Directions (Q91–95): A disk has a sector size of 512 bytes, 2000 tracks per surface, 50 sectors per track, five double-sided platters and an average seek time of 10 ms.
If T is the capacity of a track in bytes, and S is the capacity of each surface in bytes, then (T, S)= _____

Show answer & explanation
Correct answer: C. (25 K, 50000K)
Explanation
Track = 50 × 512 = 25,600 bytes = 25 K. Surface = 2000 tracks × 25 K = 50,000 K.
