An Operating System (OS) is the main software that manages all the hardware and other software on a computer. It’s like the boss of your device—it tells the computer how to work and lets you interact with it easily.
🔧 Key Functions of an Operating System:
- User Interface
- Lets you interact with the computer (like clicking icons, opening apps).
- Example: Windows desktop or macOS interface.
- Resource Management
- Controls CPU, memory, storage, and input/output devices.
- File Management
- Organizes files on storage devices (saving, opening, deleting).
- Process Management
- Runs multiple programs and keeps them from interfering with each other.
- Security & Access Control
- Protects your data with passwords, permissions, and encryption.
💻 Examples of Operating Systems:
- Windows
- macOS
- Linux
- Android (for mobile)
- iOS (for iPhones and iPads)
🧠 Simple Analogy:
Think of the OS as the manager of a hotel—it handles everything so guests (apps and users) can have a smooth experience.
