What is a USB Flash Drive?

A USB flash drive, also called a pen drive, is a small storage device that connects to a computer through a USB port.

How It Works

The drive uses flash memory, which keeps data even when unplugged. Most computers recognise it instantly, a feature called plug and play.

Common Uses

• Transferring files between computers
• Backing up important documents
• Carrying presentations or assignments
• Storing photos and videos

Staying Safe

Always scan a USB drive with antivirus before opening files, and safely eject it before removing it to avoid data loss.

Why It Matters

USB drives are simple, cheap and useful. They are often the easiest way to move files when there is no Internet connection.
