What do you mean by that? Does it serve up web-pages? Yes.
Is it a multi-threaded windows application? No.

No idea - have you looked at /etc/passwd ?

Are you looking after the server, is it a shared, or private
virtual set-up?



Cheers,

Thank you very much that was indeed very helpful to me.

Regarding my question (Is apache default application server in linux?)
We all know that IIS comes preloaded with Windows Operating system and we dont need to install any extra application server if you need to host pages like (asp,aspx,html so on).
but when it comes to linux server. There is no IIS so it is not possible to host asp,aspx .Therefore most of linux servers include apache as their default application server into their OS. This is what i have observed . M i correct?

I m using Linux server to host Virtual machines (Oracle VM).

Apache is the default webserver for Linux. The processes run under the name httpd ( HyperText Transfer Protocol Daemon) http://en.wikipedia.org/wiki/Hyperte...nsfer_Protocol .
IIS is the equivalent on MS.
Note
1. these are http servers, not 'application' servers. application is a vague term
2. You can also have Apache on MS

See http://httpd.apache.org/ for full docs
