Multisite can also mean different domains pointing to the same Drupal 
installation only using different modules, themes, and files but otherwise 
sharing the exact same codebase/database. For example:

technology.example.com
news.example.com
kids.example.com

Multisite doesn't have to just mean completely separate domains/sites. 
Completely separate domains/sites probably would indeed want their own databases.

Settings.php has quite a bit of documentation about multisite installs.
