Question

A magnetic disk pack has the following specifications: 16 surfaces, 128 tracks per surface, 256 sectors per track, and 512 bytes per sector. Calculate the capacity of the disk pack.

• A. 256 MB
• B. 512 MB
• C. 1024 MB
• D. 128 MB

Hint:

Multiply all factors (surfaces, tracks, sectors, and bytes) and convert to the desired unit (MB or GB) using powers of 1024.

Answer 1

The Correct Option is B

Disk capacity is calculated by the formula: Capacity = Surfaces × Tracks per surface × Sectors per track × Bytes per sector. Applying the given values, Capacity = 16 × 128 × 256 × 512 bytes. When converted to megabytes, this equals 512 MB (16 × 128 × 256 × 512 / 1024² MB).
