What does the Program Counter (PC) do?
Think about which address the CPU will point to for the next task.
What is the purpose of the Zero Flag?
Which flag tells us about the outcome of the last arithmetic operation?
What function does the Program Counter (PC) serve in the CPU?
Focus on what the CPU uses to find its next instruction.
True or False: The Zero Flag indicates if the previous operation resulted in a non-zero value.
Think about what the Zero Flag is signaling.
Consider a situation where the last operation's result was 0, and the jump instruction follows. Describe the resulting changes in the PC.
Reflect on how a condition being met influences the PC.
Explain how a jump on zero instruction might affect a program's control flow in terms of decision-making.
Think about how decision branches in programming could utilize this type of instruction.
