How the Linux kernel works

How the Linux kernel works | TuxRadar: "In depth: My trusty Oxford Dictionary defines a kernel as 'a softer, usually edible part of a nut' but offers as a second meaning: 'The central or most important part of something.' (Incidentally, it's this first definition that gives rise to the contrasting name 'shell', meaning, in Linux-speak, a command interpreter.) In case you're a bit hazy on what a kernel actually does, we'll start with a bit of theory."
