As opposed to choosing the request with the shortest access time in conventional …
SpletThe traditional shortest access time first (SATF) algorithm greedily schedules the request that is closest to the current disk head position [ 16, 23 ]. It takes both seek and rotational latency into consideration. We now extend this algorithm for eager-writing, and we call this extension the SATF-EW algorithm.

A cache memory that has a hit rate of 0.8 has an access latency 10 ns and miss penalty 100 ns. An optimization is done on the cache to reduce the miss rate. However, the optimization results in an increase of cache access latency to 15 ns, whereas the miss penalty is not affected. The minimum hit rate (rounded off to two decimal …

No, a job being processed doesn't necessarily have the shortest remaining time. SRTF checks if there's a process in the ready queue which has less burst time to complete to do the preemption.
