👉 Firmware computing refers to the software that controls and manages the hardware components of a device at a very low level, typically embedded in the device's microcontroller or processor. This specialized software operates directly on the hardware, enabling it to perform its core functions without the need for a higher-level operating system. Firmware is responsible for tasks such as initializing hardware during startup, managing input and output operations, handling interrupts, and controlling peripheral devices. It ensures that the hardware operates efficiently and reliably, often in real-time scenarios where quick response times are critical. Unlike traditional software, firmware updates are usually performed during manufacturing or through specialized tools, making it a crucial layer for maintaining the functionality and security of embedded systems.
