Question #1
Which of the following is used to measure the data transfer rate of a memory bus?
A. Both A and B
B. Hertz
C. Bytes per second
D. Bits per second

Correct Answer: Option A


Explanation:
Data transfer rate can be expressed in bytes per second (e.g., MB/s) or bits per second (e.g., Mbps), and the bus clock is in Hz. But the rate is typically Bps or bps.

Question #2
What is the relationship between access speed and storage capacity across the standard computer memory hierarchy?
A. Lower capacity devices always exhibit the slowest access times.
B. Access speed and capacity are completely identical metrics across all levels.
C. As storage capacity increases, the relative access speed generally decreases.
D. Devices with larger capacities always feature the fastest access speeds.

Correct Answer: Option C


Explanation:
In the memory hierarchy, the fastest options (registers, cache) are small and expensive, while large capacity options (HDDs, SSDs) are farther from the CPU and have slower access speeds.
