Pen drive

A pen drive, also known as a USB flash drive, is a portable device used to store and transfer digital files. It connects to computers and other compatible devices via a small USB port. Inside, it contains flash memory—a type of storage that retains data even when unplugged. Pen drives are compact, lightweight, and easy to use, making them ideal for backing up documents, photos, videos, and other data, and transporting them between different devices quickly and conveniently.
