Printer Drivers
A driver typically 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. 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.
Driver is piece of software that knows how to communicate with specific hardware. For example when you plug your printer for the first time Windows operating system (and other too) does now know how to use this device. After installing the driver operating system will know that hardware that you plugged in is printer and how to control it. Just for better understanding: Operating System (Kernel) <----> Device Driver <----> Real Hardware
Type device manager into the start menu and open device manager, locate your web cam in the list of hardware installed on your computer and right click on it. Then click update driver.
Switches
The formatting of a diskette is done by the driver hardware. Any software that can access the driver hardware interface can do this.

Device driver.
It is called a device driver.
Ethernet is not a device, it is software protocol. There is hardware to implement the protocol, e.g. NICs, switches, hubs, etc.
a driver software is a type of system software which is required to interact the external device with the computer
type 'add hardware' into the search box to add drivers. you can choose from hundreds or use a disk that come with your device the icon is like a hard drive with a plus sign beside
