Part 2. What is Android Firmware?

The ROM (Read Only Memory) operating system that we discussed is also known as Firmware. Through the device, they have access to the users without any type of modification and they stay firm. Thus, it is known as Firmware.

* It's possible to modify the firmware, but it is not under the easy usage.

* Read only through the software protection can remove or overwrite without any help of specialized hardware.
* It is done by only using the software written for the purpose and often it needs no connection to a computer.

So, Operating System and firmware both are the same thing and these can use any of them to such devices.
