What is the purpose of device drivers in computer system?

Device drivers are software programs that allow the operating system to communicate with and control hardware devices such as printers, scanners, graphics cards, and other peripherals. The purpose of device drivers in a computer system is to enable the operating system to interact with hardware devices and facilitate the transfer of data between the hardware and software components of the system. Device drivers act as a bridge between the hardware and software, translating commands from the operating system into a language that the hardware can understand and vice versa. This allows the operating system to manage and control the hardware devices efficiently, ensuring proper functionality and optimal performance.
