Question

The storage capacity of an optical disk is given by:

(a) Number of sectors * number of bytes per sector

(b) Number of sectors * 2(number of bytes per sector)

(c) Number of sectors * 3(number of bytes per sector)

(d) Number of sectors * 0.5(number of bytes per sector)

I got this question during an internship interview.

This is a very interesting question from Optical Disks in section Secondary Storage Devices of Computer Fundamentals

Answer 1

Right option is (a) Number of sectors * number of bytes per sector

To explain I would say: The storage capacity is given by the formula in option a. The most popular disk uses a disk of 5.25 inch diameter with a storage capacity of around 650 megabytes.
