This article is about what computer networks are. Xiaobian thinks it is quite practical, so share it with everyone for reference. Let's follow Xiaobian and have a look.

A computer network is a geographically dispersed system of multiple "autonomous computers" interconnected by software and hardware following agreed communication protocols. Computer network is a system that connects autonomous computers, terminals and their auxiliary equipment with communication equipment and communication lines distributed in different geographical locations and configures network software to realize computer resource sharing.

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

definitions, classification

by broad

Computer networks are also known as computer communication networks. The simplest definition of a computer network is a collection of interconnected, autonomous computers that share resources. According to this definition, early terminal-oriented networks were not computer networks, but only online systems (because many terminals at that time were not autonomous computers). But as hardware prices have fallen, many terminals have some intelligence, and "terminals" and "autonomous computers" have gradually lost their strict boundaries. If a microcomputer is used as a terminal, the early terminal-oriented network can also be called a computer network according to the above definition.

In addition, from the logical function point of view, 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, a computer network is defined by the existence of a network operating system that can be automatically managed for the user. It invokes resources that are invoked by users, and the entire network is transparent to users like a large computer system.

A more general definition is: the use of communication lines will be geographically dispersed, with independent functions of computer systems and communication equipment in different forms to connect, with functional network software and protocols to achieve resource sharing and information transmission system.

On the whole, computer network is to interconnect computers distributed in different geographical areas and specialized external equipment into a large-scale and powerful system with communication lines, so that many computers can easily transmit information to each other and share hardware, software, data information and other resources. Simply put, a computer network is an aggregation of autonomous computers interconnected by communication lines.

The simplest computer network consists of two computers and a link connecting them, two nodes and a link.

press the Connect

Computer network is an autonomous set of computers interconnected by lines. To be exact, it is a system that connects computers, terminals and their auxiliary equipment with communication equipment and communication lines distributed in different geographical locations, and configures network software to realize computer resource sharing.

on demand

Computer networks consist of a large number of independent but interconnected computers working together to complete computer tasks. These systems are called computer networks.
