What are the main functions of computer network
This article will explain in detail what are the main functions of the computer network. 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.
The main functions of computer network are "resource sharing" and "information transmission". The so-called computer network 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.
The main functions of computer network are "resource sharing" and "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 function
Computer network functions mainly include the realization of resource sharing, the rapid transmission of data information, the improvement of reliability, the provision of load balancing and distributed processing capabilities, centralized management and comprehensive information services.
Transmission of data information (data communication)
Information transmission 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.
