Try these first

1. 1.

   What is the purpose of a control transfer instruction?

   Hint

   Think about how programs move from one instruction to the next.

2. 2.

   What does an unconditional jump do?

   Hint

   Consider the word 'unconditional'—what does it suggest?

3. 3.

   What type of instruction always directs execution to a specific address?

   • Conditional Jump
   • Unconditional Jump
   • Function Call

   Hint

   Think about the definition of 'unconditional'.

4. 4.

   True or False: Conditional jumps do not rely on any flags or conditions.

   • True
   • False

   Hint

   Reflect on how conditional statements work in programming.

5. 5.

   If the program is relocated to start at address 1000, how would you modify an unconditional jump originally set for address 3030? Assume you're maintaining offsets.

   Hint

   Consider how the offset changes with relocation of program memory.

6. 6.

   Design a small snippet of code that uses both an unconditional jump and a conditional jump. Explain how the flow of execution changes based on different inputs.

   Hint

   Think about how execution flow can differ based on conditions met or not met during runtime.
