About Device Drivers

A unique class of software application known as a device driver manages a particular piece of hardware that is connected to a computer. A computer needs device drivers to function correctly.

Why is Device Drivers important?

To connect and communicate with particular devices, a computer needs device drivers. They specify the communication channels and techniques used by the computer's operating system and programs to make requests for the device or access it.

Who should take the Device Drivers Exam?

  • Lead Engineer
  • Complex Device Drivers (CDD) Developer
  • Embedded Software Manager
  • Working professionals who want to learn Linux device driver development.
  • Students who have an interest in embedded system software development.
