Firmware is a type of software that provides low-level control, instructions, and operational code embedded in electronic devices, hardware components, or computer systems to enable their basic functionality, booting process, and communication with other hardware or software components. Firmware is stored in non-volatile memory (e.g. ROM, flash memory) and is typically installed or programmed onto devices during manufacturing or assembly. Firmware updates may be released periodically by manufacturers to fix bugs, enhance performance, add features, or address security vulnerabilities in embedded systems or IoT devices.
