1 PerryLorier 1 Wikipedia defines a "Kernel" as:
3 ;:The central module of an operating system. It is the part of the operating system that loads first, and it remains in main memory. Because it stays in memory, it is important for the kernel to be as small as possible while still providing all the essential services required by other parts of the operating system and applications. Typically, the kernel is responsible for memory management, process and task management, and disk management.
5 which I don't think is a very good definition. A kernel in my mind is something which manages the computers resources (memory, disk, processor time etc) and abstracts the hardware.

24 Remember, you can't boot a kernel by itself, hence the ReligiousWar of [RMS] vs common usage. Attempting to boot "Linux" would result in something along the lines of "Kernel Panic: Cannot find init". Trying to boot what [RMS] calls GNU/Linux would result in the OS we know and love.
