Device driver:-A device driver is a program that controls a particular type of device that is attached to the computer. Device driver or software driver is a computer program allowing higher-level computer programs to interact with a hardware device.
A driver typically communicates with the device through the computer bus or communications subsystem to which the hardware connects.There are device drivers for printers, displays, CD-ROM readers, diskette drives, and so on.
A device driver essentially converts the more general input/output instructions of the operating system to messages that the device type can understand.
For example, all printers come accompanied with drivers to install that tell the operating system exactly how to print information on the page.
