A Canonical Device
Explore the concept of a canonical device to understand how operating systems efficiently interact with I/O hardware. Learn about the device’s hardware interface and its internal structure, including examples like RAID controllers, to grasp how device functionality is implemented through firmware and hardware components.

Let us now look at a canonical device (not a real one), and use this device to drive our understanding of some of the machinery required to make device interaction efficient.
From the figure given above, we can see that a device has ...
