What is Bootloader? Bootloader of Android.



What is Bootloader?
In literal terms, bootloader is code that is executed before any Operating System starts to run. The concept of bootloaders is universal to virtually all Operating systems that inculcates operating systems on your PC, laptop, smartphones, and other such devices. Bootloaders basically package the instructions to boot operating system kernel and most of them also have their own debugging or modification environment.

Android Bootloader?
Think of the bootloader as a security checkpoint and manager for all those partitions. Every computer has one, and it's what tells the hardware where to look and how to get running when you start things up.On Android phones (and tablets, and TV boxes, and even microwave ovens) the bootloader checks a few things by default to make sure the software you're trying to start up is genuine. Most mobile or embedded devices are the same way, and that's because if you're able to swap out what the people who made your phone put on those partitions, you're able to break things if you don't know what you're doing, or bad software might try to mess with all your stuff. The flip side is an unlocked bootloader that doesn't verify the software makes it easy to install and use custom ROMs. This is why people want to be able to unlock them.

Why manufacturers lock the Bootloader?
Manufacturers lock the bootloader of their devices so that only the operating system installed on the device can be used. Not all brand acts in the same way either: some manufacturers release their smartphones with the bootloader already unlocked (to the delight of most computer geeks).
