Topology Description

Star topology is the most common network configuration where all devices connect to a central hub or switch. Each device has its own dedicated connection to the central node, making it easy to add or remove devices without affecting the rest of the network. This topology is widely used in modern Ethernet networks.

Advantages

  • Easy to install and configure
  • Failure of one node doesn't affect others
  • Easy to troubleshoot and maintain
  • Centralized management
  • Scalable - easy to add new devices

Disadvantages

  • Single point of failure (central hub)
  • Requires more cabling than bus topology
  • Performance depends on central hub
  • Higher cost due to hub/switch
  • If hub fails, entire network goes down
