- MDR (Memory Data Register): Temporary storage for instruction.
- Program Counter: Stores the memory address of the next instruction. Increments after FDE cycle.
- Accumulator: Temporarily stores data while calculations are being worked out. - 4Common CPU components and their functions are..?ALU: completes all calculations (logic or arithmetic)
