Good place to grasp basic jargon/lingo as well as absolute basics, like what an i.d.e. is & how to use it & explains addons/plug

newbie looking for prep to learn the basic stuff before starting to learn to code. Setting up an i.d.e. or editor, what the lingo means, where to get help for different things, reference sites/apps for programmers/coders, and things like that.
