Myhill-Nerode Theorem (for Regular Languages):
The Myhill-Nerode Theorem provides a method to determine whether a language is regular and helps in minimizing finite automata.
A Pushdown Automaton (PDA) is a type of computational model used to recognize context-free languages. It is more powerful than a finite automaton because it uses an additional memory structure called a stack.
A Turing Machine (TM) is a theoretical computational model invented by Alan Turing in 1936. It is one of the most powerful models of computation and serves as the foundation of modern computer science.
