What is firmware?

Firmware refers to a type of software that is embedded in electronic devices or hardware components. It is responsible for controlling the operation and functionality of the device or component. Unlike regular software, firmware is typically stored in non-volatile memory, such as ROM (Read-Only Memory), and is not easily modified or updated by the user. Firmware provides the necessary instructions for the device to perform specific tasks and interact with other hardware or software systems. It is commonly found in devices like smartphones, tablets, routers, printers, and various other electronic devices.
