Device Drivers

What are Device drivers? How are device drivers updated?
 Answer:-

Device drivers  are specialized programs that allow device such as mouse, printer, scanner or keyboard to communicate with the rest of the computer system.

Every device, such as a mouse or printer , that is connected to a computer system, has a special program associated with it. This program , called a device driver or simply a driver, works with the operating system to allow communication between the device and the rest of the computer system.
Each time the computer system is started, the operating system loads all the device drivers into memory.

Whenever a new device is added to a computer system, a new device driver must be installed before the device can be used .
Windows supplies hundreds of different device drivers with its system software. If a particular device driver is not included , the product's manufacturer will supply one.
Many time these drivers are available directly form manufacturer's website.

You probably never think abut the drivers in your computer.
However when your computer behaves unpredictably , you find updating your drivers solves your problems.
Windows makes it easy to update the drivers on your computer using Windows Update.
