What is a device driver in operating systems?
In: 3
Devices are discrete parts of the computer, right? Like a network card or an optical drive or a video card, right? Drivers tell the operating system how to work it, how to send instructions to the device and how to interpret whatever information it gets back from the device and incorporate that with that the OS wants to do.
Firmware is code on the device itself that tells it how to do stuff regardless of what computer or OS it resides in.
So if you were driving a delivery truck the knowledge in your brain on how to drive the truck would be the firmware instructions and your boss telling you where to drive and drop off your load and what else to pick up would be the drivers.
