SimVars are “simulation variables” and they are the way that third party APIs and add-ons can get information about the current state of the simulation. In general these variables are used to control aircraft behaviors by permitting you to retrieve data about things like weather conditions, position, or aircraft status, and in many cases they can also be used to modify something within the simulation, in particular aircraft instruments and controls - although they can also have many other purposes within any add-on package.

Event IDs are used as a way to interface between different systems, with the user at the top level and the various sub-system within the simulation at the bottom. Generally they will be used as part of the Gauge/Panel API, and also when using RPN to generate Model Behavior inputs, although they may also have other uses.
