Web vs. Video conferencing--What is the Difference?

There is notable confusion associated with the terms “Web Conferencing” and “video conferencing.” They are often used interchangeably. In fact, the terms have different meanings and purposes.
 
What is video conferencing?
 
Video conferencing is the use of video and audio to connect two or more points across the Internet for two-way conferencing over distance. It requires the use of webcams or other video equipment connected to a computer and/or network and uses substantially more bandwidth than web conferencing, which usually does not include any video component. Systems might employ the use of VoIP or standard telephone lines.



What is web conferencing?
 
Web conferencing is the act of connecting several Internet points for the purpose of delivering a presentation over the web. Participants are generally engaged and interactive through applications such as chat, whiteboards and desktop sharing. In more passive instances, audience members may simply watch the presentation with minimal interaction. More specifically, a webcast is the broadcast of information, either live or delayed, over the Internet and provides no interaction while a webinar involves some discussion and interaction between the presenter and attendees. Standard or VoIP phone lines might be used to include audio components.
