Assume two secondary memory processes exist. In light of phase 1, one priority is higher than the other. Only one process can fit in main memory. How does the CPU work on it? Can you explain the whole CPU mechanism?
The benefits of using Direct Memory Access vs Interrupt Driven I/O should be compared and contrasted.
