Port Replicator
The optional port replicator gives you a convenient way to 
attach external devices such as a monitor, a full-size 
keyboard, or an AC adapter.
Although devices can be attached directly to the ports on 
the notebook, the port replicator lets you make all of those 
connections in one step. The port replicator also gives you 
access to additional ports not found on the notebook.
