________ is NOT a common network topology.
- (a)Bus
- (b)Star
- (c)Ring
- (d)Grid
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.
- (a)Bus — 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 — Star is a standard, common topology — every node connects individually to a central hub/switch — so it is wrongly excluded here.
- (c)Ring — Ring is a standard, common topology — each node connects to exactly two neighbours, forming a closed loop — so it is wrongly excluded here.
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.
This is another odd-one-out format — three genuine textbook topology names plus one term ('Grid') that does not belong to the standard basic-topology list taught for networking exams.
- Bus: all nodes share a single central cable/backbone
- Star: all nodes connect individually to a central hub/switch
- Ring: nodes form a closed loop, each linked to two neighbours
- Standard basic topologies: Bus, Star, Ring, Mesh, Tree, Hybrid — 'Grid' is not one of them
Bus, Star, and Ring are standard topologies; Grid is not.
- Assuming any plausible-sounding networking word (like 'Grid') must be a real topology
- Confusing 'Mesh' (a real topology, every node connects to every other) with 'Grid' (not a standard basic topology term)
MPPSC computer-awareness reliably tests the 'NOT a common X' odd-one-out format across networking, security, and hardware terms — memorise the exact standard list so a lookalike term doesn't pass.

In which network topology does every node connect to a central hub or switch?
- (a)Bus
- (b)Ring
- (c)Star
- (d)Mesh
Answer(c) Star — each node has its own link to a central hub/switch.
- practice — not a real PYQ
Which network topology connects every node directly to every other node?
- (a)Bus
- (b)Star
- (c)Ring
- (d)Mesh
Answer(d) Mesh — full or partial direct interconnection between nodes, unlike Bus/Star/Ring.
