The USB peripheral bus standard was developed by Compaq, IBM, DEC, Intel, Microsoft, NEC, and Northern Telecom.
DB-25: A DB-25 connector is usually used for the 2nd serial port (COM2), often connected to a modem, as well as the parallel port (see printer cable). Furthermore,DB-25s are used in a wide variety of communications devices.
