What is Skype?
Skype is a computer program that offers a VoIP (‘Voice over Internet Protocol’) service. This lets you make calls to people all over the world via your computers or telephone and have text chats. Calls between computers are usually free, and other Skype calls are generally inexpensive. With more than 650 million registered users, Skype is by far the most popular VoIP service, and ‘skyping’ is now almost as familiar a term as ‘googling’.
