HotSpot Default Garbage Collector - Serial Collector

This section describes basic steps of a Tenured Generation Collection, also called a Full Collection, which uses a simple 3-step Mark-Sweep-Compact algorithm on the entire Tenured Generation.

In previous two sections, we learned the 3-area (Eden, Survivor Space "From" and Survivor Space "To") algorithm used in Minor Collection and the 3-step (Mark, Sweep and Compact) algorithm used in the Full collection. When using them together with the 2-generation (Young Generation and Tenured Generation) architecture used in the Heap, we have our first complete garbage collector model, which is referred as the Serial Collector.

What Is Serial Collector? Serial Collector is the default garbage collector used in HotSpot Client version since 1.5. I gathered the following information about Serial Collector from Oracle documentations:
