The
Beginning - 1960s
|
The Internet resulted from U.S. military research during the cold war
in the 1960s. They were interested in developing a system that would allow
them to communicate in the aftermath of a nuclear attack: a decentralized
network that would still function even if a section of it had been destroyed.
The research was led by the Department of Defense's Advanced Research
Project Association (ARPA) and in 1969 resulted in ARPANET, which connected
four US campuses (Stanford, UCLA, UC Santa Barbara, and the University
of Utah).

Arpanet
Expands - 1970s
|
The ARPANET continued to expand during the 1970s. Email quickly surpassed
scientific data-sharing and access to remote computers as the most popular
use of the network. USENET newsgroups were introduced in 1979.

TCP/IP
- 1980s
|
In the 1980s, TCP/IP (Transmission Control Protocol
/ Internet Protocol) was created. TCP/IP facilitates communication between
networks running over any medium: phone lines, traditional network lines,
fiber, and even cable television wires and wireless systems. It is also
computer-independent, running across IBM/compatibles, Macintoshes, or mainframe
systems. This provided all Internet computers with a standard language to
use in sending and receiving data. The loose collection of networks comprising
the ARPANET now became more cohesive and the Internet as we know it today
was born. The term "Internet" was coined in 1982. |

Internet
arrives in Canada - 1989 |
In the late 1980s, NetNorth and CDNNet emerged
in Canada, and lead to the creation in 1989 of CA*Net, funded by the National
Research Council. CA*Net is a coordinating body for 10 provincial networks

Network
of Networks - 1990s - present |
From its tiny beginnings, the Internet has become
a vast network-of-networks, made up of over 10 million inter-connected nodes
run by private businesses, government agencies, educational institutions,
and research organizations. It is accessed by countless more millions of
individuals, in virtually every country on earth, and touches almost every
aspect of our lives. |
