Question 1.
What does the Program Counter (PC) do?
Show hintHide hint
Think of it as a navigation tool for the CPU.
Question 2.
Which register temporarily holds data fetched from memory?
Show hintHide hint
It's called a buffer because it temporarily holds data.
3Question 3.
What is the role of the Program Counter (PC)?
- It stores instructions.
- It holds the address of the next instruction.
- It manages memory access.
Show hintHide hint
Think about its purpose during instruction execution.
4Question 4.
True or False: The Memory Buffer Register (MBR) holds the address of the next instruction.
- True
- False
Show hintHide hint
Consider what kind of information each register is responsible for.
Question 5.
Imagine a scenario where the PC and MAR operate simultaneously to fetch data. What potential resource conflicts can occur, and how would you resolve them?
Show hintHide hint
Think about the sequence of operations and the importance of timing their execution.
Question 6.
Given a hypothetical CPU with a slower memory speed, evaluate how this would affect the overall efficiency of the fetch and execution cycles.
Show hintHide hint
Consider how effectively the CPU can manage its tasks while awaiting memory operations.
