Which storage medium has tracks and sectors?
The correct answer is Option 4: Hard disk.
A Hard Disk Drive (HDD) stores data on spinning magnetic platters. To organize this data, the surface of each platter is physically and logically divided into a specific geometric layout:
Tracks: Concentric circular paths drawn around the platter (similar to the rings of a tree).
Sectors: Each track is broken down into smaller, pie-shaped wedges called sectors. A sector is the smallest addressable unit of storage on a hard disk, traditionally holding 512 bytes (or 4KB in newer Advanced Format drives) of data.
Why the other options are incorrect:
Pen drive (Option 1): Uses flash memory (solid-state technology) which organizes data in blocks and pages rather than physical tracks and sectors.
Primary memory / RAM (Option 2): Organizes data in a linear grid matrix using memory addresses (rows and columns).
ROM (Option 3): Is an integrated circuit chip that stores data permanently using a grid of non-volatile cells, not magnetic tracks.
