Firmware is software that is stored in non-volatile memory and provides instructions for controlling and operating hardware devices. Traditionally, firmware was commonly stored in ROM (Read-Only Memory), which is why programs that are as permanent as hardware are often referred to as firmware.
Firmware operates at a lower level than ordinary application software. It helps hardware components start up and perform their basic functions. For example, computers contain firmware that initializes hardware during startup and helps the system begin the boot process. Other devices such as routers, printers, cameras, keyboards, and smart appliances can also contain firmware.
Unlike regular application software, firmware is closely tied to the hardware it controls. It is stored in non-volatile memory, meaning its contents remain available even when the device is turned off. Although firmware was traditionally stored in ROM, modern devices may use flash memory or other reprogrammable non-volatile memory, allowing firmware to be updated.
