Internet & the World Wide Web
What is the Internet?
In the late 1960s, the United States Department of Defense (DOD) developed an experimental communication system called ARPANet. This network initially linked computer networks at U.S. military bases. It was later extended to include defense-related companies and research institutions. In the early 1980s these interconnected networks spread widely to include universities and other organizations. With the advent of personal computers, this network of networks spread rapidly worldwide. This phenomenon of expanding networks became known as the Internet.
Today, the Internet exists globally.
What is the World Wide Web?
The World Wide Web, also known as the Web, is an architectural framework for accessing hypertext documents spread out over millions of computers all over the world. Historically, the Web started in 1989 at CERN, the European Laboratory for Particle Physics. At this lab, large teams of scientists had worked together to carry out research on particle physics. These teams' members were located all over the European countries. Because of the need to share scientific documents and data, the Web was borned.
Tim Berners-Lee, the founder of the Web, proposed to link the hypertext documents for this lab in March 1989. In December 1991, a public demonstration of the Web was given at the Hypertext '91 conference in San Antonio, Texas. In February 1993, the first graphical interface browser, Mosaic was released.
