What are the two parts of a computer network?
I would like to share with you which two parts the computer network generally includes. I believe most people don't know much about it, so share this article for your reference. I hope you will gain a lot after reading this article. Let's learn about it together.
A computer network generally includes two parts: "resource subnet" and "communication subnet". With the continuous improvement of the computer network structure, people logically separate the data processing function from the data communication function, and call the data processing part as the resource subnet and the communication function part as the communication subnet.
A computer network generally includes two parts: "resource subnet" and "communication subnet".
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.
With the continuous improvement of the computer network structure, people logically separate the data processing function from the data communication function, and call the data processing part as the resource subnet and the communication function part as the communication subnet.
Network hosts, terminals and their ancillary devices (including hardware, system software and application software, etc.), they constitute the basic resources of the network, mainly responsible for data processing tasks, called resource subnets.
Resource subnet refers to the client system (local dispatch automation network, MIS network and local area network of substation), including users' application resources, such as servers, fault collection computers, peripherals, system software and application software.
The data processing part is called the resource subnet, and the communication part is called the communication subnet. There are two kinds of technologies used in communication subnets: one is circuit switching, the other is packet switching. The use of the latter in the automatic data processing network of civil aviation is more in line with the sudden characteristics of air traffic control data.
The resource subnet is responsible for network-wide data processing and providing resources and network services to network users, including network data processing resources and data storage resources. The network subnet is the user-oriented part of the computer network, and its main body is connected to all the main computers in the computer network and the external devices, software and shared data resources owned by these computers. All kinds of data processing devices in the network subnet include computers, intelligent terminals, disk storage and monitoring devices.
The above is all the contents of the article "what are the two parts of the computer network?" Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
