ε-NFA, Mealy & Moore Machines | TOC for GATE 2027 | Complete Explanation

Hello everyone 👋

In this video, we continue our **Theory of Computation (TOC)** preparation for **GATE 2027** and cover some very important automata concepts.

📘 Topics covered in this video:
• ε-NFA (Epsilon NFA)
• ε-closure concept
• Difference between NFA and ε-NFA
• Conversion of ε-NFA to NFA / DFA (conceptual)
• Introduction to Finite State Machines
• Mealy Machine:
– Definition
– Output on transitions
• Moore Machine:
– Definition
– Output on states
• Difference between Mealy and Moore Machines
• GATE-oriented understanding and examples

🎯 Why these topics are important for GATE:
• ε-NFA questions test conceptual clarity
• Mealy & Moore Machines are frequently asked in TOC
• Easy scoring if fundamentals are clear
• Often mixed with DFA/NFA questions

This video is part of my **GATE 2027 preparation journey**, where I focus on:
• Concept clarity
• Exam-oriented explanations
• Step-by-step learning
