Web conferencingWeb conferencing is used to conduct live meetings, training, or presentations via the internet. In a web conference, each participant sits at his or her own computer and is connected to other participants via the internet. This can be either a downloaded application on each of the attendees' computers or a web-based application where the attendees access the meeting by clicking on a link distributed by e-mail (meeting invitation) to enter the conference. A webinar is a neologism to describe a specific type of web conference. It is typically oneway, from the speaker to the audience with limited audience interaction, such as in a webcast. A webinar can be collaborative and include polling and question & answer sessions to allow full participation between the audience and the presenter. In some cases, the presenter may speak over a standard telephone line, while pointing out information being presented onscreen, and the audience can respond over their own telephones, speaker phones allowing the greatest comfort and convenience There are web conferencing technologies on the . market that have incorporated the use of VoIP audio technology, to allow for a completely web-based communication. Depending upon the provider, webinars may provide hidden or anonymous participant functionality, making participants unaware of other participants in the same meeting. For interactive online workshops web conferences are complemented by electronic meeting systems (EMS) which provide a range of online facilitation tools such as brainstorming and categorization, a range of voting methods or structured discussions, typically with optional anonymity. Typically, EMS do not provide core web conferencing f unctionality such as screen sharing or voice conferencing though some EMS can control web conferencing sessions. In the early years of the Internet, the terms "web conferencing" was often used to describe a group discussions in a message board and therefor not live. The term has evolved to refer e specifically to live or "synchronous" meetings. How Does Web Conferencing Work? Web conferencing is a service involving a virtual online meeting between two or more participants. These participants could either be within the same area or building or on the other side of the world, getting together on the Internet to discuss exchange and share resources. Through web conferences participants may be able to access a variety of features which include data and audio tra nsfers, among other things. Web conferencing enables several components for it to work in synergy. Below are tools and facilities that you may be able to make use of during a web meeting? File sharing and application sharing of desktop File sharing is the foremost feature of web conferencing. It is an effective tool that produces favorable results. When a participant shares his or her workstation to
everyone in the conference, the rest of the participants will able to view those files. By giving the control of the desktop to someone else, they can also access the files and take part in providing inputs even if they are in a remote location. White Board White boards are, to simply put, the virtual version of a boardroom white board used when there is brainstorming going on in the conference. Everyone in the virtual meeting will be able to see it. The feature comes very handy since it can be set up in such a way that everyone else can have access to add or contribute to it. Polls and Surveys This feature is very useful for feedback and responses. The surveys can be tabulate
