Built-in functions are functions that are provided for you by the standard includes. User-defined functions are those that you write yourself. Third-party functions are those that are written for you, but that are not provided by the standard includes.
In normal (ie imperative) programming, you define a set of operations to be performed sequentially, from start to finish in one go. In event driven programming, you define a series of "callback" functions, which are then called by whatever runtime system you may be using, in response to the actions of the user, or some other agent. Each function is associated with an action (eg the user pressing a button or clicking an icon), and is called by the system whenever the user performs that action.
