What Is Rooting ?

You are in right place to know about what is Root !

Rooting is the process of allowing users of smartphones, tablets and other devices running the Android mobile operating system to attain privileged control (known as "root access") over various Android's subsystems. As Android uses the Linux kernel, rooting an Android device gives similar access to administrative permissions as on Linux or any other Unix-like operating system such as FreeBSD or OS X.

• Root: Rooting means you have root access to your device—that is, it can run the sudo command, and has enhanced privileges allowing it to run apps like Wireless Tether or SetCPU. You can root either by installing the Superuser application or by flashing a custom ROM that includes root access.

• ROM: A ROM is a modified version of Android. It may contain extra features, a different look, speed enhancements, or even a version of Android that hasn't been released for your phone yet. 

• Stock: "Stock" means the version of Android that came with your phone—e.g., if you want to get rid of your ROM and return your phone to factory settings, you might say you're "going back to stock."

• Flash: Flashing essentially means installing something on your device, whether it be a ROM, a kernel, or a recovery that comes in the form of a ZIP file. Sometimes the rooting process requires flashing a ZIP file, sometimes it doesn't.

• Kernel: A kernel is the component of your operating system that manages communications between your software and hardware. There are a lot of custom kernels out there for most phones, many of which can speed up your phone and increase your battery life, among other things. Be careful with kernels, though, as a bad one can cause serious problems with your phone and possibly even brick it.

• Brick: To brick your phone is to break it during flashing or other acts. There is always a small risk with flashing, and if your phone becomes unable to function—that is, it basically becomes a brick—you've bricked your phone. The risk is very small, however, and more often than not people say "brick" when they really mean "it turns on but doesn't boot properly," which is a very fixable problem.

• Recovery: Your recovery is the software on your phone that lets you make backups, flash ROMs, and perform other system-level tasks. The default recovery on your phone can't do much, but you can flash a custom recovery—like ClockworkMod or TWRP—after you've unlocked your bootloader that will give you much more control over your device. This is often an integral part of the rooting process.

• ADB: ADB stands for Android Debug Bridge, and it's a command line tool for your computer that can communicate with an Android device you've connected to it. It's part of the Android Software Developers Kit (SDK). Many of the root tools uses ADB.

• Nandroid: From most third-party recovery modules, you can make backups of your phone called nandroid backups. It's essentially a system image of your phone: Everything exactly how it is right now. That way, if you flash something that breaks your phone, you can just flash back to your most recent nandroid backup to return everything to normal.
