A firmware is the combination of persistent memory and program code and data stored in it. Editing a firmware file in a hexadecimal, or hex, editor can allow you to modify a device's behavior. For example, you can change the speed of manufacturing equipment or enable hidden features on a router or cell phone by editing their firmware files. Editing the values of a file by using a hexadecimal editor can be daunting due to the fact that such a program displays cryptic raw machine code.
