What is Firmware?

Firmware is a type of software that is embedded into hardware devices to control and manage their operations. Unlike regular software that can be easily updated or removed, firmware is typically stored in non-volatile memory, such as ROM or flash memory, and is essential for the device to function. It provides low-level control over the hardware and allows the device to communicate with other systems or applications.

Firmware can be found in a variety of devices, including routers, switches, computers, and embedded systems. It is responsible for initializing the hardware during startup and providing the necessary instructions for its operation. In many cases, firmware updates are released to fix bugs, add new features, or improve performance.
