Which device plugs into a USB port and acts as portable memory?

• A. Cloud Storage
• B. Removable Hard Disk Drive
• C. A Flash Memory Storage Device That Plugs Into a USB Port or a Computer or Mobile Device. Thumb Drive
• D. Blu-ray Discs

Answer: (C)

A USB flash drive is a small data storage device that uses flash memory and plugs directly into a USB port on a computer or mobile device. Because it uses flash memory, it has no moving parts, is durable, and retains data when power is off. It’s designed for portability, so you can carry files with you and plug it in to transfer data quickly across devices. Other options don’t fit as neatly: cloud storage is online rather than a physical device you insert into USB, an external hard drive is portable but uses spinning disks rather than flash memory, and Blu-ray discs require a disc drive and aren’t a USB memory device.
