1) What do you mean by Process? prepare down the difference between a process and a program.

2) Five batch jobs A to E appear at same time. They have approximate running times 10,6,2,4 and 8 minutes. Their priorities are 3,5,2,1 and 4 respectively with 5 being highest priority. For each of the algorithm given, find out mean process turnaround time. Ignore process swapping overhead. Round Robin, Priority Scheduling, FCFS, SJF.

3) Describe Round Robin, Shortest Job First and Priority Scheduling Algorithms with suitable illustration.

4) prepare a detailed note on Schedulers.

5) Describe Real Time Scheduling.

7) What do you mean by Process State? Describe Process State Transitions.
