Hai 
Data in this segment is initialised to zero or made null(applicable to 
pointers) before the program starts executing.This is different from 
the explicit initialisation of data by user.
Essentially you need this segment to hold the variables which are 
declared outside any function.
the C declaration outside any function like
long mySum;
will fall in to uninitialised data segment.
