What systems are the main systems of a computer network?

1: Computer network hardware and computer network software.

The computer network system is composed of computer system, data communication and network system software, and mainly has the following components from the hardware point of view:

1) Terminal: The equipment used by the user to access the network, such as teletypewriters, keyboard monitors, computers, etc. In the local area network, the terminal is generally served by the microcomputer, which is called the workstation, and the user shares network resources through the workstation.

2) Host: A computer system that is used for data analysis, processing, and network control, including external devices, operating systems, and other software. In the local area network, the host is generally served by a higher-end computer (such as 486 and 586 machines), called a server, which should have abundant resources, such as large-capacity hard disks, sufficient memory and various software.

3) Communication processing machine: the communication control processing machine set up between the communication line connected to the terminal and the host unit, and shares the control and management of data exchange and communication of various side differences. In the local area network, there is generally no communication processor, and the host directly undertakes the control and management tasks of communication.

4) Local line: refers to the line that connects the terminal with the node host, including concentrator or multiplexer. It is a low-speed line with low cost and efficiency.

The basic components of a computer network system ().

a.LAN and WAN.

b.Local computer networks and communication networks.

c.Communication subnets and resource subnets.

d.The server and the work of the mountain oak station are only suspicious.

Correct answer: Communication subnet and resource subnet.

As the name suggests, a computer network is interconnected by multiple computers to transmit information to each other, just like a network, called a computer network;

The simplest network is when two computers are interconnected.

Computer networks mainly include:

Hosts, servers, routers, switches, carriers.

A computer network is mainly composed of three parts: computer system, data communication system, network software and protocol.

In layman's terms, a computer network is composed of multiple computers (or other computer network equipment) that are physically (or logically) connected together through a transmission medium and software. In general, the composition of a computer network basically includes: a computer, a network operating system, a transmission medium (which can be tangible or intangible, such as the transmission medium of a wireless network is space) and the corresponding application software.

Judging from the current social development trend, learning a computer technology is a good choice, regardless of whether you are engaged in IT (Internet) related fields in the future, mastering certain computer technology will enhance your workplace value to a certain extent, and will also open up more development space for yourself.

Technology makes our lives better, and technology makes us more convenient.

There are three factors to consider in learning computer technology, one is one's own knowledge structure and ability characteristics; the second is the current technology development trend and industry development trend; The third is their own environment and job development needs. At present, the knowledge system of computer-related technology is very large, and different learning directions need to learn different content, and the requirements for learners are also different.

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

A computer network is a collection of computer systems that connect multiple computers with communication lines for the purpose of transmitting information, and a computer network consists of a transmission medium and communication equipment.

The simplest computer network consists of only two computers and a link that connects them, two nodes and one link.
