PARALLEL+PORT

=PARALLEL PORT=

A parallel port is a place to connect peripheral devices such as printers, external hard drives, or scanners to a CPU. It was originally developed by IBM for printers manufactured by Centronics (a major printer manufacturer at the time - Epson has recently begun to produce the more contemporary parallel devices ). Through the parallel port, the computer transmits 1 byte (8 bits) of information at a time to the peripheral device. However, instead of sending the 8 bits to the printer or scanner in a straight line (as in a serial port), they are sent parallel to each other.
