Show hintHide hint
What does the CPU look for first?
3Question 3.
What is the purpose of the Program Counter?
- A) To hold the current status of the CPU
- B) To store the fetched instruction
- C) To point to the next instruction address
Show hintHide hint
It helps the CPU keep track of the instruction flow.
