Firmware is a specialized type of software that provides low-level control for a device's specific hardware. It is typically stored in the device's non-volatile memory, such as ROM or flash memory, and is essential for the device to function properly. Examples of devices that use firmware include routers, printers, and smartphones.
Unlike regular software that can be easily updated or modified, firmware updates are often more complex and may require specific procedures to install. These updates can enhance functionality, fix bugs, or improve security, ensuring that the device operates efficiently and safely.
