Port replicators vs. docking stations

A port replicator is an attachment for a notebook computer that allows a number of devices such as a printer, large monitor, and keyboard to be simultaneously connected. Each of the devices is attached to the port replicator and when the notebook user wants access to one or more of the devices, the user simply attaches the port replicator rather than having to connect one device at a time. The port replicator duplicates each of the notebook's port , including parallel and serial ports. In addition, it may provide some extra ports for devices such as joysticks or Musical Instrument Digital Interface ( MIDI ) devices.

A port replicator is similar to a docking station , but does not include expansion slot .

Connecting a notebook to a port replicator is a simple process:

Attach all devices needed to the port replicator.

Close the notebook's display panel and align the connectors of the port replicator to the notebook ports.

Gently press the notebook down until the securing tabs lock into place.

Open the display panel and use the computer.

The notebook computer can be on or off during the connection and disconnection process. To disconnect the computer from the port replicator, press the notebook release buttons and lift the notebook away from the replicator.

12.24. Docking Station / Port Replicator

 There is a difference between docking station and port replicator.

I use the term docking station for a box which contains slots to put some interface cards in, and space to put a harddisk, etc. in. This box can be permanently connected to a PC. A port replicator is just a copy of the laptop ports which may be connected permanently to a PC.
