________ is NOT a common network topology.

Question

UnlockIAS · Accepted Answer

Correct — D, Grid. Bus, Star, and Ring are among the classic, commonly taught basic network topologies, each describing a specific layout for connecting nodes — a single shared backbone, a central hub, or a closed loop, respectively. 'Grid' is not counted among the standard basic network topologies (Bus, Star, Ring, Mesh, Tree, Hybrid) in this list, making it the one that is NOT common.

Why the other options are wrong — (a) Bus is a standard, common topology — every node connects to a single shared central cable (the 'bus') — so it is wrongly excluded here.  (b) Star is a standard, common topology — every node connects individually to a central hub/switch — so it is wrongly excluded here.  (c) Ring is a standard, common topology — each node connects to exactly two neighbours, forming a closed loop — so it is wrongly excluded here.

Concept: A network topology describes how devices (nodes) are physically or logically arranged and connected. The commonly taught basic topologies are Bus (single shared backbone cable), Star (central hub with each node individually connected), Ring (closed loop, each node linked to two neighbours), plus Mesh, Tree, and Hybrid. 'Grid' is not part of this standard basic set.
