TAFL | Unit-4 | Lecture-64 | Introduction to Pushdown Automata | AKTU B.Tech CSE

🎓 Welcome to CS Pathshala!

📘 Lecture 64 – Unit 4 (TAFL)
Introduction to Pushdown Automata (PDA)

In this lecture, we begin Unit 4 with an introduction to Pushdown Automata (PDA), an important computational model used to recognize Context Free Languages (CFLs). PDA extends finite automata by using a stack, making it more powerful.

🔹 In this lecture, we cover:
✅ What is Pushdown Automata (PDA)
✅ Why PDA is needed (limitations of FA)
✅ Basic components of PDA
✅ Role of stack in computation
✅ Real-life intuition and examples

📌 This topic is very important for AKTU exams, GATE, and NET, especially for theoretical and machine-based questions in Automata Theory.

📚 Language: Easy Hindi + English (Concept Based Explanation)
🎯 Helpful for B.Tech CSE students, semester exams, and competitive exam preparation
