Firmware usually refers to software for some kind of electronic equipment. Modern technologies allow you to independently replace the firmware version of many devices used in everyday life.
The term "Firmware" itself appeared relatively long ago - in the 60s of the last century. It was first used to create magnetic core memory. At that time, microcircuits were literally stitched with special wires in the right places. This process was originally done manually. A dozen years later, special machines have appeared that make it possible to automate this process. At the moment, updating the firmware or firmware is carried out by two main methods: replacing the microcircuit or changing the software. It is quite easy to replace software in certain mobile phones. As a rule, the companies that produce this equipment are engaged in the creation of software. It is important to understand that firmware is present in all devices that include microprocessors. These can be cameras, televisions, routers and various measuring devices. If you decide to change the software version of a particular device yourself, be sure to first make sure they are compatible. If we are talking about network equipment, then it is better to download software only from the official websites of the manufacturers of the devices used. Development of firmware, as a rule, takes more time than development of the equipment itself. Most licensing agreements do not allow you to extract firmware and make any changes to it. Some companies allow using their own freely available software in conjunction with certain devices. The most striking example of such firmware is the BIOS menu, which is present in all IBM-compatible computers of our time. The BIOS version can be changed using programs provided by some motherboard manufacturers.
