Windows CE Interview Question:

Do you know What is Device driver?

Submitted by: Administrator

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:
a) Device I/O Address (Physical Hardware -> Logical OS based address)
b) Interrupt that the device generates and its handler (the driver)
c) A software Handler to manage the read write operations to and fro from the device.
