The firmware is the code used to manage the internal components. With a PC you could upgrade the BIOS (Basic Input Output System) which is the firmware without modify the OS. The firmware handle the power system per example. The firmware can be modified without modify the way that it respond to the software, the OS, via the Application Programming Interface or API. In a e-reader, a part of the firmware handle the e-ink screen.
The applications run in the OS. It is necessary to distinguish the both. It's possible to improve the application's performances with an upgrade of the firmware - in some case.
