1. please describe in deatils,,. with an example

2. what role of I/O and cpu burst

3. differentiate b/w I/O and cpu burst in this question or scheduling algorithm.

4. if only I/O burst present then what reflect in answer...

5. give another example of related with I/O burst.

9. A uni-processor computer system only has two processes, both of which alternate 10 ms CPU bursts with 90 ms I/O bursts. Both the processes were created at nearly the same time. The I/O of both processes can proceed in parallel. Which of the following scheduling strategies will result in the least CPU utilitzation (over a long period of time) for this system? (a) First come first served scheduling (b) Shortest remaining time first scheduling (c) Static priority scheduling with different priorities for the two processes (d) Round robin scheduling with a time quantum of 5 ms
