What is a 'mesh network'?

A mesh network is defined as a type of network where each node relays data for the network, meaning that each device or node can communicate with one another directly or indirectly. This design allows for greater redundancy and reliability since if one particular node fails, the data can still reach its destination through alternative pathways. Mesh networks are particularly effective in scenarios where a robust and resilient communication method is needed, such as in wireless technologies, where devices can communicate with each other without relying on a central point of failure.

In contrast, the other descriptions do not accurately depict mesh networks. A network that connects all computers to a central hub describes a star topology, where devices depend on the hub for communication. A type of network that requires multiple routers may refer to more complex networking scenarios but does not capture the essence of how a mesh operates. Finally, a network that uses fiber optic cables exclusively refers to a specific medium of data transmission rather than the structural arrangement of the network itself.
