How are basement stairs supported?

Basement stairs are supported by what we call stringers, these are the side of the stairs where treads and risers are secured. Most staircases have two stringers, one that is on the wall and one that is on the outer part. Some stringers are not mounted on a wall because they are not stairwells.

But this will all depend on the different designs of stairs. Not all stairs are the same, some are more complicated than others. With different ways of building stairs being implored today, some support systems such as stringers might appear differently on other designs.
