uh....... what is the question exactly?
Anyway Remoting is .NET specific. Web Services is platform neutral but is
(almost shamefully) easy to write with .NET. DCOM work with .NET no problem.
For Corba there is some port
(http://www.google.com.au/search?hl=en&q=corba+.NET&meta=)
2)No.of threads in a thread pool where N is a process?

you can't multiply a process's HANDLE by a number. doesn't make sense!
anyway each process has its own thread pool. which is limited to 25 thread.
but nothing prevent you to create your own thread with this single line
new Thread(ThreadedMethod).Start()
(Beware most classes are threat UNSAFE by default. (including WinForm))
(here I speak of the framework's ThreadPool class, but nothing prevent you
to write your own, it's quite easy. In fact it's advised if you plan to make
heavy uses of it, has the GUI uses it and could be hampered if no thread is
available)
3)How many generations of objects can exists in GC.?
Is it 1,2,3,4. 2

4)What is Factory /Factory Setting? Is it available in dotnet/VB?

uh?
depend on the factory I suppose......
the only "Standart" factory I know of is for DbConnection in ADO.NET.
Introduce in 2.0.
Otherwise you could do whatever factory you like in your in your code!
Is it Factory,Abstract Factory,Build & Singleton.

Singleton is very common! I don't know about the other! But it's all up to
you man!
 
He wants someone to answer questions on some sort of school test. I wouldn't
help him, it's considered kind of a "no-no" around here.
 
So,
How'd you do on your take-home test?

Hopefully, we didn't spoil your learning by doing any of the hard work for
you.

As for the Factory, Abstract Factory, Builder and Singleton, these are
design patterns.
