The Importance of Device Drivers in Computers

In computer science, a device driver is usually a software program that acts as a translator or coordinates a specific kind of device attached to the computer or other automaton. It translates device specific signals such as those from a printer to its driver, or from an audio device to its speakers. In addition, it also translates generic signals produced by other devices and communication protocols used by computers. Different operating systems and software programs require different device drivers in order to function correctly. For example, if your printer needs to talk to your audio speakers, then the appropriate device driver will be installed.

Generic character device drivers are driver programs that exclusively translate and control input and output signals for use with software applications. Audio drivers, printing device drivers, video device drivers, and game device drivers are examples of generic character drivers. Some generic character drivers are so general that they may not be able to operate properly with some other software programs, which is why they are specific to particular software programs. They are important because it guarantees compatibility between your operating system and certain software applications. This ensures that your system is able to function properly even without the need for a compatible driver.

Directories containing multiple device drivers can be accessed using an application program like Device Manager. To determine which device drivers are needed for a specific application, select a device from the list that matches the specifications of the application that requires such device driver. In this way, all devices that are needed for a particular application can be quickly and easily identified and subsequently installed. There are several file system drivers available as well, such as FAT32 file system drivers and NTFS file system drivers.
