[USB Flash Basic] What is a USB Flash Drive, and what is its primary function?

A USB Flash Drive is a data storage device that integrates NAND flash memory (the same technology found in SSDs) with a Universal Serial Bus (USB) interface.

Primary Function:

• Portable Data Storage: Its main purpose is to provide a compact and highly portable solution for storing, transferring, and backing up digital data (documents, photos, videos, music, applications, etc.).
• Plug-and-Play: USB flash drives are "plug-and-play" devices. When you insert one into a computer's USB port, the operating system typically recognizes it as a mass storage device and assigns it a drive letter, allowing you to use it like a small, removable hard drive.
• Convenience: Their small size, light weight, and bus-powered operation (no external power supply needed) make them incredibly convenient for carrying data between different computers or sharing files.
