    1. No. All buses eventually interface with the system bus to the CPU.

    2. Correct! The PCI Local Bus Controller is the interface between the system bus at a higher speed to the slower speed ISA bus.

    3. No. However, a VESA Local Bus Controller does interface with a system bus and controls the ISA interface to the system bus. But the question said you had a PCI bus.

    4. No. You may think of the Master Bus Controller as the interface, but I don't.
