physical layer
The OSI model is a general model for networking . It has seven layer in total and each layer have some responsibilities. The layer that determines the communication mode is physical layer.

The physical layer is the lowest layer of the OSI Network Model. It is the part that physically transfers data from one location to another location. For instance, in your cell phone, it is the physical radio that encodes, transmits, and decodes your data packets. In a carrier pigeon network, it would be the carrier pigeons and their pigeon roosts.
The functions of the physical layer of the OSI model include data encoding, and transmission of the unstructured raw bit stream. It also includes description of the optical, mechanical, and electrical interfaces to the physical medium.
To effectively map communication to a model, several key layers should be considered: Physical Layer: This involves the transmission medium and hardware used for communication, such as cables, satellites, or wireless signals. Data Link Layer: This layer manages direct node-to-node data transfer, ensuring reliable communication over the physical layer. Network Layer: It handles routing and forwarding of data packets across the network, determining the best path for communication. Application Layer: This encompasses the protocols and interfaces that allow end-users to communicate effectively, such as email, messaging apps, or web services. Each layer plays a vital role in facilitating and enhancing the overall communication process.
In computing, the Open Systems Interconnection model partitions a communication system into seven layers. They are the physical layer, the data link layer, the network layer, the transport layer, the session layer, the presentation layer, and the application layer.
