In this post, you will know what drivers are and what role they play on your PC and why you should update the outdated drivers, and the methods to update your drivers.

#1 Computer driver definition

A computer driver is a computer program or a string of code that facilitates communication between a hardware component or software application and an operating system (OS) and it operates or controls a specific type of device connected to a computer.

For example, your mouse, DVD drive, video card, and keyboard all use drivers to make your operations work. If you’re using your computer without any trouble, which means you probably have some drivers already installed and working well.

After all, device drivers are translators, enabling your Windows to ask hardware or software to do what you want. If your PC is without drivers, your computer’s hardware and software won’t function properly, and in some cases, they won’t function at all.

#2 What are the functions of drivers on a computer?

To understand how drivers work, you can imagine you are trying to play a videotape on your PC. Maybe this operation you have done many times before, but you do not consider how your PC did it and why you could enjoy that video so successfully. This part will tell you how important your drivers are on PC.

When you play this video on a PC, the application or software you play this video on sends your command request to your operating system (your Windows system). The operating system must then send requests to other components of the computer to help you execute commands, so you can watch this video.

So, what you need to play a video will function at this time. The operating system will ask the network card to cache the video, send the correct commands to the graphics card to display the video, and communicate with the sound card to play the audio from the video.

The OS sends all these requests to the drivers associated with the needed device, and the driver for each device will know exactly what to do.

For example, the network card driver knows what data to transfer, the graphics card knows what to display, and the sound card knows what sound to play. So, when these commands are finished, your video will be displayed well on your PC.

Your computer can fulfill all your requests and commands because the operating system knows how to ask the device to do its work through drivers. Computer drivers help your operating system use your hardware correctly.

Every piece of hardware has its own driver, usually, the driver is written by the hardware manufacturer. Without drivers, some hardware may not work at all, while others may only provide basic functionality.

So only with drivers, your PC functions well.

#3 Why do we need to update computer drivers?

Driver updates are available in many software vendors’ repositories. But is it really that important to have the latest computer drivers? The answer is of course yes.

Driver updates can fix security and compatibility issues, bugs, and broken code, and sometimes even add new functionality to hardware. Another key benefit of keeping device drivers updated is that you can use your PC without any worry.

Outdated drivers are security risks and can make your computer vulnerable to hackers and malware. Is that horrible? Outdated drivers represent serious weaknesses that any competent hacker can easily exploit, which means you open your secret door to them so that they can easily steal your personal information.

Device drivers are generally safe after their initial release and update, but after a while, hackers find any weaknesses that may exist in the software code and start attacking them. This is why you must keep your drivers updated.

Often, device manufacturers identify glitches or errors and then release driver updates to correct them. New advancements are made all the time, and new bugs and threats are constantly being identified by hackers, so driver updates help manufacturers continue to serve customers who buy their products.
