What did Richard stallman mean when he stated that GNU was a free operating system?
As most people will tell you about software licensing, the definition of "free" in this case is freedom from licensing restrictions, not as in free-of-charge (in which is derived from the original definition ["...not as in free beer..."] to make it more all-ages friendly).
First of all, Unix (and even Linux) is NOT virus free. Although rare, there are viruses for such systems. One of the primary reasons that Unix / Linux do not get as many viruses is that the ability of different users is limited. Non-technical users will be restricted in their ability to install…, run, or modify software. More experienced users will usually be given more privileges. Without inexperienced users installing software at a whim, over 90 % of the threat of viruses and malware is removed. Linux is even further protected against viruses because Linux is by nature a heterogeneous platform. To be effective, the program would have to be capable of affecting multiple versions of the kernel, and use exploits in a variety of programs. (MORE)
The Systems Engineering group at NI has developed a set of data logging and monitoring example LabVIEW code for test cells and similar uses. The example application is configuration-driven (point/click, drag/drop), and suitable for use with DAQmx, Fieldpoint, and custom (VI-based) I/O servers. It il…lustrates a method for building LabVIEW DSC-based client/server systems as well as various styles of client displays. . 2. OLTP (Online Transaction Processing). Online reservation systems in traveling agencies are an example of OLDP. In these kind of systems there is a central system and there are many other machines that are connected to the central system from different geographical locations.. An example of distributed computing is http://wiki.answers.com/wiki/BOINC , a framework in which large problems can be divided into many small problems which are distributed to many computers. Later, the small results are reassembled into a larger solution. . Other examples of Distributed system are projects, that include the http://wiki.answers.com/wiki/Stanford_University http://wiki.answers.com/wiki/Chemistry Department http://wiki.answers.com/wiki/Folding%40home project, which is focused on simulations of http://wiki.answers.com/wiki/Protein_folding to find disease cures and to understand biophysical systems; http://wiki.answers.com/wiki/World_Community_Grid , an effort to create the world's largest public computing grid to tackle scientific research projects that benefit humanity, run and funded by http://wiki.answers.com/wiki/IBM; http://wiki.answers.com/wiki/SETI%40home, which is focused on analyzing radio-telescope data to find evidence of intelligent signals from space, hosted by the http://wiki.answers.com/wiki/Space_Sciences_Laboratory at the http://wiki.answers.com/wiki/University of California%2C Berkeley; and http://wiki.answers.com/wiki/Distributed.net, which is focused on breaking various cryptographic ciphers. . 5. Groupware applications like Lotus Note. In the above systems there are usually clients and servers and there is network in between. On the server side there may be databases and database management systems and on the client side there may be any number of clients with different applications. Client applications may be thick or thin. Thin client programs have very little business logic in them like an applet or an HTML browser but thick client programs have a lot of business logic and computations in them like banking or simulation applications..

Windows 10 is currently a free operating system and can bedownloaded on the Microsoft website, Ubuntu OS is also a freeoperating system, it can be Downloaded from the Ubuntu websiteUbuntu.com/download
Operating system software is a program like Windows, i.e. a program you must have to run a computer. Other software you choose to run is called applications software. Programs like Excel, Word or Internet Explorer are application software. Over history there have been lots of different operating sys…tems. The first one for PCs was called DOS, later came Windows. IBM mainframe computers had three operating systems called VSE, MVS, and VM. Apple has their own operating system. Usually computers are sold with operating system software since you need it to do anything. Most application software is sold separately since you may not want to do the application. There is a disturbing trend in the computer industry to load up computers with trial application software which many people do not want. They do this because the computer manufacturer is paid by the application software vendor to do this. (MORE)
Yes. A very large variety of operating systems are available free of cost, and many with source code available. Operating systems available free of charge, for any purpose, with source available: . Linux - Unix-like OS . FreeBSD - Unix-like OS . OpenBSD - Unix-like OS . NetBSD - Unix-like… OS . FreeDOS - MS-DOS clone . ReactOS - Windows 2000 / XP clone (in alpha, not suitable for daily use) . Haiku - BeOS clone (in alpha, not suitable for daily use) . AROS - AmigaOS clone (lacks a web browser and good device support) . KolibriOS - Floppy-size OS with a crude GUI . Syllable - general desktop OS; Amiga-like. . OpenSolaris - open-source codebase of Solaris (see below) Operating systems available free of charge for personal use, without complete source: . Solaris 10 - Unix implementation from Sun Microsystems. Useful as workstation / server; lacks comprehensive hardware support. . BeOS Personal Edition - multimedia-oriented desktop; doesn't work on most newer computers. . DR-DOS - MS-DOS clone . MenuetOS - Floppy-sized OS with GUI. . QNX - realtime / embedded OS; highly responsive environment, though mostly lacking in applications (you were supposed to write your own!) Answer: Why you buy costly OS from Microsoft or some other companies. There are some othe popular operating system that work same like Microsoft' OS. Most of the OS are freely available to download and run on private machines. Some are 1. DOS 2. RxDOS 3. Ubuntu 4. ReactOS etc You can find and download more free OS from the link that I have posted in the related links with this question. (MORE)
Spooling refers to a process of transferring data by placing it in a temporary working area where another program may access it for processing at a later point in time..
This is impossible to answer conclusively. In addition to the fact that no operating system is perfectly suited to all tasks, the word free itself is up for debate. Free can have several different meanings to different people. To many people it means that it is free of any monetary cost. To oth…ers, free means that something lacks any restrictions on what you can or cannot do with it. In operating systems, an operating system that restricts what you can do with it (such as modify the code or sell it) is considered proprietary . The only free operating systems that do not impair your rights to sell or modify them. Even within free systems, there is debate. Systems under licenses like the GPL force you to make any changes you make to a program you release to the public freely available. Other licenses like the BSD or MIT license allow you to keep the changes you make proprietary , and even re-license under a different license without making the source available. Comparison of freeware proprietary operating systems The operating systems that are considered the best in their field are listed below. More than one will still need to be listed, as there are still things about them that would make them unsuitable for a large number of people. Desktop / Workstation MorphOS - MorphOS is a desktop operating system with a multimedia-oriented operating system modeled after AmigaOS. Limitations: available only for workstations with PowerPC processors. Limited selection of applications. No memory protection. BeOS - Multimedia desktop with many features considered rather advanced in its time. Fast microkernel design. Interface is considered by most to be very easy to learn. Decent homebrew community. Limitations: Company went out of business. Limited selection of apps. Often does not work on computers newer than 2004. QNX - Fast and responsive on extremely low-end / older hardware. Highly reliable and compact. Applications from many other systems like Linux are easily ported to it. Limitations: designed for embedded use, not desktop. Lacks many basic desktop features for above reason. Installation requires (free) registration at comapny's website. Commercial use would require purchase of a (very expensive) license. DR-DOS - 100% compatible MS-DOS clone. Includes many features that MS-DOS didn't support. Limitations: does not come with a graphical user interface. Only capable of single-tasking without some complex TSRs. Limited support for modern hardware. Server QNX - POSIX-compliant; highly secure. Many web server packages have already been ported to it. Limitations: commercial use would require purchase of a (very expensive) license. Embedded QNX - realtime, portable, highly reliable. Limitations: commercial use requires purchase of a (very expensive) license. Comparison of free and open-source operating systems Desktop / Workstation Linux - Large selection of applications. Support for a broad range of hardware, and runs on systems both old and new. Highly reliable and secure. Growing community focusing on increasing ease of use. Limitations: Limited selection of commercial software. The large number of choices in distros and desktop environments can be daunting. Some devices do not work in Linux, simply because the vendors will not release hardware specifications. FreeBSD - large selection of software (pretty much whatever runs on Linux). Less restrictive licensing (BSD). About 95% of hardware supported in Linux is supported by FreeBSD. Highly secure and reliable. Limitations: awkward installation of programs (except PC-BSD variant). Limited selection of commercial software. Community is highly devisive and prone to fragmentation. Some hardware devices do not work in FreeBSD due to lack of hardware documentation. Server Linux - reliable and secure. Very large support for commercial server software. Scales well across multiple cores and handles multi-threading well. Limitations: no support for some proprietary Microsoft extensions (like ASP). FreeBSD - highly reliable and secure. Very large selection of commercial server software. Decent performance and hardware scaling. Limitations: no support for some proprietary Microsoft extensions. No major commercial backers. Embedded Linux - excellent documentation and reliability. Easily portable. Highly modular (can have unneeded components removed). Limitations: size still cannot be reduced enough for some types of devices. eCos - designed from groun up for emdedded use. Highly portable and POSIX compliant. Limitations: ? (MORE)

When a new peripheral is added, that …device's driver is installed into the operating system (MORE)
There are loads and loads of free operating systems, most of them are distributions of Linux which come in many forms, perhaps the most popular of these being ubuntu due to it's ease of use. However there are other free OSs such as FreeBSD and a project that aims to make a free clone of windows XP.
It means that there is no operating system installed on your computer, or it is in a non-bootable configuration.
Pros are good things about something. Cons are bad things about something. So the pros and cons of an operating system are the good and bad things about it.
Actually, Yes. There are many operating systems out there which have no possibility for a malware to be written. THESE CAN AND WILL GET VIRUSES: Microsoft Windows is a real disadvantage in this, as any program (including malware) can be run and installed WITHOUT the user's permission, viewin…g this website with a bad line of HTML code will (theoretically) destroy your windows PC. Linux is like this as well, however there is a real lack of LINIX programmers, sunce there are so many adaptations of LINUX around and thee tiny market share they own. Most Smartphones: These will get viruses as quickly as windows will, for owners of S60 (the most used smartphone in the world) this is a severe problem. THESE MIGHT GET MALWARE IF YOU ARE AN IDIOT: Mac OSX: Mac does not get malware simply from viewing a site, but DO get malware if you really go out of your way to put it on. You will have to manually download a file from somewhere (an untrusted site), wait for the download, manually install the software, allow extra permissions to the file system, do this, do that... virtually impossible Regular Phones: These run the J2ME Operating system, which has to be configured to work alike MAC IMPOSSIBLE: iPhone, iPad: Software has to be certified by Apple and downloaded from the Apple website. You can't make your own software (unless Apple gives YOU permission for a hefty sum of cash). You can however get malware is you hack (jailbreak) the iPhone with your computer and install a similar operating system - It is understood that "VIRUSES" are actually a specific type of malware (malicious software) which involved corrupt and coding changed OFFICIAL FILES (totally recoding Internet Explorer 9 to becoming a media Player is an example). I substitute MALWARE for VIRUS as malware is really anything you don't want (like most stuff which steals your credit card details which AREN'T viruses), rather than a specific type of bad software.

\nGNU is a Free Software project which is essential to the Linux operating system. It is a project that provides and distributes a lot of the software which is essential to making a fully-functional operating system distribution based upon the Linux kernel.\n. \nFor example, the Linux tools/comman…ds that allow you to enter and run commands, copy files from one directory to another, compress and uncompress files, search for strings within text files, and mount and unmount filesystems are all GNU-provided tools.\n. \nIn short, GNU is a project which provides a major portion of the base Linux operating system - besides Linux itself which is the kernel and is provided by a separate project. It does not however provide the entire rest of the operating system; primarily just the type of basic tools mentioned above (although a very lot of them).\n. \nSome GNU software has also been ported to run on other operating systems also.\n. \nSome people refer to the Linux operating system as GNU/Linux to reflect the major contribution which GNU provides to that operating system.

In the free software world, there are several uses of the word "free." The two main ones are "free as in speech" and "free as in beer." Free as in speech means you are relatively unfettered in what you can do with the software. You can modify it, use it for whatever you want, and give it to others (…or even sell it). Free as in beer means that you can obtain it for no monetary cost. Richard Stallman originally envisioned GNU to be free as in speech. At the time he started the project (in 1983), internet access was slow and expensive, high-capacity storage devices weren't readily available, and very few people had a personal computer. It would have been infeasible to offer GNU on a gratis basis. Stallman actually used to charge $150 for a tape with the GNU software on it, plus $15 for a manual. (MORE)
