What are the advantages and disadvantages of star topology over bus topology?

What are the advantages and disadvantages of star topology over bus topology?

Star Topology

  • Easy to install and wire.
  • No disruptions to the network when connecting or removing devices.
  • Requires more cable length than a linear bus topology.
  • If the connecting network device (network switch) fails, nodes attached are disabled and cannot participate in computer network communication.

What is star topology Slideshare?

Star Topology consists of a central Node in which all other nodes are connected. This Central Node provides a Common Connection Point for all nodes through a Hub. In this topology, every node(Computer, Workstation or any other Peripheral) is connected to a central node called a Hub or Switch .

What is network topology PPT?

1. Network topology. Topology • Topology refers to the layout of connected devices on a network.

What are some advantages of a star topology?

Advantages of Star Topology

  • It is very reliable – if one cable or device fails then all the others will still work.
  • It is high-performing as no data collisions can occur.
  • Less expensive because each device only need one I/O port and wishes to be connected with hub with one link.
  • Easier to put in.
  • Robust in nature.

What are the disadvantages of topology?

Disadvantages of Ring Topology

  • The failure of a single node in the network can cause the entire network to fail.
  • The movement or changes made to network nodes affect the entire network’s performance.
  • Data sent from one node to another has to pass through all the intermediate nodes.

What is the advantages of star topology over bus topology?

Star topology has a high implementation cost because of the central hub and extra wires required for connection. Bus topology is less expensive than a star topology. 6. Data transmission is faster in a star topology.

What are the features of star topology?

The Star Topology (Hierarchical) Characteristics of a star topology are as follows: All cables run to a central connection point. 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.

What is the conclusion of star topology?

Star Topology Conclusion A Star Network Topology is best suited for smaller networks and works efficiently when there is limited number of nodes. One has to ensure that the hub or the central node is always working and extra security features should be added to the hub because it s the heart of the network.

What is star in networking?

A star network is an implementation of a spoke–hub distribution paradigm in computer networks. In a star network, every host is connected to a central hub. In its simplest form, one central hub acts as a conduit to transmit messages. The star network is one of the most common computer network topologies.

What is the disadvantage of star topology Mcq?

Disadvantages of Star Topology Network operation depends on the functioning of the central hub. Hence, central hub failure leads to failure of the entire network. Also, the number of nodes that can be added, depends on the capacity of the central hub. The setup cost is quite high.

What are the benefits of star topology?

Star topology features a better fault tolerance. When a star topology experiences a cut cable or a NIC failure,then it will only affect one node.

  • You can extend the reach of the network by creating multiple stars. Star topology has natural limitations that come into play when setting up the network.
  • Star topology systems are highly scalable.
  • What are advantages of star topology over ring topology?

    Requires more cable than a linear bus .

  • If the connecting network device (network switch) fails,nodes attached are disabled and can’t participate in network communication.
  • More expensive than linear bus topology due to the value of the connecting devices (network switches)
  • What are differences between star and mesh network topologies?

    Devices or nodes can not move freely.

  • In Ad hoc mode,devices are autonomous and free to move.
  • In Infrastructure mode,movement of nodes are restricted around the control center.
  • Is star topology faster then mesh topology?

    In star topology devices are connected to the center switch or hub and all interconnection between them are done through that center hub. But in mesh topology each devices are connected to other devices directly by individual cables without using center hub. Theoretically the fastest topology should be mesh topology.
