In a star topology, if the central device (typically a switch or hub) fails, all connected devices lose communication with each other, as the central device acts as the main point of connectivity. However, individual devices can still function independently; they just cannot communicate with others on the network. This makes the system vulnerable to a single point of failure, but the star topology is beneficial for easy troubleshooting and isolation of devices. Replacing or repairing the central device restores network functionality.

Which topology uses a central device for point-to-point connections to other devices?
A star topology; a network topology in which endpoints on a network are connected to a common central device by point-to-point links.
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
Which type of network topology has a central connection device which each computer on the network is connected to?
STAR Topology
What are the characteristics of the star topology?
In a star topology, each device connects to a central network connectivity device such as a hub, switch, or router. These devices would be connected as a "star" (points on a star). The other characteristic of a star topology is that a failing connection will only affect the failed device unless that device is the connectivity device. This means that in most cases a failing device on a star will not take down the entire network. Another characteristic of a star is that they are easily expandable and scalable.
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.
Explain star connection?
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 topology that uses a central hub is?
A star topology.
How star topology works?
In a star topology, all devices are connected directly to a central hub or switch. This central device manages the flow of data between all connected devices, minimizing network collisions and enabling easy addition or removal of devices without affecting the network as a whole. However, if the central hub fails, the whole network can be affected.
Deine the topology and explain the advantage and disadantage of bus star and ring topology?
Topology is the structure that describes how devices in a Network are connected.Bus Topology: Directly connects all devices to network i.e utilises a single Physical medium for Data transmission between devices.Star Topology: Connects all devices in network through a Central Network connecting device such as Hubs & Switches.Advantage of Bus Topology is that less connecting cable is used.Advantage of Star Topology is that Network can function in case one or more devices fail.Disadvantage of Bus Topology is that whole Network goes down if one device fails.Disadvantage of Star Topology is that it requires physical connecting medium from Central device to the connecting device i.e more expensive.
What a star topology uses a to connect all of the nodes?
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.
Which topology requires a central controller or hub?
Star topology
Why is the star topology the best topology?
Scalability and reliabillty of star topology makes it the best, easy to remove or add a device.
