abstract

2 1 century is an era of information economy. As the representative technology of this era, computer network technology will develop at an extremely fast speed through continuous innovation and will go deep into people's work, life and study. Therefore, it is even more important to master this technology. Now I mainly introduce the application of some new network technologies in real life.

The Internet is 36 years old and still a work in progress.

Thirty-six years ago, computer scientists at UCLA connected two huge computers with a 15-foot gray cable, tested a new method of exchanging data through the network, and what eventually became the Internet was still under study.

University researchers are experimenting with ways to increase its capacity and speed. Programmers are trying to make web pages full of intelligence. Redesigning the network to reduce spam and security problems is under way.

At the same time, threats are looming: critics warn that commercial, legal and political pressures may hinder the innovations that have made the Internet today.

1On September 2nd, 969, graduate students such as Stephen Crocker and Vinton Cerf joined the engineering laboratory of Professor Ryan Kleinrock of UCLA. At that time, some meaningless test data flowed quietly between two computers. By 1 month, three other "nodes" had joined the fledgling network.

A few years later, e-mail appeared, a core communication protocol called TCP/IP appeared in the late 1970s, domain name system appeared in the 1980s, and 1990 appeared in the World Wide Web-now it is the second largest application after e-mail. The Internet has expanded from the initial military and educational fields to businesses and families all over the world.

Today, Crocker continues to work on the Internet, designing better collaboration tools. As the security chairman of the main internet watchdog, he is trying to protect the core addressing system from external threats.

He admits that the Internet he helped build is far from complete, and changes are brewing to meet the growing demand for multimedia. Internet providers now only "do their best" to transmit data packets. Crocker said that better guarantees are needed to prevent jumps and stuttering that are common in videos.

CERF, who now works for MCI, said that he hopes to design the Internet with built-in security functions. Companies such as Microsoft, Yahoo and AOL are currently trying to transform the network so that e-mail senders can be authenticated, which is a way to reduce the use of fake addresses to send spam.

Cerf said that many functions developed today were impossible when they were born, considering the slow computing speed and narrow Internet pipeline or bandwidth.
