What Is Operating System?
======================
An Operating System (OS) is software that acts as an intermediary between computer hardware and the user. It manages hardware resources, provides services to applications, and facilitates user interaction with the computer. Key functions of an OS include:

1. Resource Management: Manages CPU, memory, storage, and other hardware resources.

2. File System Management: Organizes, stores, retrieves, and manages data on storage devices.

3. Process Management: Handles the execution of processes, including multitasking and process scheduling.

4. User Interface: Provides a user interface, like a command line or graphical user interface (GUI), for interaction with the system.

5. Security and Access Control: Protects system data and resources from unauthorized access.

Examples of operating systems include Windows, macOS, Linux, and Android.
