Edge

Edge is a term used across disciplines to denote a boundary or connection. In geometry, an edge is a line segment where two faces meet on a polygon or polyhedron. In graph theory, an edge is a relation between two vertices and may be directed or undirected and weighted.

Edges serve as boundaries in physical objects and landscapes, such as the edges of a polygonal region or a blade. In materials science, edge geometry can affect stress concentration and fracture behavior at boundaries and joints.

In computing, edge refers to edge computing, a model in which data processing occurs near the source rather than in centralized servers. This approach can reduce latency and bandwidth needs but introduces challenges in security, management, and data consistency.

Microsoft Edge is a web browser developed by Microsoft. Rebuilt on the Chromium engine, it supports modern web standards, security features, and extensive extensions. Edge targets multiple platforms, including Windows, macOS, iOS, and Android, and competes with other major browsers.

In everyday language, edge can mean an advantage or a margin at a boundary. It also describes the sharp margin of a blade or the state of being on the cusp of a change or risk, as in "on the edge."
