There are 10 different processes running on a workstation. Idle processes are waiting for an input event in the input queue. Busy processes are scheduled with the Round-Robin timesharing method. Which out of the following quantum times is the best value for small response times, if the processes have a short runtime, e.g. less than 10ms ?

 

a)TQ=15ms

b)TQ=40ms

c)TQ=50ms

D)TQ=45ms

i think all will give same response tym becz all the tym quantums are larger than the burst tym of process ....so we can choose least of them i.e 15

Process Scheduling Algorithms
With the use of SRTF the execution of three processes is as follows, the process A is scheduled first and A has been running for 6 units of time, the process B arrives runs for 2 units of time, later process C arrives and completes its execution in 4 units of time. Find the minimum possible burst time of the process A and B.

CPU Scheduling Algorithms
Consider three processes, all arriving at time zero, with total execution time of l0,20and 30 units, respectively. Each process spends the first 20% of the execution time doing VO, the next 70% of the execution time doing computation and the last 10% of ... all I/O operations can be overlapped as much as possible. For what percentage of the time does the CPU remain idle?
