Web conferencing refers to a service that allows conferencing events to be shared with remote locations. In general the service is made possible by Internet technologies, particularly on TCP/IP connections. The service allows real - time point - to - point communications as well as multicast communications from one sender to many receivers. It offers information 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 short presentations from any computer.

[edit]Functionality
Some web conferencing solutions require additional software to be installed ( usually via download ) by the presenter and participants, while others eliminate this step by providing physical hardware or an appliance. [1] In general, system requirements depend on the vendor. Some web conferencing services vendors provide a complete solution while others enhance existing technologies. Most also provide a means of interfacing with email and calendaring clients in order that customers can plan an event and share information about it, in advance. A participant can be either an individual person or a group. System requirements that allow individuals within a group to participate as individuals ( e. g. when an audience participant asks a question ) depend on the size of the group. Handling such requirements is often the responsibility of the group. Most vendors also provide either a recorded copy of an event, or a means for a subscriber to record an event. Support for planning a shared event is typically integrated with calendar and email applications. The method of controlling access to an event is provided by the vendor. Additional value - added features are included as desired by vendors who provide them. Besides exceptions ( e. g. Openmeetings, TokBox, WebHuddle, BigBlueButton ) , web conferencing services do not apply free software but proprietary software, see Comparison of web conferencing software.
[edit]Etymology
The term webinar is short for Web - based Seminar, a presentation, lecture, workshop or seminar that is transmitted over the Web, specifically a portmanteau of web & seminar, to describe a specific type of web conference. Some argue that webinars might be one - way, [2] from the speaker to the audience with limited audience interaction, so one - way broadcasts are perhaps more accurately called webcasts. Webinars themselves may be more collaborative[3] 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 ( voice over Internet protocol ) 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.
[edit]Interactive Webinars
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 functionality such as screen sharing or voice conferencing though some EMS can control web conferencing sessions.
[edit]Features
Other typical features of a web conference include:[4]
Slide show presentations - where images are presented to the audience and markup tools and a remote mouse pointer are used to engage the audience while the presenter discusses slide content.
Live or Streaming video - where full motion webcam, digital video camera or multi - media files are pushed to the audience.
