Simple Oracle Questions

I know this may seem like a silly question but here goes anyway.

        I have seen many adds in the paper offering jobs to those individuals that know Oracle. I understand that Oracle is a DBMS but what platforms does it run on and where can I get a copy and how much does it cost.

        If my intuition is correct I believe Oracle is a unix DBMS. If so will it run on any version of UNIX?

        I am sorry if this seems quite trivial but I am just trying to get some answers
