Explanation
Universal Serial Bus (USB) is a standard-based, external bus for a computer that brings the Plug and Play capability of hardware devices. You can use a single USB port to connect up to 127 peripheral devices, including speakers, CD-ROM drives, tape drives, keyboards, scanners, and cameras. USB supports hot plugging, which means that you can install or remove a USB device while the computer is running and the operating system automatically reconfigures itself accordingly. USB eliminates the need to install internal cards into dedicated computer slots and reconfigure the system.
