What is the practical difference between the peninsula and bridge components on a U-shaped desk?

The bridge and credenza are functionally different components at OfficeFurniture2go.com. A bridge is typically 18" deep — enough for a second monitor or reference materials — with minimal storage. A credenza is 20–22" deep with lateral file or storage drawers below. We typically recommend a credenza rather than a plain bridge for full U-desk configurations unless the rear position is against a window or the user wants a more open feel behind them.
