Adjacency

⭐⭐⭐⭐
feminine noun (geometry / computer science / topology)

Definition

The state or property of two geometric elements, mathematical structures, or spatial entities of being adjacent, meaning neighboring, contiguous, or directly connected by a common boundary or edge. In graph theory within computer science, this structural phenomenon designates the direct link between two nodes joined by a single edge, serving as the computational basis for network traversal and storage algorithms.
