31.3. Module Conclusion and Future Topics

Try these first

1. 1.

   What does the Memory Data Register (MDR) hold?

   Hint

   Consider what role it plays in data transfer.

2. 2.

   How does a single bus architecture operate?

   Hint

   Think about simplicity in data flow.

3. 3.

   What is the function of the Memory Data Register (MDR)?

   • To execute instructions
   • To hold data being transferred
   • To control signal directions

   Hint

   Remember its role in data management.

4. 4.

   True or False: Three-bus architecture always requires fewer control signals than single bus architecture.

   • True
   • False

   Hint

   Consider how complexity varies with architecture.

5. 5.

   Given an instruction that adds two numbers located in different registers, compare the execution time in both single and three-bus architectures considering control signal management.

   Hint

   Remember to consider not just time, but how tasks are managed.

6. 6.

   Consider a scenario where multiple data transfers happen simultaneously in a three-bus architecture. Discuss how this impacts the control signals versus a single bus system.

   Hint

   Think about how much more traffic control is needed at a busy intersection.
