What is Firmware, where to find it and how to know which one is mine?

BIOS (Basic Input / Output System) is the firmware interface between a PC’s hardware and its operating system. UEFI (Unified Extensible Firmware Interface) is a standard firmware interface for PCs. UEFI is a replacement for the old BIOS firmware interface.

The interface specifications firmware extensible (EFI) 1.10. It is designed to improve software interoperability and address BIOS limitations.

A firmware is a computer program that determines the logic of the lowest level that manages the electronic circuits of a device, no matter what class, it is constituted with the device electronics thus being the software that has the direct connection with the hardware.

Therefore, we can say that the firmware is the software that physically controls the hardware. For this reason, it is so important to update the firmware correctly, since even the smallest error can mean that the device is damaged and in the end that damage is irreversible.

Firmware is very important to our devices, since it must fulfill three important functions which are:

• First, gives the system in just a matter of seconds, the fundamental operating routines and the response to the usual requests that it receives and must satisfy the user.
• Secondly, Another of the tasks it performs is to establish a comfortable and simple interface so that in this way the configuration of the system can be started quickly and easily by using a certain series of parameters.
• In third place, we find ourselves with one of the most important functions that all firmware undertakes, we are talking about controlling and managing what is the boot of the device system, what would be the ignition.

Memory chips, printers, monitors, and microprocessors (phones, tablets and computers)These are some devices that have firmware, in case you do not realize a clear example of firmware is the BIOS program of a computer, it begins to work from the moment the machine is turned on.

A very important fact that firmware can be updated, as this helps to fix errors and increases performance. Although not many times this kind of updates are recommended because if a failure occurs this can cause the device to stop working completely, but if this problem does not happen, the update has its advantages, for example in certain devices it allows the increase speed.

You do not have to be an expert To be able to perform a firmware update, you just have to look for the firmware of your device and that’s it, there you can see if you really need the update or not. If you do not know how or where to look, we will tell you how to do it below.

To look it up on the computer in case you have to update your computer follow the steps below:

• Click the button Start and enter Control Panel
• Then go to System and look for Tools, then enter Device administrator.
• Search through the list until you find the specific device for which you want to check the Hardware.
• Click on the list and there it will show you the firmware information.

To look it up in your mobile device To find out if everything is up to date is much easier and you should follow these steps:

• On Sony and Samsung devices you should go to Settings, then About device and finally build number.
• In other devices you must enter Settings, then About device, then Software Information and last Software Version.

With these indications you can be informed about your firmware and if you need any kind of update. Something that without a doubt can make everyone’s life easier and that in turn would help us in our daily development of tasks, in this sense we are committed to downloading and updating the Android Firmware.
