Excerpted from OS X Mavericks Pocket Guide by Jeff Carlson

Praising the virtues of OS X compared to Microsoft Windows can be entertaining, but in reality, some people need to use Windows; for example, if their business requires Windows-only software. A great but often overlooked feature of OS X is Boot Camp, a technology that enables you to install and run Windows on your Mac. Mavericks doesn’t include a copy of Windows, of course. Boot Camp is just a framework for installing Microsoft’s operating system. But it’s not running in emulation: Without Apple’s distinctive hardware styling, you wouldn’t know you were using a Mac. Although Boot Camp doesn’t allow it, programs such as VMware Fusion and Parallels Desktop for Mac even let you run OS X and Windows simultaneously. In fact, both can use your Boot Camp partition as the Windows environment, without your having to log out of OS X. (If you don’t need to start up your Mac in a Windows environment, consider bypassing Boot Camp and instead installing Windows using one of those programs.)
