Definition: Deck joists are boards (often 2x8s or 2x10s) that form a structural framework important to the stability of a deck. In addition, the tops of the deck joists form the surface to which the "floor" or decking material of the deck will be applied using nails or screws.
When building a deck that will be adjacent to a house, joists are often attached at the house end using a header board. The joists will be "hung" from the header board using joist hangers, keeping the tops of the joists at the same level as the header board. At the opposite end the joists commonly rest on top of a girder, which in turn is supported by posts.
