The topology with the highest reliability is the Mesh Topology.

Here's why:

1. Ring Topology: In this topology, each device is connected to two other devices, forming a circular network path. If one device fails, it can disrupt the entire network.

2. Bus Topology: In this topology, all devices are connected to a central cable, called the bus. If the central cable fails, the entire network goes down.

3. Star Topology: In this topology, all devices are connected to a central device. If the central device fails, all devices lose connectivity. However, if a non-central device fails, only that device is affected.

4. Mesh Topology: In this topology, each device is connected to every other device. This means that even if one device fails, the network can still function because there are multiple paths between devices. This makes it the most reliable topology.
