An Insight into the Windows device driver infrastructure

An Insight into the Windows device driver infrastructure
Device Drivers are one of the most dreaded creatures in the world of Windows. Hardware and software issues like driver compatibility, device not recognized, invalid or corrupt device drivers seem to crop up often which wreck havoc on a computer. For most of the Windows users the nitty gritty of the Device drivers are an uncharted territory and require the help of an expert.

The following is an insight into the Windows device driver infrastructure - the fundamental concepts of the device drivers, the devices and driver installation process, the driver types, driver architectural models, the driver classes, and the interaction of drivers with hardware devices, Windows and other drivers to form the windows device input output system.


1. Driver Concepts

In order to provide system stability, security, and standardization in an preemptive multitasking environment the Windows operating system restricts direct access to the system hardware resources and the operating system resources by applications and provides access based on assigned scheduling priorities and defined access control model.

Windows Networking Internals

The Crux of the Windows networking subsystem is implemented in the form of device drivers and this article assumes the reader is adequately acquainted with the fundamental concepts of the Windows device drivers. If not, reading the article An Insight into the Windows device driver infrastructure is highly recommended.

It is said that any evolved whole is greater than the sum of its parts, and that no single thing can be fully understood in isolation from its extended context. The above holds specially good when it comes to the implementation of networking in Microsoft Windows operating system.

Several websites are available which cover the fundamental concepts and theories pertaining to computer networking. Also, various websites including the Microsoft websites Technet and MSDN have an in depth coverage on the various networking technologies used in Microsoft Windows operating system. However, what an amateur techie finds lacking is how the theories and the technologies converge to form the ecosystem of the Windows networking.

The following is the birds eye view on how the conceptual whole of the Windows Networking is created which is greater than the sum of the parts - the technologies that build up the computer networking subsystem in the Microsoft Windows operating system.
