Flash Drive

A portable USB storage device that uses NAND flash memory.

Definition

Flash drives are used for file transfer, bootable OS installers, and recovery media. They can introduce malware or leak data, so organizations often restrict removable media. They are commonly formatted FAT32 or exFAT for cross-platform use.

Example

Use the Windows Media Creation Tool to make a bootable Windows 11 USB flash drive.

Exam tip

Bootable installer media and removable-media security policies both appear on exams.
