Zorluk: ZorNetwork Topologies and Types

An industrial facility operates a legacy control network where every client automation terminal connects via an individual twisted-pair cable directly to a central multiport Ethernet switch. However, the media access control protocol running across the network relies on a token-passing scheme, where frame transmission rights are passed sequentially from workstation to workstation in a continuous deterministic cycle. Which option correctly identifies both the physical and logical topologies of this network architecture?

  4. D
    Physical Ring topology and Logical Bus topology

Cevap

Physical Star topology and Logical Ring topology
Physical topology refers to the actual arrangement of physical cabling and central connecting devices (in this case, individual cables running from endpoints to a central switch forming a star). Logical topology refers to the path data takes across the network (in this case, token passing sequentially from node to node in a logical circle). Therefore, the deployment is a Physical Star, Logical Ring topology.

Adım Adım Çözüm

1
Analyze the physical layout description.
Individual point-to-point cables running from each endpoint directly into a central multiport switch define a Physical Star layout.
Physical topology represents the actual physical cabling and hardware layout of the network infrastructure.
2
Analyze the data transmission mechanism.
Sequentially passing token rights from node to node in a deterministic cycle defines a Logical Ring topology.
Logical topology describes how data actually travels across the network protocol stack regardless of the underlying physical cable routes.
3
Synthesize the physical and logical characteristics.
The infrastructure combines a Physical Star with a Logical Ring.
Matching both physical cabling patterns and logical frame flow paths confirms the hybrid topology classification.
