	Howstuffworks "How Operating Systems Work"
		The operating system must make sure that the requirements of the various users are balanced, and that each of the programs they are using has sufficient and separate resources so that a problem with one user doesn't affect the entire community of users.
		Managing all the resources of the computer system is a large part of the operating system's function and, in the case of real-time operating systems, may be virtually all the functionality required.
		For other operating systems, though, providing a relatively simple, consistent way for applications and humans to use the power of the hardware is a crucial part of their reason for existing.

	Operating system - Wikipedia, the free encyclopedia
		As well as the kernel, an operating system is often distributed with system software that manages a graphical user interface (although Windows and Macintosh have integrated these programs into the operating system), as well as utility programs for tasks such as managing files and configuring the operating system.
		Commercially-supplied operating systems are present on virtually all modern devices described as computers, from personal computers to mainframes, as well as mobile computers such as PDAs and mobile phones.
		Mainframe operating systems, such as IBM's z/OS, and embedded operating systems such as VxWorks, eCos, and Palm OS, are usually unrelated to Unix and Windows, except for Windows CE, Windows NT Embedded 4.0 and Windows XP Embedded which are descendants of Windows, and several BSDs, and Linux distributions tailored for embedded systems*.

	Operating System Functions
		The operating system makes these interfacing functions along with its other functions operate smoothly and these functions are mostly transparent to the user.
		System crashes and instabilities - These can happen due to a software bug typically in the operating system, although computer programs being run on the operating system can make the system more unstable or may even crash the system by themselves.
		A system crash is the act of a system freezing and becoming unresponsive which would cause the user to need to reboot.

	Operating Systems Notes
		The core of the operating system is the kernel, a control program that functions in privileged state (an execution context that allows all hardware instructions to be executed), reacting to interrupts from external devices and to service requests and traps from processes.
		Operating systems generally accomplish these goals by running processes in low privilege and providing service calls that invoke the operating system kernel in high-privilege state.
		An operating system transforms the physical world of devices, instructions, memory, and time into virtual world that is the result of abstractions built by the operating system.

	Millennium
		Such an operating system would raise the level of abstraction for developers and users, so that individual computers, file systems, and networks become unimportant to most computations in the same way that processor registers, disk sectors, and physical pages are today.
		The system should be able to reason about its computations and resources, allocating, replicating, and moving computations and data to optimize its own performance, resource usage, and fault-tolerance.
		This would allow the operating system to protect computations from each other, transparently migrate and distribute them, and intercede in their access to resources.

	Linux Online - About the Linux Operating System
		Linux is an operating system that was initially created as a hobby by a young student, Linus Torvalds, at the University of Helsinki in Finland.
		The kernel, at the heart of all Linux systems, is developed and released under the GNU General Public License and its source code is freely available to everyone.
		The operating system can also be incorporated directly into microchips in a process called "embedding" and is increasingly being used this way in appliances and devices.

	The COSA Operating System
		It is the part of the COSA operating system that handles the reactive logic for the entire system.
		An ideal COSA operating system would have no algorithmic processes whatsoever as all objects would be self-processing and would communicate via direct connection pathways, not unlike biological neurons.
		Since the system is driven by change, only the cells that are directly affected by events need to be processed during any given cycle.

	Popular operating systems list, by The Linux Information Project (LINFO)
		The core component, the Hurd (Hird of Unix-replacing daemons) kernel (i.e., the core of the operating system), is still not completed because of its very ambitious goal: to surpass Unix-like kernels in functionality, security and stability while remaining largely compatible with them.
		It is unusual among Unix-like operating systems in that it is built on the Mach kernel, which is also used in Mac OS X. Tru64 was originally developed by Digital Equipment Corporation (DEC) and called Digital UNIX.
		POSIX (Portable Operating System Interface for uniX) is a set of programming interface standards governing how to write source code so that the applications are portable between operating systems.

		As embedded systems (PDAs, cellphones, point-of-sale devices, VCRs, industrial robot control, or even your toaster) become more complex hardware-wise with every generation, and more features are put into them by the day, applications they run require more and more to run on actual operating system code in order to keep the development time reasonable.
