A device used to quickly connect multiple peripherals to a laptop. The monitor, printer, network, keyboard and mouse are permanently plugged into the port replicator, which connects to the laptop via the USB port. A port replicator provides some or all of the functionality of a docking station, and the two terms are used interchangeably. However, a docking station uses a proprietary connector to the computer, whereas a port replicator generally provides a universal solution for all laptops via USB. See docking station.
