Question 1.
Define memory bandwidth.
Show hintHide hint
Consider how this would be important in data transfer scenarios.
Question 2.
What is latency in memory?
Show hintHide hint
Think about waiting for data.
3Question 3.
What does memory bandwidth refer to?
- The speed of the CPU
- The amount of data transferred per second
- The size of RAM
Show hintHide hint
It is often measured in gigabytes per second.
4Question 4.
True or False: Lower latency improves system responsiveness.
- True
- False
Show hintHide hint
Think about the wait time before a response occurs.
Question 5.
Given a system with a memory bandwidth of 40 GB/s and a latency of 50 ns, calculate the maximum amount of data that could be transferred in that period.
Show hintHide hint
Use the equation: Data = Bandwidth × Time.
Question 6.
Discuss how increasing the bus width from 64 bits to 128 bits while keeping latency constant would impact memory bandwidth.
Show hintHide hint
Consider how data flows on wider paths.
