Previous Year Question (PYQs)



The total storage capacity of a floppy disk having $80$ tracks and storing $128$ bytes / sector is $163,840$ bytes. How many sectors does this disk have?





Solution

Total capacity $=$ Number of tracks $\times$ Number of sectors $\times$ Bytes per sector

$163840=80\times \text{Number of sectors}\times 128$

$\text{Number of sectors}=\frac{163840}{80\times128}$

$\text{Number of sectors}=16$
