The term "queue automaton" is not widely recognized as a standard or established concept in the fields of computer science, formal language theory, or automata theory based on available reliable encyclopedic sources.
Accurate information is not confirmed regarding a formal definition, theoretical framework, or academic usage of "queue automaton" as a distinct computational model. It may be a colloquial or informal reference to a theoretical automaton that utilizes a queue data structure—capable of First-In-First-Out (FIFO) operations—to store and manipulate symbols during computation, possibly in contrast to more established models like pushdown automata (which use a stack).
If interpreted contextually, a "queue automaton" could hypothetically refer to a variation of a finite automaton augmented with a queue as auxiliary storage. Such a model would theoretically differ from a Turing machine or a pushdown automaton in its storage mechanism and operational rules. However, no peer-reviewed or authoritative sources confirm the standard use, formal properties, or computational equivalence of such a model.
