Unit 13: Internet

Notes
the laboratories of Vinton G. Cerf at Stanford University, Donald Davies (NPL), Paul
Baran (RAND Corporation), and Leonard Kleinrock at MIT and at UCLA. The research
led to the development of several packet-switched networking solutions in the late 1960s
and 1970s, including ARPANET, Telnet, and the X.25 protocols. Additionally, public
access and hobbyist networking systems grew in popularity, including unix-to-unix copy
(UUCP) and FidoNet. They were however still disjointed separate networks, served only
by limited gateways between networks. This led to the application of packet switching
to develop a protocol for internetworking, where multiple different networks could be
joined together into a super-framework of networks. By defining a simple common
network system, the Internet Protocol Suite, the concept of the network could be separated
from its physical implementation. This spread of internetworking began to form into the
idea of a global network that would be called the Internet, based on standardized
protocols officially implemented in 1982. Adoption and interconnection occurred quickly
across the advanced telecommunication networks of the western world, and then began
to penetrate into the rest of the world as it became the de-facto international standard
for the global network. However, the disparity of growth between advanced nations and
the third-world countries led to a digital divide that is still a concern.

Questions:
1. How was the Internet invented?
2. What are the benefits of Internet?
