Oracle 8i and 9i are different versions of the database. Oracle9i is a newer release to Oracle8i, it will have more enhancements, fixes etc. New features are available to both developers and administrators.

With Oracle each new version contains the same functionality as the previous version. So Oracle 9i is backwards compatible with 8i. Oracle 9i does many things differently internally so they are not exactly the same database engine. And Oracle 9i has a host of new features designed to make the database more stable, easier to manage and increase functionality. There are so many new features that Oracle Corp. provides a complete manual listing these new feature. The Oracle 9i New Features manual can be found on Oracle's Technet site at if you are interested. You will need to register for a free account if you want to view documentation on that site.

Your Question is very theoritical and is out of scope of this forum to answer. You can go through some good oracle book or google out some materials for theoritical questions.
