About Firmwares
Firmware refers to the applications and operating system that control how a cellphone or smartphone operates. It is called firmware rather than software to highlight that it is very closely tied to the particular hardware components of a device. Firmware is generally flashed into a phone's ROM rather than simply being loaded into normal phone storage, where it could more easily be erased and lost in the event of a crash. Firmware updates are sometimes provided by a company as a way to fix bugs or introduce new functionality.
