This lecture explains Breadth First Search (BFS), one of the most important graph traversal algorithms in Data Structures and a highly scoring topic in university exams.

BFS explores a graph level by level using a Queue, and it is widely used in shortest path problems, connectivity checking, and networking applications.

✅ You Will Learn (Exam-Oriented):

What is Breadth First Search (BFS)
Why BFS is called level order traversal of graph
Role of Queue in BFS
BFS algorithm (step-by-step)
BFS traversal using Adjacency Matrix
BFS traversal using Adjacency List
Example-based BFS traversal
Time complexity: O(V + E)
Applications of BFS
How BFS questions are asked in exams

The explanation is algorithmic, example-driven, and strictly exam-focused, ideal for 5–10 mark questions and viva.
