Exam-style question
Try this first
Define bandwidth, latency and protocol. Then state one way in which each term differs from bit rate.
Model answer
What a good answer should say
- Bandwidth is the capacity of a communication channel.
- Latency is the delay involved in communication.
- A protocol is a set of rules used for communication.
- Bit rate is the number of bits transmitted per second, so it measures the rate of bit transmission rather than channel capacity, delay or communication rules.
Explanation
Why this works
A complete answer gives accurate definitions of all three terms and contrasts each with bit rate. Bandwidth concerns capacity, latency concerns delay, and a protocol concerns rules; bit rate concerns the number of bits transmitted per second.
