When i am going through some code in my project, i found something term called $SIG{HUP},$SIG{TERM}. Can anybody give me some idea about these signals..
Well, here it's clear you have to do with a hash called %SIG. Check perldoc perlvar: 
%SIG
$SIG{expr}
        The hash %SIG contains signal handlers for signals.  For exam-
        ple:

and read the docs referenced therein, e.g. perldoc perlipc.
and also what are the various signals that are present in perl. I am using perl version 5.00_03.
Signals are not stuff "present in perl". They rather have to do with the OS, although (from the same source as above): 
        Certain internal hooks can be also set using the %SIG hash.

In any case if you're really interested, you may benefit from reading a UNIX programming book, even if not a Perl one.
