In a star topology, there is a central controller or hub. This hub acts as a central point for all network devices, allowing them to communicate with each other through it. If one device fails, it does not affect the others, making troubleshooting easier. However, if the central hub fails, the entire network goes down.

What physical network topology has the inherent weakness of a single point of failure?
The physical network topology that has the inherent weakness of a single point of failure is the star topology. In a star topology, all devices are connected to a central hub or switch. If this central device fails, the entire network becomes inoperable, as all communication relies on it. This makes the network vulnerable to disruptions if the hub experiences any issues.
What physical topology operates around a central network device for networks?
The physical topology that operates around a central network device is known as a star topology. In this configuration, all network devices are connected to a central hub, switch, or router, which facilitates communication between them. This design enhances reliability, as the failure of one connection does not affect the entire network, though the central device's failure can lead to network disruption. Star topology is commonly used in home and office networks due to its simplicity and ease of management.
Which network topology is complete disrupted when a key central device stops operating?
A star topology is completely disrupted when a key central device, typically a hub or switch, stops operating. In this configuration, all devices are connected to the central device, and its failure means that communication between all connected devices is halted. Without this central point, the network becomes inoperative, preventing data transmission.
What three topologies is the PSTN based on?
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.
What is the 3 most used wide area network topology?
The three most commonly used wide area network (WAN) topologies are point-to-point, hub-and-spoke, and mesh. In a point-to-point topology, a direct connection is established between two locations, providing a simple and efficient link. The hub-and-spoke model connects multiple remote sites to a central hub, facilitating easier management and data flow. Mesh topology involves interconnecting multiple nodes directly, allowing for redundancy and resilience, as each node can communicate with multiple others.
Which topology requires a central controller or hub?
Star topology
The topology that uses a central hub is?
A star topology.
What is central hub called in star topology?
in star topology , the central hub is called...... (i) active hub (ii) passive hub (iii) inactive hub (iv) live hub
In topology there is a central controller or hum?
No, there is not.
What type of device is usually found at the center of an extended star topology?
both hubs and switch can act as a center of a star topology
Is star topology the faster of all topology?
No, because there is a hub between star topology and every station connect to that central hub. hub cause broadcast and congession since packet loss is more likely to occur. I suggest that mesh topology is more faster as there is a dedicated link to each node.
What physical network topology has the inherent weakness of a single point of failure?
The physical network topology that has the inherent weakness of a single point of failure is the star topology. In a star topology, all devices are connected to a central hub or switch. If this central device fails, the entire network becomes inoperable, as all communication relies on it. This makes the network vulnerable to disruptions if the hub experiences any issues.
In ring topology what is each node attached to?
For a ring topology each client device is usually attached to a central hub, which is a managed hub, called an MAU or MSAU unit. It contains a grid that manages the electrical portion of the ring.
How to make construction of Star Topology?
To construct a star topology, begin by placing a central hub or switch at the center of the network. Connect all network devices, such as computers and printers, to this central hub using individual cables. Ensure that each device has a dedicated point-to-point connection to the hub, which allows for easy management and troubleshooting. Finally, configure the network settings on each device to facilitate communication through the central hub.
What is Ring topology and Star topology?
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
Which topology has all its nodes connected directly to one center point and has no other connections between nodes?
The topology you are describing is known as a star topology. In this configuration, all nodes are directly connected to a central hub or switch, which serves as the main point of communication. There are no direct connections between the nodes themselves, meaning any data transmitted must pass through the central hub. This design simplifies troubleshooting and management, but if the central hub fails, the entire network goes down.
How does star topology connect to other topology by switch hub and router how does star topology connect with other topology with such router and hubs?
In a star topology, all devices are connected to a central hub or switch, which manages data traffic between them. When integrating with other topologies, such as bus or ring, a router can be used to connect different network segments, allowing communication across diverse network structures. The central hub or switch facilitates easy management and troubleshooting, while the router enables data routing between multiple topologies, ensuring seamless connectivity. This setup enhances network flexibility and scalability.
