Kernel the "kernel" of an operating system is the core section or sections that run in a privileged mode, performing the sorts of operations that you wouldn't normally want to let a user deal with - the idea is that the kernel is a secure, known piece of software which is allowed access everywhere, while other more experimental or replaceable parts of the OS can be limited to their own playpens - for example, if you are writing a driver for a new video card, it's nice to be certain that no matter how much the user lies to your software, he's still not going to be able to get it to write all over your hard disc!
exactly what goes into the kernel varies greatly from OS to OS; NT4, for example, puts quite a lot of the OS into the kernel (including the video drivers!), while other "microkernels" may contain the bare minimum task and memory management
