What does the program counter (PC) do?
Think about what number tells the CPU where to look next in memory.
Name one role of the memory buffer register (MBR).
What stage does data pass through before reaching the instruction register?
What is the purpose of the program counter?
Consider which part of the CPU directs instruction flow.
The memory address register (MAR) holds what kind of information?
Isn't it always about the address during the fetch?
If the fetch cycle was executed with incorrect addresses in the program counter, how would this impact program execution?
Consider the analogy of a map: if your starting point is wrong, where would you end up?
Discuss how the performance of the fetch cycle can influence the overall speed of a CPU, especially in relation to memory speed.
How can you perform multiple tasks at once to save time?
