Questions and Answers

What does flow control in network protocols ensure?

Ensures data flows at an efficient rate

What is message encoding in computer protocols?

Message encoding is the process of converting information into another acceptable form for transmission.

What does unicast communication refer to?

Communication between a single sender and a single receiver
