How do you calculate the average waiting time and turnaround times of a operating system?
Average Turn Around Time = Completion Time - Arrival TimeAverage Waiting Time = Turn Around Time - Burst(execution) Time

c program for shortest remaining time scheduling algo
What is the average turnaround time at a restaurant?
6-12 minutes
University solved slips for third year bsc computer science?
The university solved slips for third year Bsc Computer Science are usually issued after the students satisfy the conditions set out by the examination body. The students also have to meet the conditions set out by the senate.
How do you Calculate average turnaround time for first come first served?
Example: Turnaround Time: P1 : 24, P2 : 27, P3 : 30 - Average TT: (24 + 27 + 30)/3 = 27
What is the relationship between turnaround CPU cycle time and waiting time?
turn around time is the time taken for completing a particular job. It is the sum of CPU cycle time and waiting time, as these two contribute to the total turn around time
How long is the turnaround time for an average Yale associates employee background check?
about 3 working days
Discuss how the following pairs of scheduling criteria conflict in certain settings?
• CPU utilization and response time: CPU utilization is increased if the overheads associated with context switching is minimized. The context switching overheads could be lowered by performing context switches infrequently. This could however result in increasing the response time for processes. • Average turnaround time and maximum waiting time: Average turnaround time is minimized by executing the shortest tasks first. Such a scheduling policy could however starve long-running tasks and thereby increase their waiting time. • I/O device utilization and CPU utilization: CPU utilization is maximized by running long-running CPU-bound tasks without performing context switches. I/O device utilization is maximized by scheduling I/O-bound jobs as soon as they become ready to run, thereby incurring the overheads of context switches.
What are the scheduling criteria for CPU scheduling?
CPU Scheduling Criteria: There are many scheduling algorithms and various criteria to judge their performance. Different algorithms may favor different types of processes. Some criteria are. as follows: • CPU utilization: CPU must be as busy as possible in performing different tasks. CPU utilization is more important in real-time system and multi-programmed systems. • Throughput: The number of processes executed in a specified time period is called throughput. The throughput increases .for short processes. It decreases if the size of processes is huge. • Turnaround Time: The amount of time that is needed to execute a process is called turnaround time. It is the actual job time plus the waiting time. • Waiting Time: The amount of time the process has waited is called waiting time. It is the turnaround time minus actual job time. • Response Time: The amount of time between a request is Submitted and the first response is produced is called response time. A CPU scheduling algorithm should try to maximize the following: • CPU utilization • Throughput A CPU scheduling algorithm should try to minimize the following: • Turnaround time • Waiting time • Response time by manish kumar gnit g.noida

When evaluating CPU scheduling algorithms why is average waiting time a better measure of performance than average turnaround time?
The reason what I think about it is-* The scheduling algorithms are used where there is a concept of multiprogramming which is a core concept of time-sharing systems.Thus, in these systems where there is time-sharing, there must be fairness in the time allotted to each user.* Now, waiting time is the time that an user program has to spend waiting in the ready queue for its turn. Whereas, turn around time is the time a process takes for its completion. Several of the programs are I/O bound and therefore, they just need a very-very small chunk of CPU time for initialization and then they go to device queue(for I/O operation). And now here, the role of waiting time is dominant which is exactly the measure of when these processes get this very-very small time and also as it determines that after how much time each user on system gets its turn.
Would maximising throughput necessarily mean maximising turnaround time?
No, maximising throughput does not necessarily mean maximising turnaround time. Throughput is a measure of how many operations can be performed in a period of time. Turnaround is a measure of how long it takes to perform an operation. If you optimize latency and/or overhead, you can increase throughput and decrease turnaround time. On the other hand, if you create parallel processing, you can increase throughput without decreasing turnaround.
