What will happen to star network if the hub fails?
if a hub or switch fails, all the devices connected to it will have no network connection.
Which is the central device for star network?
Explanation: Hub/switch is the central device in star topology.
What is the central node of a star network?
Star topology is a network topology in which each network component is physically connected to a central node such as a router, hub or switch. In a star topology, the central hub acts like a server and the connecting nodes act like clients.
What will happen if a computer or device on a ring network fails?
Because a ring topology provides only one pathway between any two nodes, ring networks may be disrupted by the failure of a single link. A node failure or cable break might isolate every node attached to the ring. Very orderly network where every device has access to the token and the opportunity to transmit.
What is the effect of failure of a cable in star network?
If one cable breaks or fails, only the computer that is connected to that cable is unable to use the network. A star topology is scalable. As the network grows or changes, computers are simply added or removed from the central connection point, which is usually a hub or a switch.
What happens when a link failure occurs in a star topology?
What happens when a link failure occurs in a star topology? If the router should malfunction for any reason, communication among computers in the network will be cut off.
What is the advantage and disadvantage of star topology?
Comparison Table for Advantages & Disadvantages of Star Topology
| Advantages | Disadvantages |
|---|---|
| High speed | High maintenance |
| Highly scalable network | High dependency on the central device |
| Highly efficient | Expensive |
| Centralized network management | Requires additional equipment |
What happens if a host goes down in star topology?
What happens if a host goes down in a star topology? The downed host will not have a connection to the central hub, but all other devices can connect. The data will instead work downstream up to the break.
What is the advantage and disadvantage of ring topology?
Most ring topologies allow packets to travel only in one direction, called a unidirectional ring network. Others permit data to move in either direction, called bidirectional. The major disadvantage of a ring topology is that if any individual connection in the ring is broken, the entire network is affected.
What are the disadvantages of a ring network?
Disadvantages of Ring topology :
- Due to the Uni-directional Ring, a data packet (token) must have to pass through all the nodes.
- If one workstation shuts down, it affects whole network or if a node goes down entire network goes down.
- It is slower in performance as compared to the bus topology.
- It is Expensive.
What is the single point of failure for a star topology?
The star topology is the most widely implemented network design in use today, but it is not without its shortcomings. Because all devices connect to a centralized hub, this creates a single point of failure for the network. If the hub fails, any device connected to it will not be able to access the network.
What are the advantages and disadvantages of a star network?
Advantages and disadvantages of a star network The advantages of a star network are: it is very reliable – if one cable or device fails then all the others will continue to work it is high-performing as no data collisions can occur
How are devices connected to a star network?
The star network In a star network each device on the network has its own cable that connects to a switch or hub. A hub sends every packet of data to every device, whereas a switch only sends a packet of data to the destination device. A star network, where devices are connected to a central hub or switch
Why do we use star topology in a network?
The host computer acts as a repeater for data flow. In star topology, fewer cables are needed because each device only needs to be connected to a host computer or hub. It is simple to troubleshoot. If one device is a failed, so only that device is affected, and All remain devices active.
How is a star network different from a bus network?
Answer: B. Each node on a star network uses its own cable, making it easy to add users without disrupting current users. Adding a node to a bus network will involve breaking the segment, which makes it inaccessible to all other nodes on the network. A ring network topology will require that the ring be broken to add a new device.
