Interactive Mode (Default): Available for hdblcm or hdblcmgui. The person installing the system must enter parameter specifications iteratively until the installation process finishes.
Batch Mode: Available for hdblcm. The installation accepts the default values for all unspecified parameters, and runs to completion without any additional input required.

If there are multiple hosts in a system, it is called a multiple-host (or distributed) system.
A multiple-host system is a system with more than one host.
