What type of network uses multiple pathways for data transmission to increase reliability?

A mesh network is a type of network that employs multiple pathways for data transmission. This architecture is designed to enhance reliability by allowing data to be rerouted through alternative paths in the event of a failure or blockage in one pathway. In a mesh network, each device is connected to several other devices, which creates a network where each node can communicate directly with multiple other nodes. This redundancy significantly increases the chances of data being successfully transmitted, even if some connections are disrupted.

This design contrasts with other network types. For instance, a star network relies on a central hub; if that hub fails, the entire network can go down. A ring network organizes devices in a circular path; if one connection fails, it can disrupt the entire network unless there are specific protocols in place. A bus network uses a single central cable to connect all devices, which means that if that cable fails, communication across the entire network ceases. Thus, the mesh network's robust architecture and redundancy make it an optimal choice for ensuring reliability in data transmission.
