Device drivers are computer software parts that allow application programs to communicate with hardware components. For example, sound card drivers allow multi-media applications to deliver sound to the computer speakers. When a user instructs a program to adjust the sound, the driver is the software associated with the sound card. It is responsible for giving the instructions to the hardware so it can change the volume sent to the speaker. Drivers exist for all hardware components. Windows operating systems come with many generic drivers pre-installed. Writer Bio
