In the early days of the Internet, websites could only store simple texts. After several years of development, images, sounds, animations, videos and even 3D technologies can be presented through the Internet. The website has gradually developed into the illustrated appearance we see now. Through dynamic web technology, users can also communicate with other users or webmasters, and some websites also provide e-mail services or online communication services.

196 1 year: Dr. leonard kleinrock of MIT published a paper on packet switching technology, which later became the standard communication mode of the Internet.

1969: The U.S. Department of Defense launched the computer network development plan "ARPANET" against nuclear attack.

197 1 year: ray Tomlinson, an engineer of BBN technology company in Cambridge, USA, developed e-mail. Since then, ARPANET technology has spread to universities and other research institutions.

1983: ARPANET announced the transition from the previous communication protocol "NCP" to the new protocol "TCP/IP".

1988: Steve Dorner, a student at the University of Illinois, USA, started to develop the e-mail software "Eudora".

199 1 year: Tim Berners-Lee, a scientist at CERN, developed the World Wide Web. He also developed an extremely simple browser (browsing software). Since then, the internet has spread to the public.

1993: Mark Andreesen, a student at the National Supercomputer Application Center of the University of Illinois, USA, and others developed a real browser mosaic. The software was later introduced to the market as Netscape Navigator. Since then, the Internet has exploded.

It is precisely because of the extensible communication protocol TCP/IP that different networks can be connected with each other. Therefore, Vinton G Cerf, a UCLA student who developed TCP/IP protocol, is even called "the father of the Internet" today.
