What does "edge" mean in programming?
edge is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
A connection between two vertices in a graph. Edges can be directed (one-way) or undirected (two-way), and can carry a weight (cost). In a road map graph, an edge represents a road between two cities.
Example
"The graph has an edge from node A to node B with weight 5 — meaning traveling A to B costs 5."
