A driver is fundamentally a piece of software written for a specific device. Its main tasks are to perform I/O's on a device. To do this there are typically WELL defined models for a driver.

Generic description of a driver structure will be:

  1. Device I/O Address (Physical Hardware -> LOGICAL OS BASED address)
  2. Interrupt that the device GENERATES and its handler (the driver)
  3. A software Handler to manage the read write operations to and fro from the device.
