A '''webcam''' is a [[video camera]] that feeds or [[Streaming media|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 travelling through systems such as the internet, and e-mailed as an attachment. When sent to a remote location, the video stream may be saved, viewed or on sent there. Unlike an [[IP camera]] (which connects using [[Ethernet]] or [[Wi-Fi]]), a webcam is generally connected by a [[USB]] cable, or similar cable, or built into computer hardware, such as laptops.
