Device and kernel modules
In this episode, we're going to take a deep look at how Linux interacts with hardware and how that interaction is exposed to administrators and applications. One of the defining characteristics of Linux is that hardware is abstracted away from the user, meaning that you don't typically interact with hardware directly. Instead, Linux provides interfaces that allow software to communicate with devices in a very consistent and predictable way. Understanding device management is critical for system administrators because nearly every system problem eventually traces back to hardware or drivers. Whether you're dealing with storage devices, network interfaces, or peripheral hardware, Linux relies on the same core principles to manage all of them. We'll start by examining device files and how Linux represents hardware as files. We'll then move into Udev, which handles dynamic device detection and naming. And then finally, we'll talk about kernel modules and how Linux loads and manages…
