Imagine your computer is like a big office building. The operating system (OS) is like the building manager. It’s responsible for keeping everything running smoothly and efficiently. Here’s what the OS does:

1. Manages resources: The OS is like the building manager who assigns desks, meeting rooms, and other resources to different employees (programs) working in the office (computer). It makes sure each program gets what it needs to function properly, without conflicts.

2. Communicates with hardware: The OS acts as the translator between the programs and the physical parts of the computer like the keyboard, mouse, and printer. It tells the hardware what the programs need and translates the hardware’s responses back to the programs in a way they understand.

3. Provides a user interface: The OS is like the building’s reception area and hallways. It provides a user interface (UI) like the desktop, menus, and windows that allow you to interact with the computer and give instructions to the programs.

4. Handles security: The OS is like the building’s security guard. It controls access to the computer’s resources and protects it from unauthorized use or harmful software.

5. Manages files and storage: The OS is like the office filing system. It keeps track of all your files and folders, storing them on the hard drive and making them accessible to the programs that need them.

In simpler terms, the operating system is the essential software that makes your computer work. It’s the foundation for everything you do on your computer, from using programs to browsing the internet.

Here are some common examples of operating systems:

• Windows: Most commonly used on personal computers.
• macOS: Used on Apple computers.
• Android: Used on smartphones and tablets.
• iOS: Used on iPhones and iPads.
• Linux: Used on various devices, from personal computers to servers.

The steps may vary slightly depending on the Linux distribution you’re using. However, you can typically find the OS information by:

1. Opening a terminal window.
2. Typing the following command and pressing Enter:
