What Is a Home Computer Network?

A 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 implements resource sharing and information transfer in the network with well-functioning network software. Through the interconnection of computers, communication between computers is realized, so that functions such as information, software and equipment resources sharing and collaborative work among computer systems are realized. Its essential feature is to provide a high degree of sharing of various resources between computers to achieve Conveniently exchange information and exchange ideas.

Computer network system

Computer network system is made up of

Computer network functions:

(1) Resource sharing:

Resource sharing is based on network-based resource sharing. Many network enthusiasts do not seek benefits, and share some of their collected data resources with everyone through the platform, but with the development of the network and economic society, resource sharing is also exposed in society. Something went wrong.

1. Sharing of data and applications.

1.1 Print sharing

Elements of a computer network system:

(1) Computer system:

The network system must have a good connection with the existing system and related line transmission systems to ensure interconnection and interoperability. Interconnected systems include upper-layer application systems, lower-level DDN / FR / ISDN / FR line interfaces, optical fiber interfaces, and wiring systems. The interface interface can be divided into a transport layer interface, a network layer interface and an application layer interface.

1. Transmission layer: It is mainly the interface between the transmission equipment and the wiring system. The equipment of this computer network supports standard interfaces. Where the network equipment interface is inconsistent with the transmission layer, a transfer cable is provided.

The wiring system interface of the local area network, the switch port conforms to the standard Ethernet interface; for the public data communication network DDN / FR / ISDN / PSTN, the line terminal equipment outlets conform to the national telecommunication communication standards.

2. Network layer: interconnectivity, support standard communication protocols, and achieve unified network management

3. Application layer: Support TCP / IP protocol and provide good service quality management functions.
