Pipeline and Vector Processing Q.42
A hard disk has 63 sectors per track, 10 platters each with 2 recording surfaces and 1000 cylinders. The address of a sector is given as a triple (c, h, s), where c is the cylinder number, h is the surface number and s is the sector number. Thus, the 0th sector is addressed as (0, 0, 0), the 1st sector as (0, 0, 1), and so on.
- Option : C
- Explanation : For option
(a) sector no. = 0 * 20 * 63 + 15 * 63 + 31 = 976 sector.
(b) Sector no = 0 * 20 * 63 + 16 * 63 + 30 = 1038
(c) Sector no = 0 * 20 * 63 + 16 * 63 + 31 = 1039 sector
Hence answer is (c).
