Operating Systems - nt vs unix.

I would like ti receive the difrences between nt and unix
Operating Systems on the folowing issues :
1.      Multi Threads Support.(what is the maximum number  
        of threads support ?).
2.      Supporting number of network boards (what is the
        maximum number supported ?).
3.      Supporting Data Base.

4.      Simplicity of developing tools and debugging.

5.      Security in the operating system level.

6.      Raid support.

7.      Multi Proccesors support (what is the
        maximum number supported ?).

8.      Backup support (what are the backup opportunities).

9.      Memory size – 120 Giga (Is it support by the
        operating system ).

10. Reliability of the O.S. (avoiding crashes).

11. Constrains on hardware (is there any demand for
    specific hardware).

I would like to receive a full comparison between the two
operating systems.
Thank you.

Many of these issues depend on the flavour of UNIX or the hardware, rather than the operating system itself:

1) Depends on UNIX flavour and version.

2) Depends on UNIX flavour, version, hardware, networking software and probably several other things besides.

3) UNIX doesn't come bundled with any database but all the big vendors (apart from Micro$soft) have variants that will run on UNIX.

4) What do you call "simple"?  Some vendors such as Silicon Graphics provide a sort of unified environment for developing and debugging code called Codevision, which is a little like Visual Studio. Some other vendors have similar environments, but they will all supply a compiler, linker and debugger. Many professionals prefer freeware such as the GNU compiler and debugger.

5) Operating system security is roughly comparable for most day to day purposes. I could not comment about military levels of security.

6) Raid support is a feature of the disks, not the operating system.

7) Depends on flavour of UNIX and version and also the hardware.

8) The backup opportunities are whenever you want them.

9) Depends on flavour and version again.

10) UNIX wins hands down. On NT if I crash a program I often need to reboot the machine but on UNIX the worst I need to do is kill (or ignore) the shell and start up a new one. Usually I can just start up the application in the same shell.

11) As far as I know there is at least one flavour of UNIX which will run on every architecture I have come across.  NT will only run on two families of machines - Intel x86 and Dec Alpha. If you go with NT, stick with DEC in preference to Micro$oft.

If you want a full comparison there must be dozens of documents in the public domain that provide this.  You obviously don't fully understand the significance of the hardware, the operating system, the networking software, etc.  In order to make the decisions or recommendations which you have been tasked with you are going to need a far greater understanding than you will get from Experts Exchange.  Perhaps you should approach the major UNIX and NT vendors and ask them to come up with suitable solutions to your problem. Then you should show their proposals to a real expert or two so that they can point out the errors.

This is not a simple question to answer and I have not done it justice but even 1000 points would not get you all the right answers in Experts Exchange.

Thank you for your answer.
I would like to add two comments to your answer :
1)The first question about the threads - What is the maximum
  number of thread support - in AIX 4.3 and in NT SERVER 4.0
2)The Data Base - is Oracle , Informix and Sybase has a version
  for unix.
Again thank you.
I don't know the maximum number of threads on any system, nor where to find out the information.

Oracle, Informix and Sybase have versions which run on many flavours of UNIX which probably includes AIX 4.3 but you would have to consult them.

Does this satisfy your curiosity for now?
