Nowadays the term Drivers does not have the same amount of weight attached to it as it used to about 15 years ago. Back then finding Drivers that were released for a particular device was almost as difficult as getting a Republican to endorse President Obama. But Drivers remain important nevertheless.
A device Driver is the software that functions as a bridge between your hardware device and the Operating System. It tells the OS exactly how the hardware can be operated, what functions it is capable of and how the OS should “talk” to it. This is very important as OS manufacturers and hardware manufacturers are almost never the same entity.
These days with OS’s like MS Windows 7, there is really no worry about getting a device to work as the OS contains many thousands of drivers from manufacturers as well as generic ”one size fits all” drivers. But it is always advisable to get the newest driver for your device whenever possible. This is because manufacturers are constantly trying to get the best out of their hardware and therefore from time to time keep releasing new updates that will make the hardware improve its functions. Another reason is that OS’s regularly update themselves, thus requiring small or large adjustments in the way that drivers and hardware interact with them.
To keep your computer running as smoothly as possible, download updates regularly or if an automatic download option is available then you should utilize that. Many manufacturers now include an “identify make & model” tool on their websites, so even downloading the correct driver manually is now an easy task.
