It is purely physical.SOFTWARE is the arrangement of digital instructions that guide the operation of computer hardware. Software is loaded from storage (flash, disk, network, etc) into the computer's operating memory (RAM) on demand, and is designed to be easy to change.FIRMWARE is a special class of software that is not intended to change once shipped.
