On the Application of Network Computer
Abstract: As a new hotspot in the information industry, grid computing will become the most direct and effective method to solve the problem of scientific engineering calculation of large data in the near future. With the further development of grid computing technology and the joint efforts of service providers, grid computing will be applied to a wider range of fields and industries. The development of grid computing will surely become another revolution of the Internet, which will have a great and far-reaching impact on the application of computer grid technology and the development of other industries.

Preface of 0
Since the birth of computer network in 1960s, computer network has developed into an indispensable part of people's daily life. People can exchange information online through the computer network, such as * * *, online chat, etc. Computer network is not only a communication platform, but also an office platform for many enterprises and units, such as online ordering, online banking and online shopping. All enterprises use computer network as a means to expand their business, which not only increases the profits of enterprises, but also facilitates people's lives. In-depth analysis and research on the concept and functional characteristics of computer network will help us to better apply computer network and create greater value.
What is a computer network?
The term "computer network" consists of computers and networks. Network is an object or a combination of objects in our traditional concept to achieve a certain purpose. This combination is called a network. Computer network integrates systems of different regions and uses with communication lines, and manages the system through a unified computer network, which can liberate the system resources from the original independent system and realize the interoperability and sharing of resources. The computer work in the computer network is relatively independent, because the computer network is composed of countless computers, and the personal computer is not limited by the computer network, and can still work independently without the network.
Two types of computer networks
2. 1 divided by the median
According to the media, it can be divided into wired networks and wireless networks. As the name implies, wired network is connected by copper cable and optical fiber to realize the function of data and information dissemination. A wireless network refers to a computer network formed by spreading virtual signals through wireless transmission media such as infrared rays or microwaves.
2.2 According to the users.
According to this classification method, computer networks can be divided into public networks and private networks. The public network is a network that everyone can use, and every computer can access it. Private network refers to the working network used within an enterprise or organization, which contains important working data and information, and external computers cannot access this private network.
2.3 according to the transmission speed
By measuring the speed of data transmission, network data can be divided into two types: high-speed network and low-speed network, both of which have their specific application scope.
3 The purpose of computer network
After the application of computer network technology, the overall efficiency of information system has been comprehensively improved and developed, and the overall construction quality of information system has been effectively guaranteed. Because computer network technology can provide strong technical support for information system, it greatly promotes the development of information system and makes it develop rapidly.
3. 1 data transmission
Computer networks can transmit data between computers and service terminals. This function is the basic function of computer network, and it is a convenient and fast communication means in essence.
3.2 Resources * * * Enjoy the Platform
Computer network provides a * * * sharing platform for resources on different computers, and people can get the resources they want on this platform, which can be used for both internal resources and external resources.
3.3 Centralized management
Computer networks can centralize and integrate computer networks in different regions so as to manage them through a unified computer operating system. This centralization of management greatly improves the efficiency of management.
3.4 Reliability
Because the computer network is composed of multiple computer processing terminals, if one computer in the computer network can't work normally, another computer in the network can replace the faulty computer to complete the work that should have been completed.
3.5 Enjoy the task * * *
Computer network not only realizes the * * * sharing of resources, but also realizes the * * * sharing of work tasks. This * * sharing is suitable for a terminal. When the work task is too heavy to be completed in time, it can be shared with other computers in the network, thus improving work efficiency.
4 the practical application of computer network
4. 1 remote video teaching
.
In order to effectively expand the scope of education and improve the overall effect of education, the construction of distance education network is realized by using computer network technology, which not only enriches the educational means, but also plays a positive role in improving the educational effect. Judging from the current implementation of the distance education system, the distance education system is becoming an important form of future education. Therefore, computer network technology has been widely used in the construction of distance education network.
Remote video teaching means that teachers teach through online video, so that teaching is not limited to the classroom, and students can study in the classroom at any time, which greatly improves the teaching quality and efficiency.
4.2 Enterprise Informatization
Because the network itself has the characteristics of fast information transmission and accurate data transmission, it has been applied to the office process by many enterprises. Many enterprises have carried out information office and information management based on network technology. Computer network can build an information-based office system in an enterprise, and all kinds of data and files can be effectively transmitted and consulted in the fastest time, which greatly improves the efficiency of office.
After the application of computer network technology, the overall efficiency of information system has been comprehensively improved and developed, and the overall construction quality of information system has been effectively guaranteed. Because computer network technology can provide strong technical support for information system, it greatly promotes the development of information system and makes it develop rapidly.
4.3 Online shopping
With the accelerated pace of life and work, people have little time to go shopping. With the emergence of online shopping, this problem has been fundamentally solved. Online shopping enables people to browse all kinds of goods without leaving home, which not only saves time, but also saves the shopping process.
5 conclusion
In today's society, all aspects of people's lives are influenced by computer networks, and computer networks have become an indispensable part of people's daily lives. I believe that in the near future, computer networks will get more practical applications and provide greater help for people's lives and offices.
