Device drivers: why are they important and how do you work with them?

A “device driver” is a tiny piece of software that instructs the operating system and other applications on how to interact with hardware.

Printer drivers, for example, instruct the operating system, and thus the software in which the thing you want to print is open, on how to print data on the page.

Sound card drivers are required so that your operating system understands how to convert the 1s and 0s in an MP3 file into audio signals that your sound card can send to your headphones or speakers.

Video cards, keyboards, displays, mice, disc drives, and other peripherals all follow the same general principle.

Continue reading to learn more about why drivers are necessary, as well as some other examples, as well as how to keep your drivers up-to-date and what to do if they stop operating correctly.

How do device drivers work?

Consider device drivers to be translators between a program and a device that the program wishes to use in some way. Because the software and hardware were designed by different people or firms and speak two distinct languages, they must communicate through a translator (the driver).

To put it another way, a software program can supply information to a driver that explains what it wants a piece of hardware to perform, information that the device driver understands and can subsequently implement using the hardware.

Device driver compatibility

Most software applications don’t need to know how to deal with hardware directly because of device drivers, and a driver doesn’t need to provide a full application experience for users to engage with. Instead, the software and driver must merely understand how to communicate with one another.

Given the practically infinite amount of software and hardware available, this is a fairly excellent deal for everyone concerned. Making software and hardware would be nearly impossible if everyone had to know how to connect with everyone else.

Aside from the fundamental software-driver-hardware interaction, there are a few more instances that include (but don’t involve) drivers that are worth mentioning.

While it’s less common these days, certain applications can connect directly to certain types of hardware without the need for drivers! This is typically only conceivable when the software sends relatively basic instructions to the hardware, or when both are manufactured by the same firm, although it may also be considered a built-in driver scenario.

It’s perfectly reasonable to ask if you should upgrade all of the available drivers. Should you obtain all 10 driver updates or just a handful if your computer, the hardware manufacturer’s website, or a driver updater utility informs you that there are 10 compatible with your system? Is it significant which one you use?

The simple answer is no. You do not have to install every driver update that is recommended to you. There are two instances in which you might want to update your driver:

  1. If the hardware fails to function,
  2. If you’re looking for new features,

It’s advisable to just update a device driver if it’s not working right now. If you’ve installed a printer but it won’t interact with your computer, acquiring the right printer driver will only help—it’ll finally allow you to print. However, if the printer was operating properly before you updated the driver, there’s a chance it simply will not work any more, and even if it did update smoothly, you’ll have gained basically nothing.

The other reason is that if you want to get the most out of your device, installing the most recent driver is the only way to access the most up-to-date features.
