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 perform an automatic function. Although it is true that the Firmware is created from a source code that is written through software, it has a more physical relationship than any program can exert on a computer.

These programming languages ​​are stored in the ROM memories, that is, the internal data stores of the equipment, a RAM is in charge of keeping the order active while executing the process and the processor of sending it to the indicated part of the system so that is made.

The Firmware adds from the most fundamental commands to the machine to the most complex ones. The hardware manages with its different capacities all the orders that the system of automatic laws 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, stereos and even vehicles.

The Firmwares of electronic equipment are updated not to add new options and alternatives as computer software does, they do so to repair or improve the connection of hardware functionalities with those indicated in the law or created standard. We cannot fail to mention that many electronic devices 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 played efficiently.
