Machines that use stacks to process data.

Introduces machines with a stack (memory) to recognize context-free languages. Closure Properties:

| Machine | Grammar Type | Language Type | Memory | | :--- | :--- | :--- | :--- | | Finite Automata | Type 3 (Regular) | Regular | None (Finite states) | | Pushdown Automata | Type 2 (CFG) | Context-Free | Stack (LIFO) | | Turing Machine | Type 0 (Unrestricted) | Recursively Enumerable | Infinite Tape |

The Turing Machine is the fundamental model of a universal computer. The book covers: Tape, head, and state controls.

A Pushdown Automaton is essentially a finite automaton augmented with an external . The stack operates on a Last-In, First-Out (LIFO) basis, allowing the machine to remember an arbitrary amount of historical information (such as how many 'A's it has seen before it starts matching them with 'B's). PDAs can accept languages either by reaching a designated final state or by completely emptying their stack. 3. Turing Machines and Unrestricted Languages

Automata Theory and Formal Languages form the backbone of theoretical computer science, shaping how we understand computation, compiler design, and language processing. For students and practitioners in India, An Introduction to Automata Theory and Formal Languages by Adesh K. Pandey is a popular reference, often utilized for its structured approach to complex topics.
