USB stands for Universal Serial Bus and is a common component on new computers. The port looks like a flat slot and there are usually two of them together. Up to 127 devices can be chained together and attached to the computer. Many new computer peripherals (printers, digital cameras, scanners, speakers) come with USB adapters that allow the user to plug the unit into the computer and use it immediately without having to install expansion cards inside the computer and make manual adjustments to the computer settings.
