An operating system is a computer program that manages the hardware and software resources of a computer.\n\nThe kernel is the central component of most computer operating systems.\nThe difference is that Kernel is central to the OS, but there are also other components which help the kernel. ( Like observing the user input )

The first true digital computer was, apparently, the German Zuse Z3 (and here I thought it was ABC...). ( http://en.wikipedia.org/wiki/Digital_computer#History_of_computing )\n\nFrom Wikipedia: "The first computers did not have operating systems. However, software tools for managing the system and simplifying the use of hardware appeared very quickly afterwards, and gradually expanded in scope. By the early 1960s, commercial computer vendors were supplying quite extensive tools for streamlining the development, scheduling, and execution of jobs on batch processing systems. Examples were produced by UNIVAC and Control Data Corporation, amongst others." ( http://en.wikipedia.org/wiki/Operating_system#History )\nSo, yeah, today mostly all computers have an OS.\n\nFouth Generation? Never really heard of it, but Googling brought this up: http://www.ipp.mpg.de/de/for/bereiche/stellarator/Comp_sci/CompScience/csep/csep1.phy.ornl.gov/ov/node13.html\n\nThe two most commons OSs today are Windows-like (Windows XP, Windows 2000, upcoming Windows Vista, etc) and Unix-like (UNIX, GNU/Linux, Mac OS X, etc).\n\nAgain, Wikipedia: "An operating system (OS) is a computer program that manages the hardware and software resources of a computer. At the foundation of all system software, the OS performs basic tasks such as controlling and allocating memory, prioritizing system requests, controlling input and output devices, facilitating networking, and managing files. It also may provide a graphical user interface for higher level functions."

The literal answer is that a "windowing" operating system was the term around at the time Microsoft developed the first version of windows. Deskview had long before had it's own windowing system and Unix had X. The Apple of course also had a well developed GUI at the time. Windows being a view to a application/stream of data. Deskview, Apple, IBM and all the other vendors that made multi-tasking OS's back then called these views windows. So Microsoft with typical origionality just called their OS Windows. \n\n\nMore realistically windows means look but don't touch. It has a we'll do it for you and we know better than you kind of attitude built throughout the OS.

click the start button in the lower left hand corner. Click on run.\nType in winver and press enter, that will give you your exact operating system.\n\nPersonally I think firefox is a better browser anyway though.

Operating System Software is the basic foundation software that your PC needs in order to work properly.  Without an operating system the PC wont function.  It can be compared to the human brain, without the brain the body is useless, or so to speak.  I hope thats useful for you...

UNIX and LINUX are operating systems the same as Windows, MAC and DOS.  UNIX is usually reserved for PA-RISC or ITANIUM processors in high end servers.  LINUX is an open source version of UNIX.

Windows Vista is the next version of Microsoft Windows operating system, superseding Windows XP. It was previously known by its codename Longhorn, after the Longhorn Saloon, a popular bar in Whistler, British Columbia (see the other Microsoft codenames). The name "Vista" was unveiled on July 22, 2005. According to sources, the scheduled release date for Windows Vista is July 23, 2006. That release date is only scheduled for PC vendors so that systems will be made Vista-ready before Christmas. The general public availability is projected to be around late September to early October 2006, five years after the release of Windows XP, making this the longest time span between releases of desktop versions of Microsoft's Windows operating system.

Unix is not one single operating system, but rather a family of similar ones.\n\nThere are three (in my opinion) main groups of Unix-based and Unix-like operating systems:\n\n1. Enterprise-level commercial Unix operating systems\n2. Linux and BSD, free Unix-like operating systems\n3. Mac OS X, a BSD-based operating system from Apple\n\nI'll try to compare each group with Windows XP.  If you want more details, please be more specific with your question.\n\n1. These are traditionally very expensive operating systems that are very stable and secure, but they're geared more towards businesses than consumers/home users.\n\n2. Linux is a free and open-source project that aims to provide Unix-like functionality and security to the general public.  Like Unix, Linux is not one operating system but a family of similar "distributions" that share a common central core (called the "kernel").  There are differences between the distributions, but taken as a whole, the following can be probably be said about Linux versus Windows XP:\n\n* Linux is, basically, an attempt to bring a Unix-like operating system to the masses.  It combines the power and security of Unix with the extensibility and price attractiveness of open-source software.\n\n* A default Linux installation with the latest patches is more secure than a default Windows installation with the latest patches.  Both systems can be made relatively secure with proper administration and usage techniques, but Linux is less vulnerable to worms, viruses, spyware, etc. "out of the box".  It is not entirely clear whether this situation is due to inherent security advantages of Linux or due to Windows's overwhelming popularity as a target for malware writers; likely, it's a combination of both.\n\n* The majority of software for Linux is both open-source and free of charge.  Most Linux distributions come with a huge variety of free software and additional ones can be easily downloaded from the Web.  A relatively complete suite of personal desktop applications (including web browser, email client, office programs and more) for Linux can be downloaded for free and installed in a few hours' time, whereas an equivalent setup for Windows would usually cost several hundred dollars in licensing fees.\n\n* Linux comes with a lot of powerful software.  It has, for example, an extremely powerful command-line interface that puts Windows XP's DOS box to shame.  However, except for the most basic computing tasks, Linux can be very difficult to use and especially to troubleshoot.\n\n* Consumer computer hardware is usually designed and tested for Windows.  Linux support is less common and rarely guaranteed; Linux relies on its community supporters to provide hardware support.  Generally speaking, Linux has worse support for modern hardware than Windows.  Some distributions, however, may work better with older, "legacy" hardware.\n\n3. Mac OS X is Apple's attempt to combine the power and security of Unix with the ease-of-use of the Macintosh operating system.  Compared to Windows XP, the following can be said:\n\n* OS X is just as easy, if not easier, to use than Windows XP.  However, as with any unfamiliar product, there may be a slight learning curve for long-time Windows users.\n\n* OS X, like Linux, is relatively free of the virus and adware problems that often plague Windows PCs.\n\n* OS X has fewer hardware issues than Linux or Windows, as long as you stick with products that are either made by Apple or designed for the Mac.\n\n* Macs and OS X software in general can be very expensive and not as widely available.\n\n* OS X does a very good job of hiding the underlying Unix system from its users.  It provides an user-friendly "front" to its complicated innards, resulting in a system that, for the most part, "just works".  However, the power of the Unix system and command line is still there for users who want to access

The first computers did not have operating systems. However, software tools for managing the system and simplifying the use of hardware appeared very quickly afterwards, and gradually expanded in scope. By the early 1960s, commercial computer vendors were supplying quite extensive tools for streamlining the development, scheduling, and execution of jobs on batch processing systems. Examples were produced by UNIVAC and Control Data Corporation, amongst others.\n\nThrough the 1960s, several major concepts were developed, driving the development of operating systems. The development of the IBM System/360 produced a family of mainframe computers available in widely differing capacities and price points, for which a single operating system OS/360 was planned (rather than developing ad-hoc programs for every individual model). This concept of a single OS spanning an entire product line was crucial for the success of System/360 and, in fact, IBM's current mainframe operating systems are distant descendants of this original system; applications written for the OS/360 can still be run on modern machines. OS/360 also contained another important advance: the development of the hard disk permanent storage device (which IBM called DASD). Another key development was the concept of time-sharing: the idea of sharing the resources of expensive computers amongst multiple computer users interacting in real time with the system. Time sharing allowed all of the users to have the illusion of having exclusive access to the machine; the Multics timesharing system was the most famous of a number of new operating systems developed to take advantage of the concept.\n\nMultics, particularly, was an inspiration to a number of operating systems developed in the 1970s, notably Unix. Another commercially-popular minicomputer operating system was VMS.\n\nThe first microcomputers did not have the capacity or need for the elaborate operating systems that had been developed for mainframes and minis; minimalistic operating systems were developed. One notable early operating system was CP/M, which was supported on many early microcomputers and was largely cloned in creating MS-DOS, which became wildly popular as the operating system chosen for the IBM PC (IBM's version of it was called IBM-DOS or PC-DOS), its successors making Microsoft one of the world's most profitable companies. The major alternative throughout the 1980s in the microcomputer market was Mac OS, tied intimately to the Apple Macintosh computer.\n\nBy the 1990s, the microcomputer had evolved to the point where, as well as extensive GUI facilities, the robustness and flexibility of operating systems of larger computers became increasingly desirable. Microsoft's response to this change was the development of Windows NT, which served as the basis for Microsoft's entire operating system line starting in 1999. Apple rebuilt their operating system on top of a Unix core as Mac OS X, released in 2001. Hobbyist-developed reimplementations of Unix, assembled with the tools from the GNU Project, also became popular; versions based on the Linux kernel are by far the most popular, with the BSD derived UNIXes holding a small portion of the server market.\n\nThe growing complexity of embedded devices has a growing trend to use embedded operating systems on them.
