What's the difference between a peninsula and a credenza on a U-shaped desk?

On a U-shaped desk, the peninsula (or bridge return) is the work surface that runs perpendicular to the main desk and connects to the other return, forming the bottom of the U. A credenza is typically a standalone storage unit with drawers and/or doors that can serve as the bridge surface in a U configuration. The credenza adds significant storage that a standard peninsula surface doesn't include. FindOfficeFurniture.com has U-shaped desk systems with both configurations — call 888-719-4960.
