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.
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.
The star topology has the inherent weakness of a single point of failure, as all devices connect to a central hub or switch. If the central device fails, communication between all connected devices is disrupted. Similarly, the bus topology also exhibits this vulnerability; if the main cable (bus) fails at any point, it can halt the entire network's functionality. In both cases, the network's reliability is compromised by dependency on a single component.
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 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.
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 star topology.
Star topology
No, there is not.
A star topology; a network topology in which endpoints on a network are connected to a common central device by point-to-point links.
bus topology
It is called a Star topology
A star topology allows for a single point of failure, as all devices are connected to a central hub or switch. If this central device fails, communication across the entire network is disrupted, while individual devices can still function normally if they are not dependent on the hub. This design simplifies troubleshooting but also creates a vulnerability, as the failure of the hub affects the entire network.
STAR Topology
in star topology , the central hub is called...... (i) active hub (ii) passive hub (iii) inactive hub (iv) live hub
Star topology:- In this topology all PC are connected with the central device. Central may be HUB and SWITCH. Star widely use in all over word. Ring topology:- In this ring topology all PC are connected in the frame of ring are close Ring topology use MSAU each PC has a two never road one is called up Stream and called down stream. It used token passing Matterhorn which implement the token ring network. " Is the best of star topology".
This question is phrased badly, as all networks have a particular type of topology. Briefly, these resolve to 'cloud' (many to many), 'star' (many to a central point) and ring (each node connects to two others, which results in a complete ring). See topic 'Network topology'. The issues to be dealt with are latency, connectivity and fault tolerance.
Such topology is called star.
