Step 1: Understand what BFS stands for. BFS means Breadth-First Search, which is a way to explore graphs.
Step 2: Know what a graph is. A graph is made up of nodes (or vertices) and edges (connections between nodes).
Step 3: Learn about unweighted graphs. An unweighted graph means that all edges are treated equally, with no specific cost or weight.
Step 4: Identify what connected components are. Connected components are groups of nodes in a graph where there is a path between any two nodes in the same group.
Step 5: Realize how BFS helps. BFS starts at a node and explores all its neighbors before moving to the next level of neighbors, which helps in finding all nodes connected to the starting node.
Step 6: Conclude that BFS can be used to find all connected components by starting BFS from each unvisited node until all nodes are visited.
