What is the other name for Shortest Job First Preemptive Algorithm?
What are the 5 different states a process can be in scheduling (Look into process state
diagram)?
Shortest Job First is like Priority Scheduling with the priority based on ______ of the
process?
________ effect is the primary disadvantage of First Come First Serve Scheduling
algorithm.
How does Multi Level Feedback queue prevent starvation of processes that waits too
long in lower priority queue?
1. Other name of Shortest Job First Preemptive Algorithm is Shortest Remaining Time First (SRTF).
2. Five different states in which process can be in scheduling :
3. Shortest Job First is like Priority Scheduling with the priority based on CPU Burst Time of the process.
4. Convoy effect is the primary disadvantage of First Come First Serve Scheduling algorithm.
5. To avoid starvation of process in Multi Level Feedback queue(MLFQ),we update the priorities of processes dynamically so that they don't have to wait for long time due to large processes .
The following rule is used to update the priority of processes :

The following processes P1, P2, P3, P4 and P5 arrive at the same time (t = 0). Establish a timeline of the process scheduling for the following scheduling algorithms while also identifying start times for each process. FCFS (first come, first serve; assume order of P1, P2, P3, P4 and P5) SJF (shortest job first) Priority iv Round Robin (quantum = 1, assume order of P1, P2, P3, P4 and P5) Determine the average waiting time for each algorithm.
Given a system using the shortest-job-first algorithm for short-term scheduling and exponential averaging with α=0.5, what would be the next expected burst time for a process with burst times of 5, 8, 3, and 5, and an initial value for e1 of 10?
Given the following set of processes with corresponding execution times (in ms), arrival times and priority (1 – highest). For each scheduling algorithm: Construct a table showing which process is active and for how long until all processes are completely serviced (as done in class). Calculate the average waiting time and turnaround time. Process ID Burst (ms) Arrival time P1 9 0 P2 12 0 P3 3 0 P4 30 0 P5 20 0 P6 10 0 First Come First Serve...

Assume that you have four different processes with the following attributes: Process Arrival time. CPU Burst. I/O Burst Total CPU time A. 0 4 4 9 B 3 2 3 7 C 6 5 1 11 D 12 1 1 5 As we did in class, perform a scheduling simulation using these four processes according to the following algorithms: 1) First Come First Serve 2) Round Robin with time slice = 1 3) Round Robin with time slice = 3...
Answer the following question: A Multi Level Feedback (MLF) algorithm uses 5 priority levels. All levels are using Round Robin (RR) Scheduling algorithm with Quantum: 1 ms, 2 ms, 4 ms, 8 ms, 16 ms respectively. Processes start at highest priority (Q=1) and is down graded to the lower priority if it didn't finish within 1 quantum. The following processes are to be scheduled: Arrival Io Wait 0 3 Process P1 P2 P3 CPU Burst 2 4 15 4 1...

This assignment requires you to create simulations for different scheduling algorithms commonly employed by operating systems to achieve multiprogramming. All problems in this assignment assume the following: The simulations you will be creating are for a uniprocessor system (single CPU). Processes in these simulations will require CPU bursts of one or more time units followed by I/O bursts of one or more time units. For simplicity’s sake, when more than one process is executing its I/O burst at the same...
