What are the two main technologies included in computer network technology?

The two main technologies included in computer network technology are computer technology and communication technology. Computer network includes two parts: computer and network: 1. A computer is a modern intelligent electronic device that can run according to a program and process massive amounts of data automatically and at high speed; 2. A network uses physical links to connect isolated workstations or hosts together , forming a data link to achieve the purpose of resource sharing and communication. Data communication is one of the most important functions of computer networks. It can realize the transmission of data information between computers and computers, computers and terminals, and terminals.

Computer network technology is the product of the combination of communication technology and computer technology.

A computer network is a collection of scattered and independent computers on the earth that are connected to each other according to network protocols. The connection medium may be cable, twisted pair, fiber optic, microwave, carrier wave or communications satellite. Computer networks have the function of sharing hardware, software and data resources, and have the ability to centrally process, manage and maintain shared data resources.

Computer network includes two parts: computer and network:

• The computer is also called an electronic computer, commonly known as a computer. It is a computer that can run according to a program and process massive amounts of data automatically and at high speed. Data modern smart electronic device. A computer that is composed of hardware and software and does not have an operating system installed is called a bare metal computer. Common forms include desktop computers, notebook computers, large computers, etc., and more advanced computers include biological computers, photon computers, quantum computers, etc.

• The network uses physical links to connect isolated workstations or hosts to form data links, thereby achieving the purpose of resource sharing and communication.

So computer network refers to the interconnection of multiple computer systems and their external networks in different geographical locations through communication media. The management and coordination of network operating systems, network management software and communication protocols , a system that realizes resource sharing and information transfer.

Generally speaking, a computer network is a system that interconnects computers distributed in different geographical areas with specialized external devices using communication lines to form a large-scale and powerful system, so that many computers can communicate with each other conveniently. Information, sharing hardware, software, data information and other resources. Simply put, a computer network is a collection of many autonomous computers interconnected by communication lines.

Expand knowledge: data communication

Data communication is one of the most important functions of computer networks. Data communication is a communication method and communication service that uses data transmission technology to transfer data information between two terminals according to a certain communication protocol. It can realize the transmission of data information between computers, computers and terminals, and terminals. It is the third largest communication service after telegraph and telephone services. The information transmitted in data communication is expressed in the form of binary data. Another characteristic of data communication is that it is always connected with telematics. It is a generalized information processing including scientific computing, process control, information retrieval, etc.
