If you are an avid ‘Linux/Unix’ user then I don’t need to answer these, but for others let me put it this way. If you have read till now you would realize that Linux Kernel is in the heart of this device. So all the inherent features of operating system would be same as Linux. Therefore which is the one user which can do anything/everything on a Linux system?
The answer is Root aka super user, and hence the term rooting.
Rooting gives you the rights/permission to do certain tasks on android which has inherently been blocked by the handset makers for both simplicity and security of the device. You might have noticed that when you install any application from android market, it asks for certain permissions. Similarly there are some applications which require system level permissions for them rooting is required.
There are different ways to root android (depending on the version), but we will not deal with them here

Rooting is a process allowing users of smartphones, tablets, and other devices running the Android operating system to attain privileged control (known as "root access") within Android's subsystem. Rooting is often performed with the goal of overcoming limitations that carriers and hardware manufacturers put on some devices, resulting in the ability to alter or replace system applications and settings, run specialized apps that require administrator-level permissions, or perform other operations that are otherwise inaccessible to a normal Android user. Rooting is analogous tojailbreaking devices running the Apple iOS operating system or the Sony PlayStation 3. On Android, rooting can also facilitate the complete removal and replacement of the device's operating system.
