These drivers are very small lines of code that direct the operating software and other installed software how to communicate with a computer’s hardware. For example, drivers in a printer will tell the operating software exactly how it should print information. The same idea applies to sound card drivers. The drivers inform your operating software exactly how it can translate the electronic signals that make the MP3 file into clear audio signals that can be heard through your speakers.
How Drivers for Devices Operate
A device driver acts like a translator between a particular computer program and the corresponding computer hardware that the program wishes to use. The hardware and software might have been created by different entities, so the driver helps the two to pass messages.
Simply put, software programs give information to drivers to clarify how it wants a piece of hardware to behave. The driver then passes this information to the computer hardware which then fulfills its mandate.
Due to drivers, almost all software programs do not have to know exactly how they can communicate with hardware. Additionally, a driver does not have to include full application features, such as graphical interfaces, for the users to interact with. Instead, the driver and program simply need to understand how they can communicate with each other.
