What is Internet?
3. The first workable prototype of the Internet came in the late 1960s with the
creation of ARPANET, or the Advanced Research Projects Agency Network.
Originally funded by the U.S. Department of Defense, ARPANET used packet
switching to allow multiple computers to communicate on a single network.
The number of computer connected to the internet has grown exponentially, while
the number of users has risen from a handful of computer scientist to 1.5 Billion
consumers.
The network's reach has expanded beyond the United States to every corner of the
globe.
History of Internet
4. The Internet contains a wealth of knowledge that
is available instantly upon any search. Because of
this, the Internet has superseded libraries as a
source for information gathering and research.
Many teachers will now ask students to visit
specific websites to study from home, and online
encyclopedias provide masses of knowledge on
almost every topic imaginable. The variety of
sources allows students to pursue subjects in
much greater detail rather than being limited to
whatever the teacher sends home.
