The Von Neumann architecture relies on system buses to manage the flow of information during the Fetch-Decode-Execute (FDE) cycle.
Complete the table below by writing the correct system bus (Address Bus, Data Bus, or Control Bus) that corresponds to each description.
| Bus | Description |
|---|---|
| A bidirectional pathway that transmits the machine-code instructions fetched during the FDE cycle or the operand values written to memory during the Execute phase. | |
| A unidirectional pathway that carries binary memory addresses from the Memory Address Register (MAR) to the address decoder of the main memory. | |
| A pathway that carries command, timing, and status signals (such as read/write lines, clock pulses, and interrupt requests) from the Control Unit to other system components. |
