Universal Serial Bus (USB) ports are rectangular slots normally found near other plug ports on your computer. USB was introduced as a fast way to transfer data among devices, while high speed USB, also known as USB 2.0, was released in 2000. USB 2.0 ports are backward compatible, since they are pre-installed with drivers for USB 1.0 and 1.1. However, your transfer speed will be limited by the speed of the USB port, so checking that you have high-speed USB ports is a good way to ensure fast data transfer.
Locate your USB ports by looking for the rectangular slots on the side of your laptop or the back of your desktop. You can recognize the USB symbol, which looks like a sideways "Y" or trident shape.
