Why operating systems are essential in Intro to Computing - Flowchart Breakdown

Process Overview

An operating system (OS) is essential because it acts as a manager and helper for your computer. It controls hardware, runs programs, and makes sure everything works smoothly together, just like a conductor leading an orchestra.
