Final answer:
True, CD-RW discs are rewritable, allowing multiple instances of erasing and re-recording data, whereas CD-ROMs are not rewritable and can only be read.
Step-by-step explanation:
True, CD-RW (Compact Disc-ReWritable) discs are indeed rewritable, which means you can erase and rewrite data on them multiple times. On the other hand, CD-ROM (Compact Disc-Read Only Memory) cannot be written on or erased after the manufacturing process. Music CDs, which are typically CD-ROMs, store information digitally with a large information-storage capacity. This digital information is stored in a form of pits, recorded by a laser, on a spiral track running through the disc's surface. An infrared laser beam reads these pits as the CD spins, interpreting the scattering of the laser beam to reveal the digital pattern and thus, the encoded information.
