It seems like you're asking for explanations of different types of routing. Here they are:

1. Centralized, Global Routing: In this type of routing, all routing decisions are made by a central node. This node has complete information about the network's topology and can therefore make optimal decisions about the path that data should take from one node to another.

2. Decentralized Routing: In contrast to centralized routing, decentralized routing involves each node making its own decisions about where to send data. Each node has information about its neighboring nodes, and uses this information to decide the best path for data.

3. Static Routing: This is a type of routing in which the routes are manually set and do not change. This can be useful in small networks, but it can be difficult to manage in larger networks where routes may need to change dynamically.

4. Dynamic Routing: In dynamic routing, routes are learned by the exchange of routing information between routers. This allows the network to adapt to changes, such as a node going offline or a new node being added.
