Explain what a device driver is and the types of drivers. Then describe in detail how a device driver is written and integrated into Linux (include the necessary data structure descriptions) and detail how a device driver is loaded.

The Linux operating system consists of the Kernel some other minor components and then a large number of Device Drivers. Device drivers are the key to how various hardware devices interface with the computer.

Task:

Explain what a device driver is and the types of drivers. Then describe in detail how a device driver is written and integrated into Linux (include the necessary data structure descriptions) and detail how a device driver is loaded. You should include a description and even pseudo code of a skeleton device driver. Describe how the hardware and how the application program can interact with the device driver. Conclude with the roll device drivers play in Linux.
