What Is Firmware?

Posted on July 2, 2021 Sara Lewis What Is Firmware?
Within the realm of computing, firmware refers to a type of computer software that enables a user to have a certain amount of control over a device’s hardware. In general, such firmware will have been developed by software engineers, ensuring that specific hardware functions as intended by a manufacturer. Firmware can be used for countless electronic systems and devices, ranging from simple traffic lights to the firmware stored on computer hardware. In this blog, we will discuss firmware more in detail, allowing you to understand its importance for electronic hardware.
As a set of instructions that are programmed onto hardware, firmware is necessary for a system to have the coding needed to function as intended and communicate with other hardware. To install firmware onto a particular device, such data will typically be stored in the form of ROM. ROM, or read-only memory, is a type of non-volatile memory that is common to electronic devices, and such data is incapable of being modified after the initial writing. With flash ROM, on the other hand, data may be written and rewritten as needed as the memory is a type of flash memory.
As firmware is developed and released by a manufacturer, such software programming may be considered semi-permanent due to its static state until any update is made. For various devices such as mobile phones, video cards, and cameras, updates to the firmware may be needed from time to time to ensure their proper functionality and compatibility with new devices. Additionally, firmware updates may even improve the functionality of some devices as software engineers make various advancements to the programming.
Depending upon the device in question, firmware updates may be obtainable from the device itself, requiring the user to find the setting required to initiate the update. In other devices, firmware updates may be procured from the website of the manufacturer, often being located in a “Support” or “Download” page. When updating a device from a computer, it will often have to be connected to the computer through a USB connection or other port for transferring data. While updating firmware for devices is not always necessary, it can be highly beneficial if there are changes made for the means of increasing performance or compatibility.
Firmware can often be found on a number of devices, commonly being used by a diverse set of consumer products. Electronic devices and mobile phones often have similar firmware, designed for updating programming that may have an effect on the device’s GUI, battery life, capability of playing certain file formats, and more. Mobile phones in particular also have what is known as Firmware Over The Air capability, meaning that updates can be distributed over Wi-Fi or mobile broadband networks. Automobiles also use firmware as well, often being used for sensors that detect mechanical issues, anti-lock braking systems, and computer-operated transmission control units. Beyond such examples, a number of other electronic hardware devices take advantage of firmware for their basic functionalities.
