Firmware is a type of software that is stored on a hardware device, such as a computer’s motherboard or a network router. It is responsible for initializing the hardware and providing basic functionality, such as controlling the input/output (I/O) devices and managing the memory. Firmware is typically written in a low-level programming language, such as assembly language or C, and is stored in a non-volatile memory chip, such as a flash ROM or EEPROM.
Firmware is essential for the proper functioning of a computer system. It provides the basic instructions that the hardware needs to operate, and it also manages the interaction between the hardware and the operating system. Firmware is typically updated by the manufacturer of the hardware device, and it is important to keep the firmware up to date to ensure that the device is functioning properly.
