Question

NIMCET 2026 — Computer PYQ

NIMCET | Computer | 2026

There are 2 circular disks which have 4 surfaces in total. There are 5000 tracks, 2000 each. How much will the Reader read without moving?

Choose the correct answer:

Explanation

In disk storage systems, a "cylinder" refers to the set of all tracks located at the same radial distance across all disk surfaces.

Understanding the Concept:
- Since there are $4$ surfaces, all tracks at the same position form a cylinder.
- The read/write head assembly can access all surfaces of a cylinder simultaneously without physically moving the arm to a different track position.
- Therefore, the reader can access $1$ track per surface. With $4$ surfaces, it reads $4$ tracks.

This relationship is defined as:

$1 C y l in d er = 4 T r a c k s (o n e p er s u r f a ce)$

Therefore, the reader can read a cylinder (or 4 tracks) without moving. The correct option is (a).
