How Does the Internet Work

In the mid 1960s, during the Cold War it became
necessary for a bombproof communications system.
A
concept was devised to link computers together
throughout the country.
 This
connection allowed people to stay connected to
important information even if one part of the community was
lost during an attack. This was designed as an emergency
military communications system operated by the
Department of Defense.

Governments and Universities were the only
ones linked in the beginning

How Does the Internet Work

Information does not travel directly from one place
to another, but gets broken up into separate data
packets
 This
information is labeled and sent to a unique internet
address
 This process takes place in a matter of milliseconds
