In CHS disk geometry, which term represents the factor multiplied by 512 bytes per sector to compute disk size?

• A. number of circles x number of halves x number of sides x 512
• B. number of cylinders x number of halves x number of shims x 512
• C. number of cylinders x number of heads x number of sectors x 512
• D. number of cells x number of heads x number of sides x 512

Answer: (C)

In CHS disk geometry, disk size in bytes is the number of sectors on the disk times the 512 bytes per sector. The total number of sectors is found by multiplying the number of cylinders, the number of heads, and the number of sectors per track. So the factor you multiply 512 by is cylinders × heads × sectors per track, giving the total sectors, which then times 512 yields the disk size. The other terms (circles, halves, shims, sides, cells) don’t correspond to CHS capacity calculations.
