Network – Topologies

This week we back again with the term ‘network topology’. First let’s go over the definition; Network is define as a group of two or more computer units that linked together and topology is define as the symmetrical arrangement of a computer units. There are three main types of network topologies: Centralized, decentralized, and distributed.

Centralized or Star-shaped network topology has two or more devices [node] linked to the center computer [hub]. All devices are communication in the network by passing data through the center computer.

Advantage:

  • A broken device in the network does not affect the rest.
  • Easy to add new devices [node]
  • Fast and effective

Disadvantage:

  • If the hub crashing, the network stop

Decentralized or tree topology, this is a combines of star topologies within star topology.

Advantage:

  • Good for large network as it is allow easily manageable

Disadvantage:

  • Again, If the hub collapsing, the network stop

Distributed or partial mesh topology, some node can be connecting to all other nodes and some are only connect to one, two, or more nodes. (No structure)

Advantage:

  • If some part of the network fails, there are alternative present
  • Good for high traffic activities

Disadvantage:

  • Slow data processing
  • Very hard to manage
