USB (Universal Serial Bus) ports have had a huge impact on the world of computers. They allow for plug and play of many devices, including external hard drives and USB flash drives for storage. They also allow for simple connection of printers and other peripherals, even lamps, fans, and novelty items such as tiny fridges that can hold and cool a single can of soda. Usually, USB ports are easy to troubleshoot.
