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 sub-system.
Rooting is often performed with the goal of overcoming limitations that carriers
and hardware manufacturers put on some devices. Thus, rooting gives the
ability (or permission) 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.
As Android derives from the Linux kernel, rooting an Android device gives similar access administrative permissions as on Linux or any other Unix-like operating system such as FreeBSD or OS X.
Root access is sometimes compared to jailbreaking devices running the Apple iOS
operating system. However, these are different concepts. Jailbreaking
describes the bypass of several types of Apple prohibitions for the end
user: modifying the operating system (enforced by a "locked
bootloader"), installing non-officially approved apps via sideloading,
and granting the user elevated administration-level privileges. Only a
minority of Android devices lock their bootloaders—and many vendors such
as HTC, Sony, Asus and Google explicitly provide the ability to unlock devices, and even replace the operating system entirely.Similarly, the ability to sideload apps is typically permissible on
Android devices without root permissions. Thus, it is primarily the
third aspect of iOS jailbreaking relating to giving users superuser
administrative privileges
