An Operating System (OS) is the core software that bridges the gap between computer hardware and the user. It manages all the fundamental operations, from running applications and allocating resources, to handling files and ensuring system security.
In simple terms, it serves as the “manager” of your computer, making sure every process and device works together efficiently.
The OS takes care of complex tasks behind the scenes, such as memory management, CPU scheduling, and device communication, so that users and developers can focus on their work without worrying about low-level hardware control.
In this section, we’ll explore how operating systems are structured, their main components, and why understanding them is crucial for developers who want to truly grasp how computers work from the inside out.
