Yes to all.  Most Linux distributions come with Perl.  On Windows, I use ActivePerl http://www.activestate.com/activeperl which has versions for many OS's.  The "Community Edition" is free.

If you install Activeperl on windows 7, then will you be able to write a script that can be understood by Linux and windows? Or you will have to write 2 different scripts ?

Yes, if you do not use any windows 7 specific or Linux specific features.

I have been able to use my few Perl scripts on both Windows and Linux.  However... the Perl repository, CPAN, has over 25,000 modules available so you need to use some care in how your write your Perl scripts.  In addition, you sometimes have to change the line at the top that tells Linux/Unix where to find the Perl interpreter because not all distributions do that the same.  So the answer is that they can be 'mostly' the same.

Most scripts will work equally well on Linux and Windows without changes.  The biggest hurdle I've run into is anything that depends on IO::Tty will not work on Windows (a lesser hurdle is anything in the Win32 namespace won't work on *nix).

-is it used in Web Application Development ?

Perl can satisfy all requirement, but you need to provide a scope of the above as there might be a better alternative.
