This article mainly introduces what are the two main technologies in network technology, which can be used for reference. Interested friends can refer to them. I hope you will gain a lot after reading this article. Let the editor take you to know about it.

The two main technologies included in network technology are computer technology and communication technology. Network technology integrates the scattered resources on the Internet into an organic whole, realizes the comprehensive sharing and organic cooperation of resources, and enables people to use the overall ability of resources transparently and obtain information on demand.

The two main technologies included in network technology are computer technology and communication technology.

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

Computer network is a collection of scattered and independent computers on the earth connected to each other according to the network protocol. The connection medium can be cable, twisted pair, optical fiber, microwave, carrier or communication satellite. Computer network has the function of sharing hardware, software and data resources, and has the ability of centralized processing, management and maintenance of shared data resources.

Computer network includes two parts: computer and network. Among them, the computer, also known as the electronic computer, is a kind of modern intelligent electronic equipment which can run according to the program and process large amounts of data automatically and at high speed. It is made up of hardware and software, and computers without an operating system are called bare metal. The common forms are desktop computer, notebook computer, large computer and so on, and the more advanced computers are biological computer, photon computer, quantum computer and so on. The network uses physical links to connect the isolated workstations or hosts together to form a data link, so as to achieve the purpose of resource sharing and communication.

The function of computer network

1. Data communication

Data communication is one of the most important functions of computer network. Data communication is a kind of communication mode and communication service which uses data transmission technology to transmit data information between two terminals according to a certain communication protocol. It can realize the data information transmission between computer and computer, computer and terminal, and terminal and terminal. It is the third largest communication service after Telegraph and telephone service. The information transmitted in data communication is expressed in the form of binary data. another feature of data communication is that it is always associated with remote information processing, which is a generalized information processing including scientific computing, process control, information retrieval and so on.

2. Resource sharing

Resource sharing is one of the main purposes for people to establish computer networks. Computer resources include hardware resources, software resources and data resources. The sharing of hardware resources can improve the utilization rate of equipment and avoid repeated investment in equipment, such as using computer networks to build network printers; the sharing of software resources and data resources can make full use of existing information resources. reduce the work in the process of software development and avoid the repeated construction of large databases.

3. Centralized management

With the development and application of computer network technology, modern office means, operation and management have changed. At present, there are many management information systems, office automation systems and so on. Through these systems, we can realize the centralized management of daily work, improve work efficiency and increase economic benefits.

4. Implement distributed processing

The development of network technology makes distributed computing possible. For large-scale projects, it can be divided into many small problems, which are completed by different computers, and then concentrated to solve the problem.

5. Load balance

Load balancing means that work is evenly distributed to each computer system on the network. The network control center is responsible for distribution and detection. When a computer is overloaded, the system will automatically transfer the load to a lighter computer system to deal with it.

Thus it can be seen that the computer network can greatly expand the function of the computer system, expand its scope of application, improve its reliability, provide convenience for users, reduce the cost and improve the ratio of performance to price.

Thank you for reading this article carefully. I hope the article "what are the two main technologies in network technology" 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!
