TECH 101: USB (Universal Serial Bus, USB 3.0, SuperSpeed USB)
USB (Universal Serial Bus) is a plug-and-play interface between a computer and add-on devices, such as media players, keyboards, telephones, digital cameras, scanners, flash drives, joysticks and printers. USB supports hot-swapping, which means that a new device can be added to your computer without having to add an adapter card or even having to turn the computer off. The USB peripheral bus standard was developed by Compaq, IBM, DEC, Intel, Microsoft, NEC, and Northern Telecom. The technology is available without charge for all computer and device vendors.
