In this second lecture of the *GitHub Actions: Basics to Production* series, we move deeper into the GitHub Actions execution model by understanding how workflows are triggered and where they execute.

We will explore different GitHub Actions workflow trigger categories including repository events, manual triggers, scheduled workflows, external triggers, and reusable workflow orchestration. We will also understand GitHub Actions contexts, runner environment variables, GitHub-hosted runners, runner sizing considerations, and Ubuntu vs Windows runner execution behavior.

This lecture is designed to build strong operational understanding around workflow execution before moving into advanced CI/CD automation topics later in the series.
