Mac OS X Server gives you everything you need to provide standards-based workgroup and Internet services Pre-emptive multitasking and memory protection, for example, improved the ability of the operating system to run multiple applications simultaneously without their interrupting or corrupting each other. Mac OS X included a number of features intended to make the operating system more stable and reliable than Apple's previous operating systems. On top of this core, Apple designed and developed a number of proprietary closed source components, including the Aqua user interface and the Finder shell. Its core, named Darwin, is an open source, Unix-like operating system, built around the XNU kernel with standard Unix facilities available from the command line interface. Mac OS X was a radical departure from previous Macintosh operating systems as its underlying code base is completely different from previous versions.
