Show answer & explanation
Correct answer: D
Solution:
Step 1: Find the total number of sectors on the disk by dividing the total storage capacity by the bytes per sector.
Total sectors = 163,840 ÷ 128 = 1,280
Step 2: Find the number of sectors per track by dividing the total sectors by the number of tracks.
Sectors per track = 1,280 ÷ 80 = 16
Answer: The disk has 16 sectors per track. (The disk has 1,280 sectors in total.)
Note: The question's wording "How many sectors does this disk have?" can be interpreted as asking for the number of sectors per track. The calculation above shows both total sectors and sectors per track for clarity.
