  1. Question 1

    Q1. A disk has 10 surfaces, 1024 tracks/surface, 512 sectors/track, and 512 bytes/sector. What is the total capacity?

    • A) 5 GB
    • B) 10 GB
    • C) 2.5 GB
    • D) 1.25 GB

    Answer: 2.5 GB

    Explanation: Total capacity = 10 * 1024 * 512 * 512 = 10 * 2^10 * 2^9 * 2^9 = 10 * 2²8 bytes = 2.5 * 2³0 bytes = 2.5 GB.
