Plug the webcam into a USB socket, turning it on if necessary, and launch the software you wish to use. There is usually an option to set the Video Source or Video Input which should show you camera along with the built-in iSight. For example; in the Skype application the camera selection is found in the Video section of the Preferences. If the camera is not recognised then software such as MacCam (See links below) will usually help.
The software being used should offer the choice of a camera source, often in a Source menu or in the preferences, so you can select between the built-in camera and other cameras attached to the computer.

The Mac mini, Mac Pro, and XServes do not have iSights, although it has been rumored that the Cinema Displays (which Apple recommends for these machines) will be updated to add iSights. Not all. a few years ago, Apple switched to Intel CPUs. Since then, all iMacs, Macbooks, and Macbook Pros come with built in iSight cameras.
The Mac's built in web cam is controlled by software so launching PhotoBooth, iChat, FaceTime or iMovie, all of which come with a Mac, will activate the camera. There are numerous other applications, such as Skype, Messenger etc., that will use the camera.

The camera doesn't have any built-in support on mac OS X, but the Macam driver project supports it. Note that you will also need other software to be able to use it in iChat.
