Question 174Asked in DSSSB TGT Computer Science, 24 Jun 2023, Shift 3 (4:30 PM)

The advantage of SSTF (Shoffest Seek Time First) is:

  1. Ahigh variance of response time as SSTF favours only some requests
  2. Boverhead to calculate seek time in advance
  3. Caverage response time decreases
  4. Dthroughput decreases
Show answerHide answer

Correct answer: (C) average response time decreases

Explanation

SSTF serves the request nearest to the current head position, which cuts total head movement and lowers average response time. A and B are its drawbacks.
