What is the main purpose of device drivers?

Device drivers are small programs that help hardware talk to your operating system. Each device needs its own driver so Windows or Mac knows how to use it. Drivers translate between hardware language and software language.

Without drivers, your printer wouldn’t print or your graphics card wouldn’t display properly. Applications run separately from drivers. Security software protects against viruses, not drivers.

Think of drivers as interpreters helping two people speak different languages. They make hardware and software understand each other perfectly.
