What is Skype?

Skype may be the answer to a lot of things you've always wanted but didn't know were possible. A way to talk to family members in different parts of the country for free. A way to call people abroad—on their phones or cell phones—for less money. A way to be there for important life events when you can't be there in person.
In a nutshell, Skype is a service that lets you call other Skype users anywhere in the world and talk to them for free. You can even talk to each other live over video.
How does it work?
All of this is possible through a technology called voiceover IP, or VoIP (pronounced voyp). VoIP is a method of transmitting the human voice over Internet protocol (IP) networks. Skype uses VoIP to let you make phone calls, video calls, group calls, and more over the Internet instead of using traditional phone lines.
