Which of the following statements are true about a device driver? Each correct answer represents a complete solution. Choose all that apply.
A . Device drivers are software-dependent and do not depend on operating systems.
B . It allows higher-level computer programs to interact with a hardware device.
C . It is a program or software that controls a particular device.
D . It works as a translator between the device and the operating system and programs that use the device.
Answer: BCD
Explanation:
A device driver is a program or software that controls a particular device. It works as a translator between the device and the operating system and programs that use the device. It provides an interface between a hardware device and operating systems and application software.
It allows higher-level computer programs to interact with a hardware device. When an application needs data from a device, it requests the data from OS, which in turn, send a command request to the device driver.
Drivers are hardware-dependent and operating-system-specific. They usually provide the interrupt handling required for any necessary asynchronous time-dependent hardware interface.
