turn around time is the difference of time between the time of arrival of process and time of dispatch of process or we can say the time of completion of process
waiting time =turn around time-burst time
time complexity for Assembly line scheduling is linear.i.e O(n)
Turn around time is the time it takes to complete a set.
dynamic job shop scheduling is the scheduling of the machine it can processes different jobs at time. it switches from one job to another job. in real time process jobs are executed based on the 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.
A scheduler is the heart of every RTOS. It provides the algorithms to select the task for execution. Three common scheduling algorithms are > Cooperative scheduling > Round-robin scheduling > Preemptive scheduling RTOS uses preemptive (priority based) scheduling. In some cases, real-time requirements can be met by using static scheduling.
Facilities Scheduling is used to schedule date and time slots for facilities in order to ensure that there are no scheduling conflict between any parties and to facilitate planning.
Scheduling is necessary because a computer can only handle one task at a time.
Yes, it is one of many scheduling algorithms suitable for time sharing.However it is not suitable for scheduling in a hard realtime OS that must consistently meet deadlines.
Average Turn Around Time = Completion Time - Arrival TimeAverage Waiting Time = Turn Around Time - Burst(execution) Time
- Every Time I Turn Around - Back in Love Again was created in 1977.
The Least Slack Time scheduling algorithm is used for assigning priority based on the slack time (temporal difference between the deadline, ready time and run time) of a process.
