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

unique internet address This process takes place in a matter of

milliseconds
