Android ek Linux-based Operating System hai jo mobile devices ke hardware ko manage karta hai, applications ko run karta hai aur user aur hardware ke beech bridge ka kaam karta hai.

Interview Definition

Android is an open-source, Linux-based mobile operating system developed by Google. It provides a platform for running applications, managing hardware resources, and enabling communication between applications and device hardware.

Just like:

• Windows runs on laptops and desktops.
• macOS runs on MacBooks.
• iOS runs on iPhones.
• Android runs on most Smartphones, Car dashboard and tablets, .

An Operating System is software that controls the entire device. It acts as a bridge between the user, the applications, and the hardware.

Real-Life Example

Imagine you have a smartphone.

Inside the phone, there are many hardware components:

• Camera
• Speaker
• Microphone
• Processor (CPU)
• RAM
• Storage
• Battery

These hardware components cannot work on their own.

When you open the Camera App, the app does not directly communicate with the camera hardware.

Instead, the process is:

User
↓
Camera App
↓
Android Operating System
↓
Camera Hardware

The Camera App sends a request to Android:

“Please open the camera.”

Android checks:

Is the camera available?
Does the app have camera permission?

If everything is okay, Android tells the camera hardware to start.
