The "physical layer" i.e, the first layer of the network model includes specifications for cables and connectors and how signals are sent over these connections
Explain the network model.
The network model was created as a flexible method of expressing things and their relationships in the database. The schema is unique in that it is not limited to being a hierarchy or lattice when considered as a graph in which object types are nodes and relationship types are arcs.
The network model schema, in contrast to other database models, is not restricted to being a lattice or hierarchy; instead, a graph in place of a hierarchical tree allows for more straightforward linkages with the nodes. The network model has a key benefit which is its capacity to overcome the hierarchical model's lack of flexibility, which is meant to be a direct progression.
