Practice Questions
Test your understanding with targeted questions related to the topic.
Question 1
Easy
What is the value in R1 if R1 + 1 accesses memory location 2 initially?
💡 Hint: Consider how registers are indexed starting from 1.
Question 2
Easy
If R5 is initialized to 0, what will it be after adding the value at memory[2]?

Question 1
In direct addressing mode, how is memory accessed?
- Through the register value
- By fetching from multiple addresses
- Using an address offset
💡 Hint: Remember how registers directly point to memory locations.
Question 2
True or False: The effective address is always calculated by subtracting register values.
- True
- False
💡 Hint: Review the examples of address calculation.

Challenge Problems
Push your limits with challenges.
Question 1
You have an array starting at memory location 100H with values 1, 3, 5, and 7. If R1 is 2, what value will be added to R5 when executed with R5 += array[R1 + 1]?
💡 Hint: Calculate the effective memory location first.
Question 2
If a CPU operates with 8-bit data sizes, how many instructions could effectively fit in a 16-bit addressing space when split into two words?
💡 Hint: Count how many 8-bit segments fit into 16-bits.
