What are the three basic network topologies?

The three basic network topologies are star, bus, and ring. In a star topology, all devices are connected to a central hub or switch, facilitating easy management and troubleshooting. A bus topology connects all devices along a single cable, making it cost-effective but less reliable due to its single point of failure. In a ring topology, each device is connected in a circular fashion, where data travels in one direction, providing predictable data transmission but also presenting challenges if one device fails.
