A joist can be a board as small as a 2 x 6 on up to a 2 x 12. A "beam" can be as simple as two joists nailed together. Beams will change depending on the load required of it. Some beams will require three 2 x 12s, glued and screwed or extreme loads or spans will call for engineered wood beams or even steel "I" beams with pipe columns.
A roof joist is a horizontal beam that supports the ceiling, while a rafter is a sloped beam that supports the roof. Joists are typically found in the horizontal plane, while rafters are angled to support the roof's pitch.
A ceiling joist is a horizontal beam that supports the ceiling, while a rafter is a sloped beam that supports the roof. Ceiling joists are typically located horizontally, parallel to the ground, while rafters are angled to support the roof's pitch.

A roof joist is a horizontal beam that supports the ceiling below, while a roof rafter is a sloped beam that supports the roof itself. Joists help distribute the weight of the roof and ceiling, while rafters provide the framework for the roof's shape and support the weight of the roof materials.
The key difference between a rim joist and a band joist in a building's construction is their location and function. A rim joist is located at the edge of a floor system and provides support for the floor joists, while a band joist runs horizontally around the perimeter of a building and helps to distribute the load of the structure.
beam transfer loads from the joist to the wall or column where it supports..
