In short:
ADB = A tool to control and manage your Android device from your computer.

Why is ADB Important?

• For Developers: It helps in testing and debugging Android apps quickly.
• For Advanced Users: It allows you to install apps manually (APK files), take backups, and access hidden features.
• For Embedded Engineers: It is often used to test Android-based embedded devices.

So, whether you are a developer, a tech enthusiast, or just curious, ADB is a must-know tool.

How to Install ADB?

Installing ADB is very easy. Here are the steps:

1. Download ADB:
   • Go to the official Android developer website and download the “Platform Tools” package.
