Question 1.
What does MDR stand for and its role?
Show hintHide hint
Think about what the data register does.
Question 2.
How many buses does a single bus architecture use?
Show hintHide hint
Remember the word 'Single'.
3Question 3.
What is the primary function of the MDR?
- To execute arithmetic operations
- To hold data temporarily from memory
- To store program instructions
Show hintHide hint
It holds data, not executes instructions.
4Question 4.
In a three-bus architecture, control signals are:
- True
- False
Show hintHide hint
They guide the data flow.
Question 5.
Explain a situation where a three-bus architecture would not be more efficient than a single bus architecture in terms of step count.
Show hintHide hint
Think of how straightforward tasks can be done quickly with less friction.
Question 6.
Design a hypothetical CPU instruction that utilizes the ALU in both single and three bus architectures. Discuss the efficiency of each.
Show hintHide hint
Map out which components interact and compare each architecture's flow.
