What type of topology does Ethernet typically use?

Ethernet typically uses a star topology primarily in modern implementations. This is because the star topology offers several advantages like easier troubleshooting, better performance, and the ability to isolate devices on the network. In a star topology, each device connects independently to a central hub or switch, meaning if one connection fails, it doesn't disrupt the entire network.

Historical Ethernet standards, particularly older ones, utilized a bus topology. In a bus topology, all devices are connected to a single continuous cable, and this method can lead to network collisions and makes troubleshooting more difficult. However, as Ethernet technology has evolved, star topology has become more prevalent, particularly in local area networks (LANs), due to its scalability and reliability.

While mesh and ring topologies are utilized in certain network configurations and offer their respective benefits, they are not typical for Ethernet networks. Mesh topologies connect every device to every other device, which can be complex and costly. Similarly, ring topologies connect devices in a circular fashion, which is less common in today's Ethernet implementations. Therefore, recognizing that star topology is the most relevant for modern Ethernet setups helps understand current networking practices.
