topology

1. General: Study of physical space which, unlike geometry, is not concerned with exact dimensions and angles but with those properties of a surface that remain unaffected by distortion such as contiguity, order, and relative position.

2. Networking: Map of the wiring scheme of a network. It depicts where computers and devices (nodes) such as bridges, gateways, routers are located and how they are interconnected. Networks are usually configured in bus, ring, or star topologies or their hybrids.
