There are:
10.3 Panther
10.4 Tiger
10.5 Leopard

The Mac OS comes free with a Mac. New versions have a small charge.
The Mac OS series are different versions of Apple Internet capabilities. (like for Windows)
Mac OS 9 software requires Mac OS 9, which was discontinued in 2002, to work. Early versions of Mac OS X came with Mac OS 9 included (referred to as Classic mode) which could be activated from System Preferences. The latest versions of Mac OS X no longer support Classic mode. It will depend upon your specific Mac model whether a version of Mac OS 9 can be persuaded to work.
it is mac os. Their versions are too good and easy for users.
Mac OS X 10.6 (Snow Leopard) and all earlier versions of Mac OS X will support networks.
Boxed versions of Mac OS X do not include the iLife suite which is available separately.
Yes, there is Pencil, and it's free. There are many versions for it like Mac OS or Mac OS X. Personally, I just got it and it sucks.
Mac OS X is supplied on a DVD with every new Mac. Upgrades to new versions of Mac OS X can be purchased from any retailer that stocks Apple software such as Amazon.
Mac OS X is an operating system released by Apple Inc. It is designed for Apple branded computers, which is why you will never see a Dell, or an HP computer run Mac OS X. There are only two important versions of Mac OS X, Mac OS X Server, and regular Mac OS X. Mac OS X server was designed for servers, while regular Mac OS X was designed for most computers. The current version of Mac OS X (10.6) is named Snow Leopard.
Yes. But better to just run OS/X all the time, and rely on VMware Fusion for occasional XP tasks. You can also partition the hard drive so you can run both Mac OSX and Windows fully. VMWare fusion is probably an easier alternative at this point though. In order to run windows you must buy the newest version of VMWare fusion, as well as the newest version of windows.
Sim City 2000 will not run on Mac OS X. It may run in the Classic environment which was included with older versions of Mac OS X but is not included in the latest versions 10.5 (Leopard) and 10.6 (Snow Leopard). An alternative approach would be software that emulates an older Mac such as SheepShaver (See links below) but either way it will probably take some tweaking to get it running.
Apple's Mac OS X. OS X Lion OS X Panther OS X Leopard etc.
