Network Topologies

Network Topologies

1. A network topology is the form in which data travels around the ring in one direction and each device acts as a repeatear.

2. 4 example of network topologies

   • Bus topology In this topology, all computers connect through a single continuous coaxial cable
   • Ring topology In this topology, all computers connect in a circle
   • Star topologie In this topology, all computers connect to a centralized networking device. Usually, a networking switch or a Hub (in earlier days) is used as the centralized device. Each computer in the network uses its own separate twisted pair cable to connect to the switch.
   • This topology is a mix of two Hybrid Topologie.more topologies

3. advantages of star topology

   • It is very reliable
   • It is high performing as no data collisions can occur
   • Less expensive
   • Robust in nature

4. Disadvantages of star topology

   • Requires more cables than a linear bus
   • If the connecting network device fails, nodes attached are disabled
   • More expensive than bus topology due to the amount of connecting devices

5. Advantages of mesh topology

   • Failure during a single device won't break the network
   • Fault identification is straight forward
   • It provides high privacy and security

6. Disadvantages of Mesh Topology

   • Its costly compared to other topologies
   • Installation is difficult
   • Complex process
