What type of device is a thumb drive?

A thumb drive, commonly known as a USB flash drive, is indeed a storage device that fits into the USB port of a computer. Its primary function is to store and transport data, making it a portable solution for users who need to transfer files between devices. They are compact, making them easy to carry, and they can hold a significant amount of data compared to traditional floppy disks or CDs.

The design of a thumb drive allows it to connect directly to a USB port, which is a standard interface on most computers and many electronic devices today. This direct connection is what enables easy access to its stored data without the need for additional cables or equipment. The convenience and portability of thumb drives have made them a popular choice for both personal use and in professional settings for data backup and transfer.
