Understanding the Way Device Driver Works

Adding a new hardware component to your computer requires that you have the right device driver installed on your PC. Every hardware component on your PC has its own unique device driver. For without it, the hardware will malfunction. For instance, the printer can print files and documents only if it has the right printer driver installed on the system. Failing to install the right device driver will cause the external hardware to act up.

Device drivers are files that contain unique code used by the operating system to identify and connect with various hardware devices. What makes up a computer is the external hardware including cams, mouse, keyboards, and printers, among others. The device drivers ensure these external hardware components work optimally.

Once installed the first time, it is highly unlikely that you may have to directly operate or interact with them unless of course, a particular hardware device develops an issue.

How to Fix a Dysfunctional Driver?

There comes a time when a driver starts to malfunction. In this case, the driver is likely outdated, hence it is due for an upgrade. This means you may have to upgrade the driver to the latest version. Over time, manufacturers make improvements to drivers just as a software developer does. So keeping those drivers up to date is essential.

An updated driver will function optimally and fix a variety of computer errors. For instance, if your scanner fails to scan properly, updating the driver can fix the errors. Upgrading a device software can be done over the internet by visiting the manufacturer’s website.

Keep in mind that a device driver that requires an update will be downloaded on your system just like every other software program on your computer. Most of these downloadable device drivers come in .exe version. Once the download is complete, updating will have to be done manually. Click on the downloaded executable file and follow the onscreen instruction to begin with the installation process. This process only runs for a short time and the installation will be complete. After successfully installing the driver, you are required to restart the system so that the newly updated driver can communicate effectively with the hardware device.
