Automaton

An automaton is a mathematical model or device that follows a set of predefined rules to process input and produce output, often used to represent computational processes. It can be thought of as a machine that reads input symbols, transitions between states according to specific rules, and eventually produces an answer or action. Automata are foundational in computer science for designing algorithms, programming languages, and understanding how machines recognize patterns or solve problems systematically. Essentially, they are abstract models that simulate logical behaviors of computers and digital systems.
