol of the Internet. The main protocols of the application layer include Telnet, FTP, SMTP, etc., which are used to receive data from the transport layer or transmit data according to different application requirements and methods. to the transport layer; the main protocols of the transport layer are UDP and TCP, which are the channels through which users use the platform and the internal data of the computer information network to realize data transmission and data sharing; the main protocols of the network layer are ICMP, IP, and IGMP. Responsible for the transmission of data packets in the network; and the network access layer, also called the network interface layer or data link layer, the main protocols are ARP, RARP, the main function is to provide link management error detection, information details related to different communication media Perform effective processing, etc.
