Answer 1

You can Video chat in apps like ichat and other social networks. I use mine to Skype with my sister in England and it's really cool. You can also use it to take pictures on apps like photo booth.

Answer 2

The purpose of a webcam is to be able to send a live video of you from your computer to someone else you know along with audio.

Calling people through the internet is sometimes called VoIP (Voice Over Internet Protocol) or internet telephony.

Using a webcam requires some kind of software to operate it. The most popular is the free service Skype. You can download it from the internet for free. Using Skype you can call anyone else with Skype installed, or for a small cost you can make calls to a land-line or mobile number. There are other paid extras available like an online number, voice-mail or group calling.

If you need any more help try the Skype website for more info on video calling.
