Try these first

1. 1.

   What does MFC stand for?

   Hint

   Think about what happens when a read operation is finished.

2. 2.

   What is the role of the Instruction Register?

   Hint

   Consider where the program's next command is stored.

3. 3.

   What is the function of the MDR?

   • It stores the next instruction
   • It holds memory data
