Real-time communications is the nearly simultaneous exchange of information on any type of telecommunications service from sender to receiver over a connection method with negligible latency.

RTC works by encoding audio, video, and text data into a digital packet stream that is then transferred over the Internet. One of the key features of RTC is ensuring data availability, allowing users to access a variety of hardware and software tools.

There are 2 types of RTC:

  • Half-duplex RTC: Data transmission can occur non-simultaneously.
  • Full-duplex RTC: Data transmission can occur simultaneously on a single circuit.

1.2. Key benefits of RTC

Immediacy: Real-time communications allows users to interact and communicate instantly.

Collaboration: RTC allows users to collaborate in real-time, which can be useful in many applications, such as video conferencing, group meetings, and online education.

Flexibility: RTC helps users communicate anytime, anywhere, flexible for people on the move or away.

Personalization: RTC allows for more personalized communication because of its ability to interact face-to-face, exchanging non-verbal signals.
