Web conferencing software is invoked by all participants in a web meeting. Some technologies include software and functionality that differs for presenters and attendees. Software may run as a web browser application (often relying on Adobe Flash, Java, or WebRTC to provide the operational platform). Other web conferencing technologies require download and installation of software on each participant’s computer, which is invoked as a local application. Many web conferencing vendors provide the central connectivity and provisioning of meeting “ports” or “seats” as a hosted web service, while others allow the web conference host to install and run the software on its own local servers. Another installation option from certain vendors allows for use of a proprietary computer appliance that is installed at the hosting company’s physical location.IEEE project center chennai

Depending on the technology being used, participants may speak and listen to audio over standard telephone lines or via computer microphones and speakers. Some products allow for use of a webcam to display participants, while others may require their own proprietary encoding or externally provided encoding of a video feed (for example, from a professional video camera connected via an IEEE 1394 interface) that is displayed in the session.

In general, web conferencing is made possible by Internet technologies, particularly on TCP/IP connections. Services may allow real-timepoint-to-point communications as well as multicast communications from one sender to many receivers. It offers data streams of text based messages, voice and video chat to be shared simultaneously, across geographically dispersed locations. Applications for web conferencing include meetings, training events, lectures, or presentations, from a web-connected computer to other web-connected computers.

  • Polls and surveys (allows the presenter to conduct questions with multiple choice answers directed to the audience)
  • Screen sharing/desktop sharing/application sharing (where participants can view anything the presenter currently has shown on their screen. Some screen sharing applications allow for remote desktop control, allowing participants to manipulate the presenters screen, although this is not widely used.)
