what's a webcam
A webcam is a video camera that feeds or streams its image in real time to or through a computer to a computer network. When captured by the computer, the video stream may be saved, viewed or sent on to other networks via systems such as the internet, and emailed as an attachment.
A webcam, or web camera, is the loosely used term for any camera that generates images that can be accessed by and displayed on the world wide web through a server. A webcam is essentially just a camera that is connected to a computer, either directly or wirelessly, and gathers a series of images for remote display elsewhere. Webcam technology is widely used by all sorts of people for all sorts of different reasons.
