What is Firewall ? How It's Work.

Introduction

If you've ever used a computer and learned about firmware. When you update your computer and you've had a firmware update. you've wondered what it's all about.

In short firmware is a type of software that can only be uninstalled or uninstalled with a regular processor because it's not on the hard drive but is actually built into the hardware that performs very small tasks. It can also be called software for short.

What is firmware?

You've probably wondered many times what they had to do halfway through to connect the hardware to the software, because how would the hardware know that the software wants to do something with it?

The software also knows what hardware features it can use, so we use firmware to connect the two.

Firmware is a very small piece of software written into the built-in memory of a computer or any other piece of hardware and installed on that hardware when a company is built.

If you don't have Standby on your computer, you can't remove it because it's stored in your hardware's built-in memory, which can't be accessed easily.

Firmware is used in many electronic devices - D.V.D, remote control, washing machine, microwave oven, smart watch and other electronic devices because here you have to perform small tasks like setting the time or giving advice, less software at work. you can call Firmware Software.

The BIOS that comes with your computer is a kind of firmware because it is installed on the motherboard and without the BIOS you cannot install an operating system on the computer.

To install an operating system, you need a BIOS, so firmware plays an important role in connecting hardware and software.

Where is the firmware stored?

The Firmware Software (ROM) is locked, it is read-only, you cannot remove it or modify it, and if you want to remove it, you will have a lot of trouble with this because it is difficult to access the ROM.

You cannot install Firmware in ROM, during manufacturing the company gives you a setup, all the software that will be installed in the device, the manufacturer installs and if there is a problem they fix it. .

What is the difference between firmware and software?

Firmware differs from software because one is designed for the average user and the other is designed to add tools to the software.

If there is a difference, it comes from the software we use all the time like - Adobe Photoshop, Chrome, Internet Explorer, Firefox, VLC Player and others.

You can easily install the software, make changes and it does not change our hardware, because here it is saved on the hard disk. which we can easily delete modify.

firmware is somehow only intended for IT specialists, programmers who need to create firmware, who want to modify hardware, firmware is far from the user's access or is stored in the computer's ROM . hardware. These are installed by the company itself.

The firmware is stored in ROM so it cannot be accessed because if a normal user has access to it then any change to it could permanently damage the hardware and harm you. So it is stored in ROM to keep it safe.

Why should I update the firmware?

Nowadays, manufacturers have also started implementing the process of updating the firmware of their hardware devices to add functionality to their hardware devices and increase the efficiency of use more.

Earlier we could not update the firmware but today we can do it but it is very dangerous because the firmware is very important.

That's why companies keep offering tools based on their products so you can update your firmware properly, but if you're not IT savvy I'd say go for it. This work should only be performed by a professional.

Please keep this in mind when updating the firmware.

Whenever you update the firmware. make sure you update from the original site because if you update the wrong firmware, your device will be damaged.

The device should not be bricked during the software update as this may cause permanent damage to the device.

To update the software. use the original tool provided by the company.

Before updating the firmware, always check the model number and version to ensure that the correct firmware is installed.
