Voice over Internet Protocol

1. VoIP is a group of internet protocols which provide a means of sending voice and multimedia communication over the internet rather than by publicc telephone networks.

2. Real-time communication has become more and more common, with communication by VoIP growing in popularity.

3. Any computer system which has a microphone input, speaker or headphone output and a broadband connection can be used to transmit and recieve voice communication using this system.

4. The addition of a webcam will allow multimedia transmission (the simultaneous transmission of video and audio).

5. When many users have these facilities, web meetings and conferencing can be set up.

6. The software required to run a VoIP system consists mainly of an encoding and decoding program, which is often called a coder/decoder programme (codec)

7. The codec programme is used, when necessary, to digitise an analogue voice signal, then compress it and split it into intwernet packets for transmission. It then performs the reverse and recieveing end.

8. VoIP is not only avaliable over desktop and laptop computers, but also over many other internet devices such as smartphones, one of the most popular VoIP systems is Skype.
