Which statement is true about USB flash drives as backups?

• A. They use flash memory, are portable and lightweight, but have lower memory capacity and can be lost easily
• B. They have no moving parts and never wear out
• C. They require a constant network connection to access data
• D. They are always larger and heavier than external hard drives

Answer: (A)

USB flash drives store data in flash memory, which is non-volatile and keeps information without power. Because of their small size, they are very portable and lightweight, making them convenient as backups. However, they usually offer less storage capacity than external hard drives, so you get less space for the same cost. Their compact size also means they’re easy to misplace or lose, which is a real risk when used for backups. While they have no moving parts, flash memory has a limited number of write cycles, so they can wear out with heavy use. They don’t require a network connection to access data—you plug them in and read the files directly. And they’re generally smaller and lighter than external hard drives.
