This article mainly introduces the brief introduction and analysis of the computer network, which has a certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article.

Computer network refers to the system that connects distributed computer devices to achieve information transmission. 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 network (system that connects distributed computer devices for information transmission)

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.

Composition

The classification of computer network is the same as the general classification of things, which can be classified according to the different properties and characteristics of things (that is, the attributes of things). Generally speaking, a computer network is composed of multiple computers (or other computer network devices) connected together by transmission media and software physics (or logic). Generally speaking, the composition of the computer network basically includes four parts: the computer, the network operating system, the transmission medium (which can be tangible or invisible, such as the transmission medium of the wireless network is space) and the corresponding application software.

Function

Data communication

Data communication is one of the most important functions of computer network. Data communication is a kind of communication mode and communication service which uses data transmission technology to transmit data information between two terminals according to a certain communication protocol. It can realize the data information transmission between computer and computer, computer and terminal, and terminal and terminal. It is the third largest communication service after Telegraph and telephone service. The information transmitted in data communication is expressed in the form of binary data. another feature of data communication is that it is always associated with remote information processing, which is a generalized information processing including scientific computing, process control, information retrieval and so on.

Resource sharing

Resource sharing is one of the main purposes for people to establish computer networks. Computer resources include hardware resources, software resources and data resources. The sharing of hardware resources can improve the utilization rate of equipment and avoid repeated investment in equipment, such as using computer networks to build network printers; the sharing of software resources and data resources can make full use of existing information resources. reduce the work in the process of software development and avoid the repeated construction of large databases.

Centralized management

With the development and application of computer network technology, modern office means, operation and management have changed. At present, there are many management information systems, office automation systems and so on. Through these systems, we can realize the centralized management of daily work, improve work efficiency and increase economic benefits.

Implement distributed processing

The development of network technology makes distributed computing possible. For large-scale projects, it can be divided into many small problems, which are completed by different computers, and then concentrated to solve the problem.

Load balance

Load balancing means that work is evenly distributed to each computer system on the network. The network control center is responsible for distribution and detection. When a computer is overloaded, the system will automatically transfer the load to a lighter computer system to deal with it.

Thus it can be seen that the computer network can greatly expand the function of the computer system, expand its scope of application, improve its reliability, provide convenience for users, reduce the cost and improve the ratio of performance to price.
