webcam
Definition:
Webcam is short for web camera. A webcam is a tiny camera that usually attaches to a computer and is designed to capture video of the person using the computer and broadcast it over the Internet, although by no means is this the only use of a webcam. Some laptops now come with a webcam integrated into the laptop's screen casing which prevents the user from having to carry a separate webcam along with their laptop.
Webcams are commonly used in chat applications such as Windows Live Messenger or Skype such that each person chatting can actually see the person they are chatting with.
