Final answer:
Comparing the available memory of a flash drive to a CD's storage capacity involves comparing two different storage technologies. Flash drives typically have a higher memory capacity compared to CDs due to their use of solid-state memory chips. CDs, on the other hand, rely on pits and lands on their surface to store digital information.
Step-by-step explanation:
The act of comparing the available memory of a flash drive to a CD's storage capacity is a comparison of two different storage technologies. A flash drive is a portable storage device that uses solid-state memory chips to store data. It typically has a higher memory capacity than a CD. On the other hand, a CD is an optical storage medium that relies on tiny pits and lands on its surface to store digital information. Although CDs used to have a larger information-storage capacity compared to other older storage technologies such as cassette tapes, they now have a smaller capacity compared to flash drives.
