Answer:
D. be double-sided
Step-by-step explanation:
D. be double-sided
A DVD-ROM (Digital Versatile Disc - Read Only Memory) is a type of disc that is used for storing and reading digital data. It has a higher storage capacity than a CD-ROM (Compact Disc - Read Only Memory) due to several factors, including the following:
A. making the disc single-session: A single-session disc stores all of the data in a single session, rather than using multiple sessions to store data. This allows for more data to be stored on the disc.
B. make the disc more dense by packing the pits closer together: The pits on a DVD-ROM are smaller and closer together than those on a CD-ROM, allowing for more data to be stored in the same amount of space.
C. use two layers of pits: Some DVD-ROMs use two layers of pits, which allows for even more data to be stored on the disc.
D. be double-sided: While some DVD-ROMs are double-sided, this is not a factor that contributes to the higher storage capacity of a DVD-ROM compared to a CD-ROM. Instead, the higher storage capacity is due to the other factors mentioned above.
