Question

what two regions of an optical disk are translated by lasers as zeros and ones?
peaks
pits
lands
troughs
question: 7/10

Explanation:

Optical disks (like CDs, DVDs) store data using pits (indentations) and lands (flat areas). Lasers read these: pits and lands are interpreted as 0s and 1s (or vice versa) for digital data. Peaks and troughs don't apply here; pits and lands are the correct regions.

Answer:

pits, lands
