Necessity has led to invention and now each participant sits at his own desktop and connects to other participants across the world. This can be done either with the help of the downloaded software or by typing a URL and going to the site. It is generally done with the help of Flash or Java technology.
In web conferencing the tools common to web pages and Internet communication are brought together to create an environment that would enable each and every participant to put forward his/her opinion. The tools that are used are HTML, XML, ASP, java scripts, Flash animation, Instant messaging and streaming audio and video.
Function of Software
The host invites the participants to the conference conversation and they can log in only when they type in their respective Login Id and Password, which is done for security reasons. In case the conferencing is in the internal server environment the users do not require a login id or a password since the data used in the conference is not allowed to go beyond the internal network and stays behind the firewall. Web conferencing software is traded by the vendors and the cost is calculated either by the duration of usage or by a fixed fee. Vendors as per the requirement of the organization also sell their software as a licensed product and the company can download it on their own server.
Let me tell you how a normal web conference would take place. The host would accumulate all the data that is required for the conference and then let participants know that there would be a conference at a given time. Then he/she invites the participants using the software or by e-mailing them. The participants accept the invitation and at the given time open the web conferencing software to join in on the conference. The participants can see each other in the web browser and their conversation takes place over the phone, voice chat, instant messenger or a VoIP. When the conference ends the participants and the host log off or close the browser.
