    13 <p>Device drivers provide a mechanism for applications and other operating

    14 system functions to access hardware devices without needing to know

    15 how each specific piece of hardware works. In addition device drivers

    16 may be written so that part of the device driver is user-side space

    17 and the rest is kernel-side so that the device driver can access shared

    18 memory and resources that belong to the Kernel.</p>

    20 this documentation is for</title><p>There are two main sets of users

    21 for device drivers:<ul>

    22 <li><p>Application developers that want to use device drivers</p></li>

    23 <li><p>Developers that need to create or amend device drivers.</p></li>

    24 </ul></p><p>This documentation set is aimed at the second category

    25 of users. If you are an application developer and want to use a particular

    26 device driver, then you should search for, and read the documentation

    27 for that specific device driver.</p></section>
