Web conferencing
open-in-new
<p>Web conferencing is used as an <a href="/facts/Umbrella_term/bjxUuoRb">umbrella term</a> for various types of online <a href="/facts/Conference/UVRj4CWV">conferencing</a> and collaborative services including webinars (web seminars), <a href="/facts/Webcast/kpzVzFqg">webcasts</a>, and web meetings. Sometimes it may be used also in the more narrow sense of the peer-level web meeting context, in an attempt to disambiguate it from the other types known as collaborative sessions. </p><p>In general, web conferencing is made possible by <a href="/facts/Internet/Xw1rVvJU">Internet</a> technologies, particularly on <a href="/facts/TCP/IP/KNkxtSpw">TCP/IP</a> connections. Services may allow <a href="/facts/Real-time_text/VlkjjhY5">real-time</a> <a href="/facts/Point-to-point_(telecommunications)/RmGgN1Pj">point-to-point</a> communications as well as <a href="/facts/Multicast/D9IspSfl">multicast</a> <a href="/facts/Communication/EGEkchsT">communications</a> from one sender to many receivers. It offers data streams of <a href="/facts/Text-based/bngNtqIY">text-based</a> messages, voice and <a href="/facts/Video_chat/Ya9TMFQD">video chat</a> to be shared simultaneously, across geographically dispersed locations. Applications for web conferencing include <a href="/facts/Meeting/568WUreg">meetings</a>, training events, lectures, or <a href="/facts/Presentation/InRKd0W2">presentations</a> from a web-connected <a href="/facts/Computer/SQe1aK05">computer</a> to other web-connected computers. </p>
