Web-Cam: What does PC need to make it working?

your average video card and a sound card will suffice..
Biggest issue is connection speed IMO, these things still like their bandwidth

You should only need a free USB port. Webcams are generally USB connected to the PC and use very basic capture drivers that should be inherent in your operating system or provided on an installation disk.

To take stills and send them to freinds, your connection speed isn't a MAJOR issue but speed always helps. For streaming video to the web, you'll want to ensure you have a fast connection but in most casees like this, a web cam just doesn't cut the mustard. A low end webcam will provide aomewhat fuzzy pictures and poor frame rates so it is usually best if you don't expect to have video qulity but see it as more of a snap shot camera for online sharing.

Hi

Nothing is needed other than the install disk and program that came with the web cam.

Universal cam drivers do not allways work with many web cams and the programs make it easier to operate and use.
