Logical structure of the machine (unchanging) Internal settings (usually changed less frequently than external settings) External settings (usually changed more frequently than internal settings) Discovering the logical structure of the machine may be called "breaking" it, a one-off process except when changes or additions were made to the machines. Finding the internal and external settings for one or more messages may be called "solving" - although breaking is often used for this process as well. The various
