This collection of connected computers is referred to as a 'network'. A collection of these networks are connected together to form a huge network called the Internet. The Internet was originally devised by the military to facilitate communication between its various mainframe computers. The general idea was that if a particular node of their computer network was taken out by a nuclear bomb, messages could still get through by rerouting to another computer in the network. In the proceeding pages I will explain how these networked computers actually communicate.
Computers share and manage data similar to people.
If two computers want to 'converse', there are several specific requirements that must be satisfied.
