Android Debug Bridge (adb) is a command line tool that lets you communicate with an emulator instance or connected Android device. It is the command line interface (CLI) for Android. You don’t have to install Android Studio if you only want to use adb.exe. It is a good idea to install Android Studio however. Note that As of 2015, Android Studio, made by Google and powered by IntelliJ, is the official IDE; however, developers are free to use others. Previously, the official IDE for Android was Eclipse. Don’t use Eclipse.
The Android Debug Bridge (ADB) is a toolkit included in the Android SDK package. It consists of both client and server-side programs that communicate with one another. The ADB is typically accessed through the command-line interface, although numerous graphical user interfaces exist to control ADB.
