Explanation

A USB flash drive is a device that can be used for input, storage, and output in a computer system. It is a versatile portable storage device that connects to computers through a USB port.

As an input device, a USB flash drive transfers data from itself into the computer. As a storage device, it holds data in its internal memory chips. As an output device, data can be copied from the computer to the flash drive.

The CPU is the brain of the computer that processes data, but it is not used for storage or direct input/output with external media. A monitor is an output-only device that displays information. A keyboard is an input-only device for entering data.

Other devices that serve multiple functions include external hard drives and memory cards. The USB flash drive’s portability and plug-and-play nature make it especially useful for transferring files between computers.
