gradually, throughout the 1970s, universities and defense contractors working on ARPA projects began to connect to the ARPANET.

The first “node” on the ARPANET was installed at UCLA in 1969 and.

In 1966 Roberts submitted a proposal to ARPA that would allow the agency’s numerous and disparate computers to be connected in a network similar to Licklider’s Galactic Network. Roberts’ proposal was accepted, and work began on the “ ARPANET,” which would in time become what we know as today’s Internet.

Defense Department’s Advanced Research Projects Agency (ARPA). The idea was far-out at the time, but it caught the attention of Larry Roberts, a project manager at the U.S. Licklider, a professor at MIT, wrote a paper envisioning a globally connected “Galactic Network” of computers (Leiner, 2000).

Up until the mid-1960s, most computers were stand-alone machines that did not connect to or communicate with other computers.

The Web was created in 1990 by Tim Berners-Lee, a computer programmer working for the European Organization for Nuclear Research (CERN). Defense Advanced Research Agency (DARPA) in 1969 as a means for researchers and defense contractors to share information (Kahn, 2000). The Internet’s origins trace back to a project sponsored by the U.S. In fact, databases accessed via Web interfaces, make up a significant portion of the Invisible Web.

Peer-to-Peer file sharing systems, such as Napster and GnutellaĪs you see, the Internet is much more than the Web.

Other Internet protocols and interfaces include: Many of these older interfaces, or “protocols,” are still around and offer many different, unique ways of communicating with other computers (and other people). Prior to the Web, omputers could communicate with one another, but the interfaces weren’t as slick or easy to use as the Web. The Web is only about 20 years old, whereas the Internet is 50-something. You just click a link and voila: You miraculously see a page displayed on your browser screen. Is one of many interfaces to the Internet, making it easy to retrieve text, pictures, and multimedia files from computers without having to know complicated commands. The World Wide Web (Web), on the other hand, is a software protocol that runs on top of the Internet, allowing users to easily access files stored on Internet computers. It’s really nothing more than the “plumbing” that allows information of various kinds to flow from computer to computer around the world.

Is the world’s largest computer network, made up of hundreds millions of computers.

The Internet is a networking protocol (set of rules) that allows computers of all types to connect to and communicate with other computers on the Internet.
