Boot Camp vs Parallels:
The advantage of Boot Camp is that you literally turn your Mac computer into a Windows-based PC. The term “PC” is often mis-associated with the Windows operating system. The term “PC” actually means personal computer and can refer to a Mac computer, Windows Windows-based, UNIX or even a Commodore 64.
Boot Camp is included on Mac computers and is simply a utility that pops up before the operating system. The most common form of Boot Camp is when you are asked to make a choice between the Mac OS and Windows OS. If you choose Windows, you are essentially using a Windows-based PC which will function exactly like a PC that you might otherwise purchase from Dell, Gateway or other PC manufacturers except that it will additionally have the Apple command key which doesn’t function in Windows.
By comparison, Parallels and VMware are virtual Windows environments which means that you are running a virtual Windows environment inside of the Mac OS.
The advantage of a virtual Windows environment is that you can quickly switch back and forth between the Mac OS and the Windows OS. The disadvantage of a virtual Windows environment is that you have to split your RAM and it is a smidgen less stable. If you want to get out of purchasing additional RAM and the Mac OS is of no real importance to you at work, you could take your computer to an Apple Store and have them install Windows for you. As long as you don’t need to frequently switch back and forth between the Mac and Windows OS, you could simply turn your Mac computer into a Windows-based computer which will likely seriously depress the folks at the Apple Store.
