Can one Upgrade Macintosh Operating System OS X 10.3 to 10.4?

Yes. Mac OS X 10.3 Panther was PowerPC only, so your question must be if you'll be able to install Tiger, which is widely advertised as being Intel-based. The fact is that every new release of OS X, including and following Tiger, is what Apple calls "Universal", which means they run on both PPC and Intel-based Macs. And both versions come in the same Installation Disc, so you won't even have to worry about choosing the right version for your machine. The process of upgrading is actually very simple. Mac OS X was build to be easily upgradable from the start, so you can just replace the system files while keeping your own personal stuff where they are. Of course, you can always do a clean install, and that is actually preferable, but you have both options to choose from. Also worth mentioning, if your hardware is supported you should really consider upgrading to Leopard instead of Tiger. It's not as slow as people think on older machines. In fact, some benchmarks even report it as being faster, probably due to the improvements made on Quartz during the development of Leopard.
