Firmware is a system that is developed to establish a "Firm" link between Hardware and Software, hence its name, which was used for the first time in the 60s to indicate a set of standards inserted in an electronic card so that a larger appliance will run an automatic function. While it is true that Firmware is created from source code that is written through software, this has a more physical relationship than any program can exert on a computer.
These programming languages are stored in ROM memories, that is, the internal data storage of the equipment, a RAM is in charge of keeping the order active while executing the process and the processor sending it to the part of the system indicated so that is made.
Firmware adds from the most fundamental orders to the machine to the most complex ones. The hardware manages with its different capacities all the orders that the automatic law system issues. With the advancement in Microprocessor technology, these firmwares were elaborated in a more elaborate way and added to more everyday equipment: washing machines, kitchens, televisions, sound equipment and even vehicles.
Firmware of electronic equipment is updated not to add new options and alternatives as computer software does, it is done to repair or improve the connection of hardware functionalities with those indicated in the law or regulation created. We cannot fail to mention that many electronic equipment improve security protocols within the Firmware, for example: the firmware of a DVD or Blu Ray player updates its security protocols to prevent pirated discs from being reproduced efficiently.
