Skype is a computer program that can be used to make free voice calls over the
Internet to anyone else who is also using Skype. It’s free and considered easy to
download and use, and works with most
computers. Once you
download, register and install the software, you’ll need to plug in a headset, speakers or
USB phone to start using Skype. On September 12, 2005 Skype was acquired by eBay.
