, which ranked the power of various "Automata"—machines designed to recognize these languages: The Finite Automata (DFA/NFA): These were the simplest soldiers, perfect for recognizing Regular Languages and managing things like traffic signals or text searches. The Pushdown Automata (PDA): These machines had "memory" (a stack) and could handle Context-Free Languages
