ARPA, the precursor to the modern internet, went online in December 1969 connecting four major U.S. universities to provide a communications network for research, education, and government in case of a military attack disrupting normal communication systems. Electronic mail, or email, was introduced by Computer Scientist Ray Tomlinson, and the term "Internet" was first used to describe the early network as it expanded beyond ARPA and the word browser was coined, with the first being created by Tim Berners-Lee and later opened to the public as the World Wide Web.

1. ARPA (Advanced
Research Projects
Agency) goes online in
December, connecting
four major U.S.
universities. Designed for
research, education, and
government
organizations, it provides
a communications
network linking the
country in the event that
a military attack destroys
conventional
communications systems.
Electronic Mail or "Email"
was introduced by Ray
Tomlinson, a Computer
Scientist.
The word "Internet" was
first used.
Tim Berners-Lee
developed the first
internet browser and
named it
"WorldWideWeb" and
was later renamed
"Nexus".
