Infotron: An information device, or an infotron, is a black box that can capture, process, store, transmit, transduce and/or display information.
Message: A message is a discrete bundle of information passed from one infotron to another
Channel: A channel is a definite, directed path between two infotrons along which messages travel.
Blueprint: A blueprint is a specification or a set of specifications that can be passed to a constructor.
Constructor: A constructor is an infotron capable of producing the specified running instances of infotrons described by a blueprint.
Domain: A domain is an encapsulation of one or more infotrons capable of having channels established with any other. A domain is, itself, considered an infotron.
Terminal: A terminal is an infotron that belong to more than one domain. They serve as the input and output ports for infotrons through which messages flow.
Star: Star is a platform-specific runtime kernel that provides the scheduling of infotron execution and facilitates asynchronous message passing among infotrons. It may also provide various types of management facilities such as memory allocation, bootstrapping, and channel establishment.
