Final answer:
The statement is true; DVDs have a higher storage capacity than CDs but are the same physical size due to the use of shorter-wavelength lasers allowing for closer data spacing.
Step-by-step explanation:
The statement that digital video discs (DVDs) have higher capacity than CD-ROMs but are the same size is True. CDs and DVDs indeed store information digitally and have a much larger information-storage capacity than old storage formats like audio and video cassette tapes or vinyl records. However, DVDs have enabled even greater storage capabilities than CDs because of the use of higher precision technology and shorter-wavelength lasers.
The data on these discs is encoded in the form of tiny pits and bumps etched on the surface of the discs which are then read by a laser in the CD or DVD player. The precision of the laser that creates these pits allows for the high density of information to be stored. DVDs take advantage of this precision even further, using a red laser with a shorter wavelength than the infrared laser used for CDs, which allows for closer spacing of data and, consequently, a higher storage capacity. Although they are both 12 centimeters in diameter, a DVD can hold significantly more data than a CD.
