Star

• The star topology is currently used in networks today, and it’s the main topology used to connect edge devices (end users)
• • All network devices are wired back to a hub or switch.
  • The computers can be next to each other or spread out across an office space, but all communication goes back to a central location.
• • 1st benefit: This topology is widely adopted because it concentrates the failure and diagnostic points in a central location.
  • 2nd benefit: we can swap out the edge switches all from the same location
• Disadvantage: if a switch fails, every device connected to the switch is affected.
• Many buildings have multiple star topologies; as an example, the edge switch is wired back to a larger switch, sometimes called a core switch.
