it is a physical model, mathmatical model, and a conceptual model
First layer of the OSI model covers the cabling and electrical signaling. The first layer of OSI model is the physical layer. The physical layer also decides the transmission mode and physical media.
it comes in the first layer, or popularly known as the physical layer. must not be confused to be in datalink layer.
Examples of physical scientific models include the solar system model, the atomic model, and the double helix model of DNA. These models are used to represent physical phenomena and help scientists understand and predict the behavior of these systems.
Hubs and repeaters operate at the Physical Layer of the OSI Model. The Physical Layer is the first layer of the OSI Model.
A toy is a physical model.

A physical model is a tangible representation of a system, while a mathematical model is described using equations. Physical models are often used to understand real-world systems through hands-on interaction, while mathematical models are used for analysis and prediction. In simulation, physical models may involve physical components like scale models, while mathematical models use mathematical equations to simulate the behavior of a system.
A physical object can be represented by a 3D model.
There is no two-layered OSI model in CCNA. 7-layer there is (physical, link, network, transport, session, presentation, application). 4-layer there is (physical, network, transport, application), being the first an abstraction of physical+link and being the last an abstraction of session, presentation and application. This model is used because of the CCNA point of view, having no relevant meaning the abstracted layers.
A physical model could be a scaled-down replica of a building or bridge used to study its structural integrity. It provides a tangible representation that can be observed and tested to understand how the full-size structure would behave under different conditions.
