Firmware is a critical component of many electronic devices as it acts as an intermediary between the hardware and higher-level software applications. Unlike regular software that can be modified or updated easily, firmware is closely tied to the hardware it operates on. It is often stored in flash memory or ROM (Read-Only Memory), meaning updates can require specific procedures, unlike applications that can be downloaded and installed from app stores or software repositories. Firmware updates can enhance device performance, fix bugs, add new features, or improve security.
