Explain Real Time Communications?
Real-time communications (RTC) is any mode of telecommunications in which all users can exchange information instantly or with negligible latency. In this context, the term “real-time” is synonymous with “live.”
RTC can take place in half-duplex or full duplex modes.In half-duplex RTC, data can be transmitted in both directions on a single carrier or circuit but not at the same time.
In full-duplex RTC, data can be transmitted in both directions simultaneously on a single carrier or circuit.
RTC generally refers to peer-to-peer communications, not broadcast or multicast.
Real-time communications can include
- Telephony in the conventional sense
- Mobile and cellular telephone.
- IM (instant messaging)
- VoIP (Voice over IP, also called Internet telephone).
- Live videoconference communications
