Well this is kind of a stretch being in the programming section... none the less I'll try and help
how do u use a web cam?
In order to chat with people via a web cam, you just need to get a hosting program (that both of you use) so that you can both talk. There is AIM & Windows messenger that allow video chat...personally I don't think they are very good. You can also use Oovoo which is useful when you have many friends with web cams and what to chat/see all of them at once. But in my opinion the best program to use is Skype. The sound quality & video is quite good!
Well If You Want Your Webcam To Work So you Can Talk To Friends Try Windows Live Messenger or Sykpe. But There Are Also Websites You Can Share Your webcam With Other People. Sometimes if you go into "My Computer" and there should be a Video Camera Icon with " USB Video device" Next To it and that way you can access your webcam & take photos with your webcam.
