What best defines a USB Flash Drive?

• A. A cloud storage service
• B. A flash memory storage device that plugs into a USB port or a computer or mobile device. Thumb drive
• C. An external hard disk
• D. A Blu-ray Disc

Answer: (B)

A USB flash drive is portable, non-volatile storage that uses flash memory and connects to devices via a USB port. Because it relies on flash memory, it holds data without power and has no moving parts, making it compact and durable. It plugs directly into a USB port on a computer or compatible mobile device and draws power from the USB connection, so no extra power source is needed. A common nickname for it is “thumb drive” due to its small size. This fits perfectly with the description of a flash memory storage device that plugs into a USB port on a computer or mobile device. It’s not cloud storage, which is data stored remotely on servers accessed over the internet. It’s not an external hard disk, which is typically larger and may use magnetic storage or a larger SSD. It’s not a Blu-ray Disc, which is an optical disc read by a laser.
