Device Driver

Definitions

1. A specialized program that acts as a translator between the operating system and a hardware device, abstracting the device's specific protocol behind a standard interface.

   In plain English: Software that teaches your operating system how to talk to a specific piece of hardware. Without the right driver, your OS doesn't know how to use the device, like having an appliance with instructions in a language you don't speak.

   Example: "The webcam worked on Windows but not Linux because the manufacturer never released a driver. So someone reverse-engineered the USB protocol and wrote one."
