Drivers are computer programs that allow hardware devices to communicate with higher-level programs. The Device Manager lists all hardware drivers installed on a system, including display, network, sound, and USB drivers. To install a driver, it must first be uncompressed into a folder. The driver files or folder location must then be pointed to during the Windows installation process. Finally, the computer should be rebooted for the new driver to take effect. If a driver installation fails, the BIOS, jumpers, and cabling should be checked along with the manufacturer's website for troubleshooting tips.
