Which of the following is one of the three most common network topologies?

The star topology is recognized as one of the three most common network topologies due to its structure and efficiency in various networking environments. In a star topology, all network devices are connected to a central hub or switch. This design simplifies the management of the network, as any device can easily be added or removed without affecting the overall network. It also enhances fault tolerance; if one connection fails, it does not disrupt the entire network, allowing other devices to continue functioning normally.

This topology is widely used in both home and business networks because it offers straightforward troubleshooting and ease of installation. While the mesh topology, which allows multiple paths between devices, and the hybrid topology, which combines elements of various topologies, are also common, the star topology stands out for its simplicity and reliability in managing connections. The square topology, however, is not recognized as a standard type and does not hold the same significance or application in networking as the other three.
