Which topology is characterized by a central hub and the ability for easy addition of devices?

The star topology is characterized by having a central hub or switch to which all devices (nodes) are connected. This structure allows for easy addition of new devices without disrupting the network. When a new device needs to be added, it can simply be connected to the hub, and the network remains intact for the other devices already in use. This ease of scalability, along with the centralized control provided by the hub, makes the star topology a popular choice for many network designs.

In a ring topology, each device is connected to exactly two other devices, forming a loop. This configuration can complicate the addition of new devices, as each device must be individually connected in a sequential manner, and adding a new device could disrupt the existing network.

The bus topology uses a single central cable (the bus) to connect all devices. While it is also relatively simple to set up, adding devices can be more challenging, as it requires additional cabling, and any disruptions to the bus can affect all devices connected to it.

The mesh topology provides high redundancy and reliability through multiple direct connections between devices. However, this complexity can make the addition of devices cumbersome and more expensive due to the need for multiple connections and additional cabling.

Overall, the star topology stands
