Logical network definition
Logical network refers to the way a network appears to a user, without regard to the actual physical layout or connection methods. It's a conceptual design that includes the organization and configuration of network services such as IP addressing, routing protocols, network security, and access control.

Logical network types:
- Flat network. This is the simplest form of a network where each node or device on the network is connected to a common medium, usually a network switch, without any hierarchy or segmentation. It’s easy to set up, but it doesn’t scale well because it lacks the control and flexibility of other types of networks.
- Hierarchical network. This kind of network is set up in a tree-like structure, where some nodes are more important than others and data must pass through those nodes to reach others. This structure is organized, efficient, and scalable.
- Star network. All nodes are connected to a central node, often a switch or a hub. This setup allows easy addition or removal of nodes without disrupting the entire network.
- Mesh network. Every node is connected to every other node. This network offers high redundancy and reliability because if one connection fails, data can travel through a different route.
- Bus Network. All devices are connected along a single cable, the bus, with two endpoints. It is relatively easy to install but doesn't scale well.
