Question 1.
What does indirect addressing mean?
Show hintHide hint
Think about how addresses can point to other addresses.
Question 2.
How does register indirect addressing streamline data access?
Show hintHide hint
Consider how registers are faster than accessing memory.
3Question 3.
What is one advantage of register indirect addressing compared to indirect addressing?
- Fewer memory accesses
- Slower execution
- More complex operations
Show hintHide hint
Think about how addressing modes differ in their efficiency.
4Question 4.
True or False: Indirect addressing requires two memory accesses.
- True
- False
Show hintHide hint
Recall the sequence of actions in indirect addressing.
Question 5.
Consider the following instruction execution flow: LOAD R1, M, where M indirectly points to address X, which contains value L. Draw the control signals sequence and explain the execution time.

Outline each stage clearly in your diagram.
Question 6.
Explain a scenario in a computer program where register indirect addressing would significantly improve performance compared to indirect addressing.
Show hintHide hint
Think of looping constructs or iterative calculations.
