Alright class, settle down now, let’s talk about “module,” how! The dictionary gives you a good start, it's true, But let’s break it down, just for me and you. Think of it like this: imagine building blocks, see? Each one is a module – independent and free! A “module” is a piece, a self-contained part, With its own job, right from the start. It has a defined interface , that’s key you see, Like a doorway or window - how it connects to be! It tells other parts, "Hey, I do this thing," And expects them back, with a helpful swing. Interchangeable? Absolutely right! You can swap one out for another, shining bright! So, a module’s a unit, neat and well-planned, Working together, hand in hand! Does that make sense to you all today? Any questions before we move on?
