Chapter 7

• Mark and sweep
• CMS garbage collection
• Serial garbage collection
• Parallel garbage collection

2. The G1 name refers to Garbage First.

3. iCMS (short for Incremental Concurrent Mark Sweep) mode is intended for servers with a small number of CPUs. It should not be employed on modern hardware.

4. MiB stands for Mebibyte, which is a multiple of bytes for digital information.
