Anthony Boyd, Mike Andrews,
An Operating System controls your computer and sets up an environment
for you to work in. The major Operating Systems you can get right now
are Macintosh, Windows, and Linux. Typical things an OS controls: the
look and feel of your system, the menus, the sounds you hear (or don't)
as you open & close things, and how you access the filesystem. For
example, on a Macintosh the menus are always stuck to the top of the
screen. You can't move them. On Windows & Linux, the menus are
usually stuck to the window, and can be dragged around as part of the
window. Windows has a "Start" menu. Other Operating Systems don't.
Applications are the things you do with your computer. These are
usually the things non-geeks care about. This is Microsoft Office or
StarOffice. This is PhotoShop, and Word, and Konqueror, and Netscape.
This is usually anything you install to get some work (or play) done.
When you think about it, the concept is really just about layers. You
have the hardware itself, which doesn't do much alone. You have the
OS, which gives you access to the mouse, the hard drive, and all the
other hardware. And then you have the applications layered on top.
