What is USB?
USB (Universal Serial Bus) is a standard interface port on desktop and laptop computers. Nearly all recent computers provide USB ports, both Windows and Macintosh computers. USB supports the connection of up to 127 devices simultaneously, any of which may be plugged into or unplugged from the USB bus at any time - even with the power on! Whats more, it is the perfect solution for portable users, as all recent laptops also offer USB ports. Everything remains external to the computer and therefore no computer disassembly is required.
