Topologies

Topologies

1. Types of topologies

   • Star topology
     • Has a central point, which is usually a switch
     • All individual nodes are attached individually
     • Advantages
       • If one node doesn't work, the others will not be affected
       • New nodes can be added easily
     • Disadvantages
       • If central point breaks, no nodes can work
       • Can be expensive if you need to add lots of nodes
   • Mesh topologies
     • Partial or full mesh
     • All the nodes are connected to eachother
     • Disadvantages
       • Not cost effective
       • Would need lots of maintainance
     • Advantages
       • Data can take multiple routes so if one connection is down, it can get there via other ways
       • data can travel quicker

2. What is a topology

   • The arrangement that nodes are in. The most common topologies are star and mesh topologies
