History and Overview of the Internet

The Internet serves as a global system of interconnected computer networks using the TCP/IP protocol.

ARPANET was the first computer network developed in 1969 for U.S. defense forces.

The first email was sent by Tomlinson in 1972, containing meaningless letters 'QUERTYIOP'.
