VoIP

Full Name

Voice over Internet Protocol

Description

VoIP is the voice over through the Internet. In this process, the voice of the speaker reaches to the receiver in the form of packets and again gets back the original form while the receiver receives it. To change the voice into packets, the voice is converted to digital form from the analog form and later, while receiving, the digital voice again gets back into the analog form. VoIP can be connected to any cell phone and also can be used in a PC environment.

Origin/Facts

In February 1995 when Vocaltec, Inc. introduced its Internet phone software. It was designed to run on a 486/33 MHz (or higher) personal computer (PC) equipped with a sound card, speakers, microphone, and modem. The software compressed the voice signal and translated it into IP packets for transmission over the Internet.
