"With the maturity of computer network technology, computer network application has become an inevitable trend of computer development. With the rapid development of network technology, broadband network has become an inevitable trend.

Since the birth of1960s, computer network communication technology has developed greatly, especially since the development of1990s. As we all know, computer network communication technology is developing rapidly at an unexpected speed, and network communication technology and the Internet have gradually penetrated into every corner of people's lives and work. The information superhighway has directly extended to people's desktops. alvin toffler said in his masterpiece "The Future Study of Toffler Power Transfer": In ancient times, the strength of a country's military strength was mainly Malfa. 200 years ago, human beings entered the industrial society, and industrial productivity was improved. Since Malfa entered the1970s, a country's network knowledge access and storage capacity has become an important symbol to measure its comprehensive strength. The Clinton administration announced the national information superhighway plan in September. NLL (1994), national1information1intra-global information superhighway planning. After that, the whole world also has its own information superhighway planning, and an upsurge of internet construction has also been set off in various systems and business units in China. With the maturity of computer network technology, the application of computer network has become an inevitable trend of computer development. Our government recently proposed to build an e-government within 12000. The government plans to put some cross-century office affairs online, improve the work of the people's government, understand the supervision situation, and the people can query their own policies and regulations about the country online to enhance their consciousness of participating in and discussing state affairs. Although the traditional 10MBPS Ethernet meets the needs of users for various networks to a certain extent, it solves the problem of sharing network information resources and peripherals. However, with the rapid improvement of CPU performance, the informationization of workstation and user application software functions, the rapid increase of network transmission complexity and information, and the rapid development of multimedia technology in network applications, the transmission bandwidth of 10MBPS can no longer meet the development of computer technology, and the requirement of network transmission to high-speed broadband network technology has become an inevitable trend of network development. The application of computer R network in various fields, although the computer network communication technology is only thirty years, has been rapidly popularized and developed in this world with unprecedented strength and speed of human civilization. It is human civilization and any kind of totem, and the different rules of machine, communication and survival are enormous. It seems that it is echoing the "information" fiber and becoming the leading force to create the future society. Computer network will break the boundary between cultural consumption capacity and age and economic region, and make the future society enter a harmonious and unified exhibition circle, and human society will eventually enter an equal and shared democratic and open era. With the development of computer network communication technology, the application of computer network in social life is more and more extensive, and obtaining more information has become an indispensable part of the economy.
