| BFS STANDS for Breadth First Search. | DFS stands for Depth First Search. |
| BFS(Breadth First Search) employs the Queue data structure to determine the shortest path. | DFS(Depth First Search) employs the Stack data structure. |
| Because BFS reaches a vertex with the fewest number of EDGES from a source vertex, it can be used to identify a single source shortest path in an unweighted graph. | To get from a source vertex to a DESTINATION vertex in DFS, we may have to traverse through additional edges. |
| BFS is better at finding vertices that are CLOSE to the specified source. | When there are solutions that are not close to the source, DFS is a better option. |
| BFS has a time complexity of O(V + E) when using an Adjacency List and O(V^2) when using an Adjacency Matrix, where V stands for vertices and E stands for edges. | DFS also has a time complexity of O(V + E) when using an Adjacency List and O(V2) when using an Adjacency Matrix, where V stands for vertices and E stands for edges. |
| Here, the siblings of a node are visited before visiting the children. | Here, children of a node are visited before visiting the siblings. |
