'''Over the back''' or '''over the top''' are terms used to describe an alternative connectivity [[data path|path]] between two more more boards plugged into a [[backplane]]; i.e. not using the [[bus]] carried by the backplane.

On the board edge opposite to the 'fingers' which plug into the backplane, a [[flat cable]], or in some cases a small [[printed circuit board]], with a pair of connectors plugs into [[Berg connector]]s each board.

In a few cases (e.g. [[PDP-8]] [[main memory]]), instead of connectors, the back edge of the boards ''also'' has contact fingers, and what is effectively a small plug-on backplane is used to connect the cards.
