Assume, you are trying to execute the following jobs with execution times and their varying arrival times are given. These jobs are run on a single processor using pre-emptive SJF algorithm. If the average waiting time of the processes is 4 millisecond, then the value of X is________. Show the equation with values that helps you to find the value of X.
Process No: J1 J2 J3 J4 J5 J6
Arrival time: 0 1 2 3 4 5
Burst Time: 7 5 3 1 2 X

Expert Solution
The given data is:
| Process No | Arrival Time | Burst Time |
| J1 | 0 | 7 |
| J2 | 1 | 5 |
| J3 | 2 | 3 |
| J4 | 3 | 1 |
| J5 | 4 | 2 |
| J6 | 5 | x |
The average waiting time of all the 6 jobs is 4 ms.
The only possible value of the 'x' is 1.
If you have any doubts reagrding this answer, please reach out through the cooment section.

The following data yields the arrival and service times that
each customer will require, for the first 13 customers at a single
server queue system (M/M/1). Upon arrival, a customer either enters
service if the server is idle or joins the waiting line. When the
server completes the work on a certain customer, the next one in
line (i.e. the one who has been waiting the longest) enters the
service. The studied period ends until the last customer leaves the...

4. Suppose that the following processes arrive for execution at
the times indicated. Each process will run for the amount of time
listed. In answering the questions, use non-preemptive scheduling,
and base all decisions on the information you have at the time the
decision must be made.
