What is USB ? 

Limited expandability, difficult configuration and too many kinds of cables and connectors have made upgrading or adding new devices to a PC troublesome. The Universal Serial Bus (USB) has been designed to solve these problems and offer a standard solution for all external devices. Setting up PC hardware is no longer inconvenient.
Universal Serial Bus connectivity standard allows up to 127 devices that can be connected to the Host PC without using multiple connector types, interrupt conflicts (IRQs), DMA channels and hardware address adjustments (jumpers) .
