A BIN file, short for binary file, is a type of file that contains machine-readable code that can be executed by a computer's processor. In the context of BIOS updates, BIN files are used to store the updated BIOS firmware. When a BIOS update is released, it is often packaged in a BIN file, which can be flashed onto the system's BIOS chip to update the firmware.
