How to Root Android:
 
What is rooting:
"Android 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") 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. On 
Android, rooting can also facilitate the complete removal and 
replacement of the device's operating system, usually with a more recent
 release of its current operating system.
