The tracks on the disk surface are divided into invisible segments called?

Appeared in: AIIMS Nagpur NO - 2018

Explanation

On a magnetic or optical disk, data is stored in concentric circles known as tracks.
Each track is subdivided into smaller, wedge-like divisions called sectors.
This organization allows the disk controller to precisely locate and access specific blocks of data, as each sector has a unique address.

Option A: 'Surface' refers to the entire physical face of the disk platter where all tracks reside, not a subdivision of a single track.
Option C: 'Segments' is a generic term and not the specific technical name. While a sector is a type of segment, 'sector' is the precise term used in computer science for this part of a disk.
Option D: This option is incorrect because a correct answer, 'Sector', is available in the options.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Computer Hardware: Disk Storage Organization as background academic context rather than a clinical decision trigger.
Understanding basic computer terminology is essential for all professionals, including nurses, who rely on electronic health records (EHR) and other digital systems for patient care and data management.
What if the question asked for the collection of sectors that form a circular path? The answer would then be 'Track'.

How to Approach the Question

Identify the question's subject: This is a factual recall question about computer hardware components.
Analyze the key terms: The question asks how 'tracks' are divided into 'segments'.
Recall the hierarchical structure of a disk: A disk has platters, which have tracks, which are divided into sectors.
Evaluate the options against this structure. 'Sector' is the specific technical term for a segment of a track.
Eliminate the other options: 'Surface' is too broad, and 'Segments' is too generic.
