Type of MYSQL used in Daily Production Environment

Hi,

I just completed the INSTALLATION of MYSQL (by the help of EE’ s Experts). There are some questions that I need to clarify.

There are 5 types of installation: FULL, Server, Client Only and 2 other types
My questions:  Which types are usually USED in the daily production Environment? (Would you explain a little bit why please?)

Thank you
