Android rooting basically means gaining unrestricted access to your phone's operating system. Through this process you can access Android's subsystem which allows you to run certain apps you couldn't normally run, modify settings within your system and basically do whatever you want and weren't able to do before. Most of the people use this in order to replace their current operating system with a custom one, to remove unnecessary apps that cannot be uninstalled (bloatware) all of which lead to a better optimized memory, CPU and battery usage . However all those restrictions were put there for a reason, so keep in mind that you do this with the risk of losing your warranty.

When you buy your phone, it becomes yours, but it's not like you get unrestricted access to commands.

In doing this, the Superuser app gets installed and sometimes in order to change your Android ROM you have to unlock your device's bootloader verification.However you do not need to perform this operation in order to run apps not found in the Google Play Store. Android has the "Unknown sources" option and the "Android debug Bridge" to permit this. In turn, modifying system files will be possible alongside performing activities and using apps which need this kind of access.
So how is it done?
The process varies from device to device, but there are some key steps found every time, like exploiting bugs in the device's firmware, copying the su binary to a location in the process' PATH variable while giving it higher permissions with chmod.
