What are "Drivers"?
Drivers are small programs that make your hardware work and play nice with the rest of your computer. For example, you hook up a printer to your PC but it won't work unless you put the CD in the drive and install its "drivers". As a convenience, sometimes very common drivers are included in the Windows operating system itself - saving you having to download or install them from CD. In fact, Windows itself uses many internal drivers you never see, but are instrumental in making Windows work.
Driver can also be understood in the context of a person driving a car - you have the car in the garage but it won't go anywhere unless someone gets in the seat, turns it on, pushes the gas pedal and knows how to obey the traffic rules. Put the wrong driver behind the wheel (like say, a 5 year old that doesn't know the rules or how to work the brake) and what happens? The car crashes or just doesn't go! Same with your printer, scanner, mouse, and anything else that's attached or inside your computer. Our driver also needs to be told about new driving rules or perhaps someone added a GPS to his car for which he needs instructions - same with your computer - that's why it's important to update drivers sometimes.
Updates are sometimes necessary because there is something new. The auto driver has to get information about the new rule so he can continue to operate the automobile safely and without problems. Same with your PC. When one area of your PC is upgraded (new video card, windows update) sometimes you need to get new drivers so other peripherals (printer, scanner, something internal) can understand the new rules. Updated drivers also fix minor problems that were found after the product was released - often called bugs.
The best part is most manufacturer's provide updated drivers free on their website's. It's not often nowadays that something is free - so take advantage of this and keep your PC running smoothly by checking to see if new drivers are available periodically for the peripherals (scanner, printer, other attached items) you use the most. |
