... the first thing you should do is to open the Concept Guide at For example, in this specific case, "Overview of the System Global Area (SGA)" at In there you also find the term "server processes"... so, if you don't know what those things are, you check the Glossary available in the same book. So, for "server processes", you find a definition at

The Concept Guide is one of the most important books published by Oracle. Every time you have question related to the architecture of the database engine, you should refer to it.
