Sysdate Value

Hi All

I want to know how exactly 'select sysdate from dual' works. From where Oracle brings in sysdate if the init parameter fixed_date do not have any value set against it. I know it brings the server machine date time and if it does then exactly how is sysdate pointed to bring in server time when Oracle is installed. Is there a script or how does it goes.

Thanks in advance
