What are Driver Files?

Driver Files are pieces of code that help your computer interact with different hardware devices and peripherals attached (internally or externally) to your computer. Driver files are essential to the proper working of all the devices connected to your computer and without them, the devices can't work.

Every device and peripheral has its own driver files, which tell the PC exactly how to communicate with the device and make use of it. While modern operating systems (like Windows) come pre-installed with drivers files for common devices, there are still many devices that require you to install the driver files yourself.
