This is because burst time of the processes can not be known in advance. While the I/O time is the time taken by the process to perform some I/O operation. 2. 3.
If we have two processes T_OLD and T_New and the actual burst time of the old process is known as 20 secs and the size of the process is 20 KB. If the process always has an actual burst time of 20, then after the first scheduling period the estimated burst value assigned to the process will be (10+20)/2 = 15. Burst-Time for any New O.S process can be predicted from any old O.S process of similar type and same for User process.

Start here for a quick overview of the site So, in this blog, we will learn about these parameters. acknowledge that you have read and understood our Detailed answers to any questions you might have The second run it will get (15+20)/2 = 17.5 estimated burst and so on. With SJF, a busy system with many short burst jobs could starve the longer burst CPU intensive jobs.
A context switch will be executed, and the process will be put at the tail of the ready queue. Then according to the simple averaging, the predicted burst time of process n+1 will be calculated as,Where, 0<=i<=n and ∑ T(i) is the summation of actual burst time of all the processes available till now.Let, Tn be the actual burst time of nth process.τ(n) be the predicted burst time for nth process then the CPU burst time for the next process (n+1) will be calculated as,Where, α is the smoothing. In a priority/quantum round robin based systems, jobs with the same priority are given at lease Thanks for contributing an answer to Computer Science Stack Exchange!

By using our site, you acknowledge that you have read and understand our Computer Science Stack Exchange is a question and answer site for students, researchers and practitioners of computer science. In general, we ignore the I/O time and we consider only the CPU time for a process. Don’t stop learning now. Similarly, the turnaround time for P3 will be 17 seconds because the waiting time of P3 is 2+5 = 7 seconds and the burst time of P3 is 10 seconds. This is because the waiting time of processes differ when we change the CPU scheduling algorithm.Throughput is a way to find the efficiency of a CPU. Computer Science Stack Exchange works best with JavaScript enabled We may not know the length of the next CPU burst, but we may be able to predict its value.
If the process always has an actual burst time of 20, then after the first scheduling period the estimated burst value assigned to the process will be (10+20)/2 = 15.
