Detailed explanation-1: -Device drivers are necessary to permit a computer to interface and interact with specific devices. They define the messages and mechanisms whereby the computer–the OS and applications–can access the device or make requests for the device to fulfill.
Detailed explanation-2: -A driver communicates with the device through the computer bus or communications subsystem to which the hardware connects. When a calling program invokes a routine in the driver, the driver issues commands to the device (drives it).
Detailed explanation-3: -Communication with Peripherals-Drivers. A driver in the Control Web serves for communication with a peripheral. For each device it is necessary to use the corresponding driver. The driver is inserted into the application, it is configured, and then it is possible to insert channels into the application.
