USB memory sticks, also known as USB flash drives or thumb drives, are portable data storage devices that use flash memory to store and retrieve data. They typically connect to a computer or other device through a USB port and can be used to transfer files or to store data for backup or transportation.

USB memory sticks come in two main types USB-A and USB-C with different storage capacities, from a few gigabytes to several terabytes. They are small and lightweight, making them easy to carry around in a pocket or bag, and they are compatible with a wide range of devices, including computers, laptops, tablets, and some smartphones.

USB memory sticks are often used to back up important files, transfer data between devices, or store files for use on the go. They are also popular for distributing software or other files, such as presentations or photos, to a group of people. Many businesses and organisations use USB memory sticks as a promotional item or a gift to clients or employees, often pre-loaded with branded content or promotional material.
