Network Topology

What is network topology

what is network topology?

Network topology is the arrangement of the various elements (links, nodes, etc.) of a computer network. Essentially, it is the topological structure of a network and may be depicted physically or logically.

Examples of topology

  1. Star Topology
  2. Ring Topology
  3. Bus Topology
  4. Tree Topology
  5. Mesh Topology
  6. Hybrid Topology

advantages of star

Advantages of a Star Topology

  1. Easy to install and wire.
  2. No disruptions to the network then connecting or removing devices.
  3. Easy to detect faults and to remove parts.

disadvantages of star

Disadvantages of a Star Topology

  1. Requires more cable length than a linear topology.
  2. If the hub or concentrator fails, nodes attached are disabled.
  3. More expensive than linear bus topologies because of the cost of the concentrators.

The protocols used with star configurations are usually Ethernet or LocalTalk. Token Ring uses a similar topology, called the star-wired ring.
