WebVarious differences between the FCFS and SSTF Disk Scheduling Algorithm are as follows: FCFS stands for First Come First Serve. In contrast, the SSTF stands for Shortest Seek Time First. FCFS disk scheduling algorithm is not efficient in seek movements. In contrast, the SSTF disk scheduling algorithm is very effective in seek movements. WebBefore implementing SSTF Algorithm Program in C, let us understand the working of SSTF algorithm. SSTF selects the request with the least seek time from the current head position. SSTF chooses the pending request closest to the current head position. e.g. for the same question (as in FCFS), the order of request serviced using SSTF will be:
WebMar 24, 2024 · Characteristics of SJF Scheduling: Shortest Job first has the advantage of having a minimum average waiting time among all scheduling algorithms. It is a Greedy Algorithm. It may cause starvation if shorter processes keep coming. This problem can be solved using the concept of ageing.

WebAnswered by Malli7. To store data on a disk in 512 byte blocks with the ability to detect 2 errors and correct 1 error, we can use a Reed-Solomon error-correcting code. To correct 1 error, we need t = 1 error-correcting capability, and to detect 2 errors, we need d = 2 error-detecting capability. The number of extra bits required can be ...
