Webcam is a type of ___ device in a computer system.
Web cam is an input unit device.
A webcam is a hardware camera and input device that connects to a computer and the Internet and captures either still pictures or motion video of a user or other object. Today, most webcams are either embedded into the display with laptop computers or connected to the USB or FireWire port on the computer.
A webcam is an input device because it captures a video image of the scene in front of it. It is either built in to the computer (e.g. laptop) or it is connected through an USB cable.
The term webcam is a combination of "Web" and "video camera." The purpose of a webcam is, not surprisingly, to broadcast video on the Web. Webcams are typically small cameras that either attach to a user's monitor or sit on a desk. Most webcams connect to the computer via USB, though some use a Firewire connection.
