Which one of the following is not a Network Topology?

This question was previously asked in
UGC NET 2018 Paper 1 Question Paper (8-Jul-2018)
The correct answer is

Chain

To determine which of the given options is not a network topology, let's first understand the concept of network topologies.

Network Topologies: A network topology refers to the arrangement of different elements (links, nodes, etc.) in a computer network. The common network topologies include:

  • Bus Topology: In a bus topology, all computers and devices are connected to a single central cable, or bus.
  • Ring Topology: In a ring topology, each computer is connected to two other computers, forming a circular data path.
  • Star Topology: In a star topology, all computers and devices are connected to a central device (hub or switch).

Now, let's review the provided options:

  1. Bus: As described, this is a recognized network topology where all devices are connected to a central cable.
  2. Chain: There is no such recognized network topology as "Chain." Network topologies typically refer to the arrangement configurations described above.
  3. Ring: This is a recognized topology where devices form a closed loop.
  4. Star: This is a recognized topology where devices connect to a central hub.

Conclusion: The correct answer is Chain as it is not a recognized network topology. The other options (Bus, Ring, Star) are well-known network topologies.
