When you click a program, what actually happens?
In this video, we break down how software is loaded into memory — step by step — without diving into code or low-level technical details. You’ll learn what the operating system really does, how working memory is assigned, and why a program on disk is not the same thing as a running process.
We clarify the difference between a program and a process, explain why execution requires permission, and show how the OS acts as the manager of the machine — not the executor.
If you’re learning programming fundamentals or trying to understand how computers truly work beneath the surface, this mental model will change how you think about execution.
Next: Why isolation makes reasoning about software possible.
