This article mainly introduces what is the goal of the computer network, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, let the editor take you to understand it.

The goal of computer network is to realize "resource sharing and information transmission". Computer network refers to a computer system that connects multiple computers with independent functions with 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.

Resource sharing

Resource sharing means that multiple users share hardware and software resources in a computer system. The main resources that end users can share in the network system include processor time, shared space, various soft devices and data resources. Resource sharing is one of the main goals of computer network.

In a network, multiple computers or multiple users in the same computer, using both hardware and software resources. Usually, the resources needed by multiple users at the same time always exceed the actual physical resources of the system, but the use of logical (or virtual) resource allocation to achieve resource sharing can better deal with this contradiction, so as to improve the efficiency of computer use. But it must be coordinated and managed by the operating system to avoid confusion. There are two main methods: unified management and distribution by the operating system, which is suitable for multi-users in the same computer system, and users notifying each other, which is suitable for the network system.

Information transmission

Information transmission is to transmit command or status information from one end to the other through the channel and be received by the other side. Including transmission and reception. There are two kinds of transmission media: wired and wireless, wired is telephone line or special cable; wireless is the use of radio, microwave and satellite technology. The information cannot be changed in the process of information transmission, and the information itself cannot be transmitted or received. There must be carriers, such as data, language, signals, etc., and there must be a common interpretation of the carrier in terms of transmission and reception.

Information transmission includes time and space transmission. The transmission of time can also be understood as the storage of information. For example, the thought of Confucius has spread to the present through books, which breaks through the limitation of time and is transmitted from ancient times to modern times. Spatial transmission, that is, what we usually call information transmission, for example, we communicate face-to-face with language, chat with phone or social tools, send e-mail and so on, it breaks through the limitation of space and transmits from one terminal to another. We mainly introduce information transmission in the field of telecommunications.

Thank you for reading this article carefully. I hope the article "what is the goal of the computer network" shared by the editor will be helpful to everyone. At the same time, I also hope that you will support and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
