Mesh topology is a network design where each device connects to multiple other devices, ensuring high reliability.

Elaboration:

• Can be full mesh (all devices interconnect) or partial mesh (some devices interconnect).
• Highly fault-tolerant: If one connection fails, data is rerouted through other paths.
• Used in highly secure and resilient networks, such as military and financial institutions.

Example:

A wireless mesh network (WMN) in smart cities, where multiple Wi-Fi routers interconnect for seamless coverage.
