The function of firmware in electronic devices is to provide low-level control and functionality specific to that hardware. Firmware is embedded software that runs on the device itself and is essential for managing its operations, settings, and interactions with other components. Unlike regular software, firmware is typically stored in non-volatile memory, enabling it to function even without power. Updates to firmware can enhance performance, fix bugs, and improve security. Examples of devices that rely on firmware include printers, routers, cameras, and embedded systems in consumer electronics.
