What Device Is Used to Create a Physical Star Topology?

Answer:

A switch or a hub is used to create a physical star topology.

Star topology:

A star topology is the local area network topology (LAN) in which all the devices, workstations, and modes of PCs are directly connected to the hub also referred to as the central computer. Therefore, star topology is also referred to as star network and network topology The hub is used as an intermediary device where each workstation is connected to the hub and indirectly connected to other workstations through a hub or switch. It is installed at the access layer of the enterprise networks. Centralized network switches or hubs are used by the access layer to connect to all endpoints of the local area network.

It needs a point-to-point connection between the connecting devices and the central hub, node, or switches. For the improvements in the communication between the devices on the network, the amplification and reconditioning service are provided by the central nodes. Star topology is mostly used in home networks.

Features of star topology:

• Star topology is adaptable.
• On the central connection point, all cables are run on it.
• If one node breaks down only the computer connected to that cable stop working others are not affected.
• For maintaining and expanding the network cost will increase because many cables are used to connect individual devices to the central point.
• Computers are added or removed from the central nodes when the network changes occurred.

Advantages of star topology:

• In star network topology every node is independent of other nodes. If one node is not working properly it will not affect the performance of other nodes of the network. It limits the single-point failure impact on other nodes of the network.
• It provides a facility to add and remove additional components to the network based on the conditions. This network is mostly small to avoid competition between the devices for accessing the central node or hubs.
