Flash-memory-based MP3 players like the iPod Shuffle use solid-state memory. What advantage does solid-state memory have over a hard drive?

Solid-state memory, because there are no moving parts, allows for better reliability and no skipping. The technology is suited for listeners who don't keep lots of music on their MP3 players -- a player with a hard drive instead of solid-state memory can have anywhere from 10 to 150 times more memory storage.

Which of the following is not an example of solid-state memory?

What kind of battery do most MP3 players use?

Most MP3 players use rechargeable lithium-ion batteries, useful for their thin, lightweight size. Because they provide a lot of energy in relation to their small size, you'll also find them in laptops, PDAs and cell phones.
