An unweighted path length measures the number of edges in a graph. Breadth first search traverses the graph in "layers", beginning with the closest nodes to the ending location first. The computer knows about neighbors by checking the graph storage (such as the adjacency matrix or the adjacency list). Breadth first traversals use a stack to process nodes.
