Real-time system

Q: How deeply does Acing the CCNA Exam: Volume 1 Fundamentals and Protocols cover real-time system?

Defines the timing-versus-completeness tradeoff and stops short of detailed application protocols or configuration.

As explained in Acing the CCNA Exam: Volume 1 Fundamentals and Protocols

A real-time application is an application in which timely delivery of current data is more important than perfect delivery of all data.

A real-time application prioritizes fast delivery of current data over perfect delivery of every packet. Delays can matter more than small, temporary losses. section 22.2.3

Real-time applications commonly include:

Video streaming, online gaming, and voice or video calling. section 22.2.3
UDP is typically preferred because it sends data quickly with less overhead and does not wait for retransmissions. section 22.2.3
A video call may tolerate minor audio or visual degradation because delayed packets quickly become irrelevant. section 22.2.3
