There are many operating systems.  By modern, I'll assume you mean still widely used.  Even looking at it from this point-of-view: Wikipedia lists far more than 50.\n\nI recommend looking at the links below for an overview of not only what they are called, but what makes each of them different or unique.\n\nEnjoy :-)

Yes, there's been many for several weeks.  The beta 2 (most people can get their hands on) is going to be released tomorrow.  You have to sign up though and if you haven't already, you probably aren't going to get it.  Not to mention you need quite a bit of experience with computers to run a beta os.  Just a guess, but if you haven't heard of it yet, you probably don't have the experience...

There are two major markets for operating systems - desktop and server. While Linux made some advances on the desktop operating systems market, they have been minimal and not quite impressive.\n\nOn the server market both Windows and Linux vendors increased their shares, mainly at the expense of UNIX vendors and a company called Sun Microsystems.\n\nWhile many people view the operating systems as vying for the market, Linux and Windows are used by quite different markets for quite different purposes, so perhaps the competition is not quite there.

using the same license for all 15 computers is not wise because Microsoft recently updated their Windows genuine advantage program to exclude the other 14 computers from getting updates. The program then accuses you of piracy, and posts signs all over your computer that "this copy of windows may be counterfeit (including posting signs on the boot and lo gin screens)\n\nit may be sensible to go with a version of Linux, depending on the needs of the office.\n\ncheck out all the links below (1 copy of xandros can be installed on all the computers and is the most compatible with windows applications)

These links found in Google may help:\n\nhttp://www.google.co.uk/search?hl=en&q=what+is+multi+user+operating+system&btnG=Google+Search&meta=\n\n\nA multi-user operating system allows more than one user to utilize the computer's resources simultaneously. A multi-user operating system ensures that the requirements of various users are balanced. It makes sure that each of the programs they are using has sufficient and separate resources. A problem with one user doesn't affect the other logged-in users. Examples of multi-user operating systems are UNIX, VMS, and mainframe operating systems, such as MVS. \nNote that the popular PC operating systems such as Windows 2000 and Novell Netware aren't true multi-user operating systems, although they can support hundreds or thousands of networked users. The system administrator is the only user for Windows 2000. The network support and all remote user logins are, in the overall plan of the operating system, a program being run by the administrative user. \nMulti-user operating systems are used for a host of benefits. Security and Cost-effectiveness rank amongst the primary reasons for the same.

An operating system is a very powerful program. It hosts other programs made for it. The operating system is also a very important  piece of software that can communicate with a computer's hardware. Without an operating system, no programs would be able to work unless they're bootable alone (this would be going into a different story). An operating system can use up to about 5 gigabytes of data on your hard drive( so I've heard). Some operating systems can include: Windows, Mac OS X, linux, and others. Some operating systems are made specifically for one purpose for a company. These operating systems are usually not sold to the public and are classified as custom OS's.

An operating system (OS) is the program that, after being initially loaded into the computer by a boot program, manages all the other programs in a computer. The other programs are called applications or application programs. The application programs make use of the operating system by making requests for services through a defined application program interface (API). In addition, users can interact directly with the operating system through a user interface such as a command language or a graphical user interface (GUI). \nExapmples of Operating systems:\nWindows ( XP, 2000, ME, 98 , 95, 3.11 )\nDOS\nLINUX..
