Why Device Drivers Are Important To Your Computer
Overviews how a device driver (computer peripheral) or software driver (computer programs) allow higher-level computer programs to interact. Covers what the driver is, its purpose and how to keep a computer optimized with the correct driver(s).
What is a Computer Device Driver? According to Wikipedia, the free encyclopedia, “A device driver or software driver is a computer program allowing higher-level computer programs to interact with a device. A driver typically communicates with the device through the computer bus or communications subsystem to which the hardware is connected. When a calling program invokes a routine in the driver; the driver issues commands to the device. Once the device sends data back to the driver, the driver may invoke routines in the original calling program. Drivers are hardware-dependent and operating-system-specific. They usually provide the interrupt handling required for any necessary asynchronous time-dependent hardware interface.”
