Quick answer
An online course is a structured set of lessons, usually grouped into modules, designed to build a skill step by step, often with progress tracking so the learner can pick up where they left off.
What separates a course from a guide is sequence: a course assumes you move through it in order, with each lesson building on the last, rather than being read as a single, standalone piece.
