Summary
Swap space is used to increase the apparent size of memory by using disk space. A swap partition is created when the system is installed. If more swap space is needed, swap files can be created and added into the system configuration.
Core files are copies of memory being used by programs that malfunction. These are used to debug software. Core file management involves enabling/disabling core files globally or on a per-process basis along with selecting a directory and naming conventions for core files.
Crash dumps are the core files for the operating system. When the system boots, the crash dump can be saved in a user-accessible area so that it can be analyzed.
