Think about where the CPU's attention goes next.
Is the Memory Buffer Register used to hold instructions for execution?

Design a simple flowchart illustrating the fetch cycle from the moment the PC sends an address until the IR receives the instruction. Label each component and describe its role.
Use arrows to show the flow of data and rectangular boxes for each component.
Explain the impact of using a multi-clock cycle execution methodology compared to a single-cycle execution method concerning instruction fetching.
