a switch
A star topology uses a central network device, such as a hub or a switch, to connect all nodes in the network. Each node is connected directly to the central device, creating a centralized architecture that simplifies network management and troubleshooting.

logical channel
If by Star you mean a Star Topology, it is a network cabling scheme in which all nodes are individually connected to a central hub.
Star
star topology
A network star topology has all the clients connect to a central device, such as a hub or switch. The clients look like points of a star, hence the term star topology.

The Public Switched Telephone Network (PSTN) is primarily based on three topologies: the star topology, the ring topology, and the mesh topology. In a star topology, all devices connect to a central hub or switch, facilitating straightforward communication. The ring topology connects devices in a circular fashion, allowing data to pass in one direction, while the mesh topology offers multiple pathways between nodes for redundancy and reliability. Each topology serves distinct purposes in the overall structure of the PSTN.
A network topology in which network nodes are connected in a circular configuration. Each nodes Examines the data sent through the ring and passes on data not addresses to it.this iz ring topology A network layout or design in which each node is connected to a central hub. The hub establishes, maintains and terminates all connections between the nodes. In a LAN, the hub is likely to be a workstation, whereas in larger multi-point networks the hub is more likely to a multiplexer.this is star topology jyoti bhubanesw3ar
Depends on which topology you are used i.e Ring, Bus, Mesh or Star. Like in Ring topology each node is connected to 2 nodes on either side and is suitable for small network. In Star topology there is a central node to which all other nodes are connected, data is transferred from source node to central hub and then to destination node. In Bus topology one long cable act as a back bone to link all the devices and is reliable from hardware point of view.
