Firmware: today electronic equipments like DVD Players, DTH set top box. Game consoles, and of course broadband modems. are using some sort of programs to do their work, like u use
windows/linux to work on your computer.
These piece of codes, programs are installed in hardware level, at the time of manufacturing. these software are called firmware.\
- Firmware is programming that is inserted into programmable read-only memory (programmable
ROM), thus becoming a permanent part of a computing device. Firmware is created and tested like software (using microcode simulation). When ready, it can be distributed like other software and, using a special user interface, installed in the programmable read-only memory by the user. Firmware is sometimes distributed for printers, modems, and other computer devices.
if after some time the company release new software/bugfix for their product, the firmware then should be upgraded. thats why u have firmware upgrade option. now if u go with wrong version of firmware (build for another model), your product may not work properly. so there is a option to backup your previous firmware, which is working perfectly.
