To communicate with hardware in your computer, you need to make sure the proper hardware is loaded. The kernel is involved heavily in this task because it loads the necessary drivers to communicate with hardware devices. The kernel is the heart of the operating system; it is the software layer that sits directly on top of the hardware in your server and makes it possible to do anything with that hardware. On SUSE Linux Enterprise Server, you are working with a default kernel in which certain functionality is enabled and other functionality isn't enabled. In this chapter, you will learn about the roles of the kernel and udev for hardware management.
