I believe that this link will help with most of your questions.
http://www.postgresql.org/about/

But to over simplify my answer to your question, PostgreSQL is like/similar to:

Oracle RDMS,
MS SQL server RDMS,
DB2 RDMS,
MySQL,
et. al.

All of your questions can be answered in the PostgreSQL manual.

If you want to know what kinds of things PostgreSQL can do I would search for link about "RDMS."
This link any many like it will explain.
http://en.wikipedia.org/wiki/RDBMS

Postgresql can be configured to work and an server to external client if you configure it that
way. Or It can be configured to only accept interal client in the server.
