Drivers are the mains for your computer to understand what a specific hardware component or device is capable of doing and what kind of system resources hat component will require in order for it to function normally.
For example, AMD drivers are used to tell your mother board what kind of processor is installed and what it is capable of running. HP drivers are usually meant to help you use either a digital camera, printer or an all in one office suite.
Asus drivers, the ones that are probably delivered with your mother board will provide with complete functionality from all the features that your mother board comes with. Toshiba drivers, on the other hand, are designed for the entire laptop (because that is the only way you will get this sort of drivers) and you need to install them if you want full functionality from your laptop.
Nvidia drivers are designed to be used with graphics cards, while Canon drivers are similar to HP ones and mainly used for printers and other office friendly hardware.
Logitech drivers can be found useful for webcams, gaming devices and even high-end sound systems. All these drivers come to you for free either on a CD that is supplied with the device you purchased, or they can be found available on the internet site of the respective producer.
You should make sure that you check online for a new version of drivers at least once a month and if you find one, the old one has to be uninstalled before the new one takes its’ place.
Without drivers your computer only has basic functionality and the performance will lack badly in certain areas. So, if your computer isn’t working properly, the drivers of the main components should be the first to check.
