Mesh topology
Each computer and network device is interconnected with one another.

Allow transmissions between each other . Mesh topology is difficult. It is expensive to have a redundant connections to every computer.  
Mesh topology is commonly used for wireless networks.

Hybrid Network topology
Used in Wide Area Networks. It integrates two or more different topologies.
Star-Ring and Star-Bus networks are the most common examples of hybrid networks.

Advantages of Hybrid Network Topology

1) Reliable : Fault detection and troubleshooting is easy.
2) Scalable: Its easy to increase the size of network by adding new components.
3) Flexible: Hybrid Network can be designed according to the requirements of the organization
4) Effective: Effectiveness maximized while weaknesses are neutralized.

Disadvantages

1) Complexity of Design:
2) Costly Hub: The hubs used to connect two distinct networks, are very expensive.
3) Costly Infrastructure: As hybrid architectures are usually larger in scale, they require a lot of cables, cooling systems, sophisticated network devices, etc.
