What are the three types of network topology mentioned?

The three types of network topology mentioned as correct in this context include Bus, Ring, and Star topology.

Each of these topologies represents a different method of connecting devices within a network:

1. Bus Topology: In this arrangement, all devices share a single communication line or cable. Data is transmitted in both directions, and devices are connected to the bus using taps. This type of topology is simple and cost-effective for small networks.

2. Ring Topology: In a ring topology, each device is connected to two other devices, forming a circular pathway for signals. Data travels in one direction (or both in some configurations), and each device acts as a repeater to keep the signal strong throughout the network.

3. Star Topology: The star topology features a central hub or switch to which all devices connect. Each device has a dedicated connection to the hub, which makes it easy to manage the network. If one connection fails, it does not affect the rest of the network, making it reliable and easy to troubleshoot.

These topologies are fundamental concepts in networking and are often discussed together because they showcase various ways to structure a network based on different requirements such as scalability, reliability, and ease of installation
