1. What happens during the fetch stage of the cycle?
The control unit works out what the instruction means
The instruction is carried out by the arithmetic logic unit
The next instruction is copied from main memory into the CPU
The result of the instruction is stored in main memory
2. What is the role of the clock in the fetch-decode-execute cycle?
It carries the address of the next instruction from the CPU to main memory
It stores the instructions that the CPU is currently working through
It sends regular signals that control the timing of the cycle
It decodes each instruction and tells the other components what to do next
