Modeless:    A modeless component is a component whose functional operations can be meaningfully invoked in any sequence at any time. For example, many order-entry systems require that an order header is entered before any order line. This business rule is ingrained into the system: It is not possible, say, to enter an order line before creating the order header. In modeless order entry, order details can be entered in any sequence, so that an order line could be created whether or not the order header has been created.

Module:    A physical file that is loadable into the run-time and capable of being executed. That is, a module consists of compiled and linked code (when written in a language that must be compiled and linked before being executed). An example of a module is a Windows DLL or EXE file.
