A headset is like headphones you use to listen to music, except it also includes a microphone so you can both hear and speak at the same time. Headsets usually have two jacks, one that plugs into your computer's microphone jack and the other into your headphone jack.Close

A webcam is a small camera that usually plugs into your computer's USB port. Most people put theirs on top of their monitor. Once you've plugged yours in and set it up, people can see you in real-time, full-motion video. Some webcams also have microphones built in.Close
