The problem of slow devices holding up fast devices.d)
The problem of addressing more memory than the address bus can handle.Explanation
Since the system bus is a shared resource, a bus arbitration scheme is needed to decide which device gets control of the bus at any given time. This prevents data collisions and ensures orderly communication between components like the CPU, DMA controller, and other master devices.Related questions
