If you're used to DOS and Windows, and especially Windows-3.1 (a mere 6 years ago), the following correspondences can be made: kernel = msdos.sys shell = command.com gui = windows Even under Windows9x, those elements are still there. Under the typical Unix, the elements look like: kernel = vmlinuz (Linux), genunix (Solaris), kernel (FreeBSD), etc. shell = sh, csh, tcsh, bash, ksh (tcsh and bash are the most popular) gui = X11R6 + window manager + optional desktop As you can see, the Unix world gives you many more options than the DOS/Windows world. Not only do you get to choose your shell and gui elements, you can also customize your kernel. If you're a pessimist it will sound like you get your choice of ropes to hang yourself with. If you're an optimist it will be more like a candy store with something new and tasty every minute.
