In graph theory, a graph shows a set of connections between objects. Each object is a vertex. Each connection, between two vertices, forms an edge, or arc.

A directed edge has a direction associated with it, so it is thought of as coming from one of the vertices and going to the other one. An undirected edge treats both vertices interchangeably. Often, a real number is associated with each edge. These numbers are called weights.

Edge is the nickname of David Howell Evans (the Edge).

Edge is also the stage name of Canadian professional wrestler Adam Copeland.

EDGE is also an acronym for "Enhanced Data Rates for GSM Evolution"

EDGE is a major improvement in GSM technology that allows consumers to use cellular handsets, PC cards, PDAss and other wireless devices to connect to the Internet at data rates up to four times faster than existing GSM and GPRS wireless devices.
