A web cam in the simplest definition is a camera that is in some way connected to the World Wide Web, or Internet. As you may imagine given this broad a definition, webcams can take many different forms and flavors. Started in 1991, the first webcam was pointed at the Trojan room coffee pot in the computer science department of Cambridge University.

One of the most common types of webcams are personal cameras that are connected to a home PC, which with the help of some software allow the user to share a moving image of themselves with others. Depending on the user, and the software, this image may be publicly available to the Internet at large via a directory of some sort, or only available to the user's friends who know the proper address to connect to. These cameras are typically only on when the user's computer is turned on, and they are connected to the Internet. With the rise of DSL and Cable modems users are leaving their computers on more, which is good overall for webcam watchers, however, it has other complications including speed and security.
