Question 1.
What is immediate addressing?
Show hintHide hint
Think about how the instruction specifies data.
Question 2.
How does direct addressing work?
Show hintHide hint
Consider what happens when you refer to an address directly.
3Question 3.
What does immediate addressing allow?
- A. Directly loads data from memory
- B. Passes data via a pointer
- C. Contains data in the instruction
- D. None of the above
Show hintHide hint
Think about where the data comes from in this mode.
4Question 4.
Is direct addressing preferable when accessing large datasets?
- True
- False
Show hintHide hint
Consider how direct access limits flexibility.
Question 5.
Craft a small assembly code utilizing all three addressing modes: immediate, direct, and indirect. Explain the flow of how data moves.
Show hintHide hint
Break down how each instruction operates and the resulting values.
Question 6.
Explain how displacement addressing could improve the performance of a sorting algorithm that processes an array of integers.
Show hintHide hint
Consider how the array's indices and a register value can work together for efficient access.
