Network Operating Systems differences and/or Similarities

What are some some differences and/or similarities between network operating systems?  Which two would you reccommend?  and Why?

      Perferably these:  Linux, Microsoft 2000, MVS, OS/400 and AIX.

I have one, namely, why are all computer operating systems now called network operating systems?

>  It all depends on you purpose, environment and applications.......

The different products exist because there are different needs.

Why not include Novell? Why not Sun?

MVS is a system permitting multiple users to login at the same time. No version of Windows does that, but they do try to collect more from offering Terminal Services.

Netware and Solaris remain very important to many people who need more than an alternative to Mosaic that runs more value added insecurity

I recommend the one that meets your needs.  Each OS has its specific strengths and weaknesses, some are technical and some are are not.  What are your needs?  What is the experience of your staff?  Although I like Linux, I would not recommend it if your staff only has Windows experience or if you must run applications that only run on Windows.

MVS (now called z/OS) can do things on a scale that most OS's only dream about.  Want to write your own custom applications that support 10,000 (or more) concurrent users?  z/OS running on zSeries mainframes will do it.  Want to run and generic e-mail sever for 500 users, well z/OS may be a bit expensive.

Unless you have an applications that you must run on AIX, I would choose Linux over AIX.  Any Unix/AIX admin can pick up Linux easily and Linux is a bit less expensive than AIX and can run on less expensive hardware.  However AIX clustering is a bit more stable and mature than Linux clustering.

OS/400 is suppose to be easy to support and maintain.

Nice try.

wikipedia has made me laugh again.

A Network Operating System is any Operating System that connects more than one computer.  Very simple and very precise.  It dates to the connection of the first two computers ever connected; this forms a network, without question.  Funny just how many people will take credit for a term that they did not coin.

The bigger NOS are just bigger and usually connect more computers, but two is sufficient to define a NOS.

Under that definition, all computers today are NOS.

Some bigger, some better, with Linux and Windows Server in the lead because of usage.  UniSys is actually the best, with close seconds of perhaps Cray, IBM, and others, followed by the pc ones, Linux, Windows, etc..

For your PC, either Linux or Windows are probably the best, with a combination of the two being even better.

Next steps: NCOS [Network Compiler Operating Systems] and GENN Systems [GENeration N Systems].

NCOS is a Network Operating System with a built in Compiler that can compile modules on the fly and integrate them seemlessly into existing programs, including the NCOS itself.  It's the Operating System that adapts and grows as needed without a complete recompile.

Linux and Windows are close to the NCOS concept, but not exactly quite there yet.  It is expected that they will reach this point within 10 years using current 64-bit system architecture.  For now they reamin NOS.

So click on 'edit'
Try here for more:

may  u please send  me information on different types of network operating systems preferbly windows 2000 server, unix and linux ., i need to make a comparison , im looking for the best NOS to use which can effectively support 10 000 users.

Sorry, DOS is not NOS even where two or three DOS machines are connected.

HaHaHa, those are NOS? And you complain about Wiki?

Yes, they are Network Operating Systems.

" Sorry, DOS is not NOS even where two or three DOS machines are connected."

That's because you don't know what Disk Operating System [DOS] means.  Apparently, Drs. Weiss and Wirth taught me a little differently about the way their inventions [disks, the fathers of all hard drives] stored code and data, Eckert & Mauchly added the mechanism to boot from the disk, and the first Disk Operating System was born.

IBM didn't have this concept down until late in the 1970's, they were still running batch.

All of the companies you mention either didn't exist, or, they were waiting to be taught how to network, especially Digital Equipment Corporation [pdp11 on up].  Vax, if you look it up, is a clone of UniVac, see the similarities to the first network comptuer, Illiac?

The best one to handle 10,000 accounts comes from the company that first had 10,000 accounts on a network.  Whether it's their mainframe, hybrid, or microprocessor based, which is why AOL, Microsoft, and your government are still using them.

And they handle millions of accounts, perhaps more than a billion, worldwide.

Was that funny to you?
