Channel Driver (i.e. Drivers / Expressions) (driver)
Channel Drivers are part of the dependency system, and are executed in addition to normal user-defined animation. They take the animation result of some channel(s), and use that (optionally combined with its own F-Curve for modification of results) to define the value of some setting semi-procedurally.
Drivers are stored as part of F-Curve data, so that the F-Curve's RNA-path settings (for storing what setting the driver will affect). The order in which they are stored defines the order that they're evaluated in. This order is set by the Depsgraph's sorting stuff.
