Question
What are the functions of nodes and paths in a network?
Step 1
They represent discrete components that can connect to other components. In different contexts, nodes might be called vertices, points, or entities. Nodes can represent computers, servers, routers, switches, or any device in a computer network; people in a social Show more…

A graph is a data structure made from nodes and edges. A graph is similar to a tree, but more general, as it may contain cycles. All trees are graphs, but not all graphs are trees. A graph is made of nodes (values) and edges (relationships between values). An undirected graph is a graph where all edges go both ways. Below is an example of an undirected graph: A node is a value in the graph. What are the 4 nodes in this graph? An edge is a relationship between two nodes in the graph. There is an edge connecting A to B. That means there is a relationship between them. We write this edge as (A,B). What are all the edges in this graph? A path is a sequence of nodes that can be used to travel between two nodes. This is written as the sequence of nodes traveled through. We can travel from B to D by the path (B,C,D) or the path (B,D). Give 2 different paths to get from A to D. A cycle is a path that starts and ends at the same point. For example, (A,B,C,A) is a cycle. Give a cycle starting at node D.
