Voice Over Internet protocol (VoIP)

Voice Over Internet Protocol or VoIP for short uses Internet Protocols to communicate with one another to allow calling from one person to another. Unlike normal telephone call VoIP allows free transmission - a huge benefit in the technological world. User interfaces have been built and designed to allow even the most novice computer user to talk free to family and friends across the globe, programs such a the obvious Skype have revolutionised the way we talk to people, this privileged option to speak to someone on the other side of the world has advanced our civilization forward to what seemed impossible 20 years ago. As long as each user has a fast enough downstream speed, preferably using an ADSL or recently even a 3G signal on a smartphone device anyone can talk for free.
