CD-ROM stands for compact disc read-only memory. Unlike floppy and hard disks,

which use magnetic charges to represent 1s and 0s, optical discs use reflected light. On a

CD-ROM disc, 1s and 0s are represented by flat areas and bumpy (高低不平的) areas (called

“pits”) on its bottom surface. The CD-ROM disc is read by a laser that projects a tiny beam of

light on these areas. The amount of reflected light determines whether the area represents a 1 or a 0.
