Skype: Skype is a voice over Internet protocol (VOIP) technology that allows you to make voice and video calls over the Internet. To do this you have to download the Skype software onto your computer and have a high speed Internet connection. You can make free voice and video calls to other Skype users anywhere in the world. You can also get a paid calling subscription to anywhere in the world or make pay-as-you-go calls depending on your calling pattern.
