The G5 came with the OS 9 operating system and had a Power PC processor. It was the last edition of Mac OS. The iMac switched to the OSx operating system with the next iMac. There was an education only model G5 that did ship with OSx Panther.
Usually, a new iMac is released between 9 - 12 months after the last major release.
Many original iMac computers work just fine, although if they are running the original OS (Mac OS 8 or 9), then they are most likely out of date from a technical standpoint. While they can still perform as a standalone computer, they may find some difficulty navigating today's internet, since there are few, if any, web browsers still developed for the older Mac OSes.
Mac OS 9 is the old version of Mac OS. Mac OS X was completely rebuilt from the ground up. Except some of the programs. The interface and look is different, but things like Disk Utility and stuff are the same. Terminal is a program that never gets improvements so that's the same too.
Unfortunately No. You should upgrade your OS 9 machine to OS X
As of August 2014, it is not possible for a person to upgrade OS 9 to OSX. A person will only be able to upgrade to OS 9. 2.
You cannot without erasing your hard drive and installing Mac OS 9 from scratch. Even then Mac OS 9 may not run on modern Mac hardware because Mac OS 9 needs the ROM chip to boot. Modern Mac OS X hardware uses EFI to boot the system instead of a ROM chip to boot. Mac OS X v10.0 - Mac OS X v10.4 support Mac OS 9 applications and can run them, you just need to install the Mac OS 9 compatibility program which can be found on the Mac OS X Install CD.
You can upgrade OS 9 to 10.0 , 10.1, 10.2, 10.3, Maybe 10.4
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.
Not sure exactly what you mean. If you mean was OS 9 command-line based, like DOS, the answer is no. OS 9 is a full-GUI OS, just like OS X is. While OS X does have a terminal window so you can access the underlying Unix-based infrastructure, OS 9 had none (and no infrastructure to access via command-line).
Mac OS X is pronounced Mac OS Ten. It follows on from Mac OS 9 which was the last version of what is now known as the classic Mac OS and it saw the introduction of the new UNIX based OS so the Roman numeral X was adopted to mark the change.
mac OS 9 is the previous Apple Macintosh Operating System version, before Mac OS 10, or X as it has been advertised as. Mac OS 9 does not utilize the 'aqua' look of the modern mac interface, but instead uses a chunky grey interface. http://www.iindigo3d.com/macosmacos9.jpg for a preview of the interface of mac OS 9
