What is the root Take a look at the advantages and disadvantages of the route.

What is the root
In the simplest terms, the root is the administrator or administrator. Although its Bangla meaning is root of the tree, the root in Linux world refers to permissions or permissions that make the user all-powerful (of course only on that computer, device or server!). Root is a permissions or permission. If this permission allows the user to do so on the device. In the Windows operating system, the user administrator can not work with system files without Privilege (which is usually in C Drive). Linux administrators can not do the same without getting the root permissions user. You can do whatever you like on a Linux-powered computer or server, or whatever you have permission to do is called root user. Many times it is also referred to as a superuser.
The word has become so popular that instead of saying the root user is addressed to the user directly as the root. That means, if you are a root user with access to your Linux operating system, then you are root.
Routing facility:
Increase performance: Keep the phone's speed untouched by using different applications, regularly unpacking files, temporarily files etc.
Overclocking: The speed of the CPU is as fast as possible, as fast as possible. This can be done if there is a need to speed up processor speed in a particular task.
Underclocking: When the device is left, the CPU does not work unnecessarily for reducing its ability to work. It is possible to increase the battery backup.
Custom UI: The design of your device's home screen, lock screen, menu etc., may be better after a time of different user interfaces. Then you can bring innovation on the device through all new custom user interfaces. These are also called roms in another way.
Custom ROM: The ability to install Many developers have created custom ROMs for various popular devices. By installing these ROMs you can set your set to a whole new set. Of course, its wings will not grow from the outside or the camera will not be 8 megapixels from 5 megapixels, but the changes in interior design and field performance will be a major change.
The difficulty of the route
Losing warranty: By warring your device, your warranty will be canceled. So be careful before routing. Of course, many sets can be re-unirooted. And if the set is unrotected then the technicians at the service center can not hold that the set was rooted. But there is no way to avoid catching a custom ROM.
Brick phone: Brick means brick. And the phone brick means to turn your device into a brick. That is, losing its ability to do it. There may be permanent or temporary problems on the phone if it is a little bit of time during routing and subsequent work. The manufacturer of your phone will give the phone an unutilized condition so that it does not hurt. By routing you are breaking that guarantee.
