This page contains information about the components that make up a computer network.
Regardless of whether a network is fast or slow, wired or wireless, all networks share certain fundamental characteristics. At a minimum, there must be a computer making a request, a computer responding to a request, and a mechanism for the two of them to communicate.
Although it is possible to use a special cable to allow two computers to talk directly to each other without connecting to any other computer, most networks are designed to permit connection to the Internet as well as to any other local computers.
This series of pages introduce a typical, simple home network, with two computers, a printer, a router, and a connection to the Internet.
