Web Conferencing is an online service by which you can hold live meetings, conferencing, presentations and trainings via the internet particularly on TCP/IP connections. You can connect to the conference either by telephone or using your computer’s speakers and microphone through a VoIP connection.
Web conferencing usually allows real time point-to-point communication as well as multi task communications from one sender to many receivers in separate locations. Depending on the service, either an application (additional software) is downloaded and installed or a web-based application is launched in the attendee’s browser. The newest open source technology for Web Conferencing is Google’s WebRTC.
