This article will explain in detail how computer networks communicate with each other. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Computer networks communicate with each other according to the "network protocol". Computer network refers to a computer system that connects multiple computers with independent functions in different geographical locations and their external devices through communication lines, under the management and coordination of network operating systems, network management software and network communication protocols, a computer system that realizes resource sharing and information transmission.

Computer networks communicate with each other according to the "network protocol".

Computer network is also called computer communication network. The simplest definition of a computer network is a collection of autonomous computers that are interconnected for the purpose of sharing resources. According to this definition, the early terminal-oriented network is not a computer network, but can only be called an online system (because many terminals at that time could not be regarded as autonomous computers). However, with the decline of hardware prices, many terminals have a certain degree of intelligence, so "terminals" and "autonomous computers" gradually lose strict boundaries. If a microcomputer is used as a terminal, according to the above definition, the early terminal-oriented network can also be called a computer network.

In addition, from the perspective of logical function, a computer network is a collection of computer systems that connect multiple computers with communication lines for the purpose of transmitting information. A computer network consists of transmission media and communication equipment.

From the user's point of view, the computer network is defined like this: there is a network operating system that can be managed automatically for the user. It calls the resources called by the user, and the whole network, like a large computer system, is transparent to the user.

A general definition is to use communication lines to connect geographically dispersed computer systems and communication devices with independent functions in different forms. a system that uses fully functional network software and protocols to realize resource sharing and information transmission.

On the whole, the computer network is to connect the computers distributed in different geographical areas with special external equipment into a large-scale and powerful system with communication lines, so that many computers can easily transmit information to each other. Share hardware, software, data information and other resources. To put it simply, a computer network is a collection of many autonomous computers whose communication lines are connected to each other.

The simplest computer network consists of only two computers and a link that connects them, that is, two nodes and a link.

This is the end of the article on "how computer networks communicate with each other". I hope the above content can be helpful to you, so that you can learn more knowledge. if you think the article is good, please share it for more people to see.
