What does a computer network generally include and the communication subnet?

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 and the data communication function. The data processing part is called the resource subnet, and the communication function part is called the communication subnet.

A computer network generally includes two parts: "resource subnet" and "communication subnet".

Computer network refers to the connection of multiple computers and their external devices with independent functions in different geographical locations through communication lines. The management of network operating systems, network management software and network communication protocols A computer system that realizes resource sharing and information transfer under and coordination.

With the continuous improvement of the computer network structure, people logically separate the data processing function and the data communication function. The data processing part is called the resource subnet, and the communication function part is called the communication subnet.

Network hosts, terminals and their ancillary equipment (including hardware, system software and application software, etc.), which constitute the basic resources of the network and are mainly responsible for data processing tasks, are called resource subnets.

The resource subnet refers to the user-end system (intra-office dispatch automation network, MIS network and substation LAN), including user 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 technologies used in communication subnets: one is circuit switching and the other is packet switching. The automatic data processing network of civil aviation adopts the latter, which is more in line with the bursty 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. Its main body is all the host computers connected to the computer network and the user-oriented external devices, software and shared data resources owned by these computers. Various data processing equipment in the network subnet include computers, intelligent terminals, disk storage, and monitoring equipment.
