What the editor shares today is a detailed introduction of the computer network system. Maybe everyone is no stranger to the computer network system, or has never known about the computer network system. But don't worry, today the editor will explain the principle of the computer network system with the simplest description.

Computer network system is a system that uses communication equipment and lines to interconnect multiple computer systems with different geographical locations and independent functions, and uses fully functional network software to realize resource sharing and information transmission in the network. Through the interconnection of computers, the communication between computers is realized, so as to realize the sharing of information, software and equipment resources and cooperative work between computer systems. its essential feature is to provide a high degree of sharing of all kinds of resources between computers, to achieve convenient exchange of information and exchange of ideas.

The characteristics of computer network system

Computer network system is composed of network hardware and network software. In the network system, the choice of hardware plays a decisive role in the network, and the network software is a tool to tap the potential of the network. The main purpose of the establishment of ① computer network is to realize the sharing of computer resources. Computer resources mainly refer to computer hardware, software and data. ② interconnected computers are independent "autonomous computers" distributed in different geographical locations. Networked computers can provide both local and remote users with network services.

③-connected computers follow a common network protocol.

What are the functions of computer network: (1) resource sharing: resource sharing is based on network resource sharing, in which many network enthusiasts do not seek benefits and share some of their collected data resources to everyone through the platform. however, with the development of the network and economic society, resource sharing has also exposed some problems in the society. 1. Sharing of data and applications. 1.1 A print server is established in the print sharing LAN, which can provide printing services for all users of the LAN. 1.2 Mail function mail server can provide user name-based mail forwarding, distribution, CC and other services for all employees within the enterprise, and can complete convenient management, backup, deletion, recall, recovery and other work on the server. 1.3 the most common applications for network chat are Whiteboard, Netmeeting, WebEx and other applications, which can realize real-time and fast voice and video communication between users located in different physical locations. 1.4 Real-time messages, such as Yahoo IM, MSN and other applications, can be forwarded within the local area network and the Internet.

1.5 Database server is an important part of the enterprise local area network, which can realize the functions of data sharing, reducing redundancy, centralized storage and management, maintainability and security.

2. File sharing service is common in network storage. Using FTP and TFTP services, users can access the resources on the shared server conveniently and safely on the workgroup computer, and most of the ftp resources are free. 3. Resource backup with the development of network attacks and viruses, resource backup has become an indispensable part of resource sharing. Modern enterprises mostly adopt real-time and efficient resource backup mode. In order to maximize the protection of company information when the network crashes, and play the greatest role in disaster recovery. 4. Personal relationship: including customer resources, capability resources and so on. 5. Equipment. (2) data communication:

Data communication is a new way of communication produced by the combination of communication technology and computer technology. In order to transmit information between the two places, there must be a transmission channel, which can be divided into wired data communication and wireless data communication according to the different transmission media. However, they all connect the data terminal with the computer through the transmission channel, so that the data terminals in different locations can share software, hardware and information resources.
