Physical Layer
The Physical layer of the OSI model is responsible for defining the characteristics of the transmission medium between two devices. This layer deals with the physical connection between devices and the transmission of raw data bits over a physical medium. Here's why the Physical layer defines the type of transmission medium:
- Transmission Medium: The Physical layer specifies the characteristics of the transmission medium, such as whether it is wired or wireless, the type of cable used, and the signaling method.
- Physical Connections: This layer determines how devices are connected physically, including the type of connectors, pins, and voltage levels used for communication.
- Data Encoding: The Physical layer also deals with data encoding and modulation techniques, which are essential for transmitting data over the chosen medium.
- Bit Transmission: At this layer, data is transmitted in the form of raw bits without any higher-level protocol information. It simply ensures that the bits are sent and received accurately.
In conclusion, the Physical layer of the OSI model plays a crucial role in defining the type of transmission medium between devices by specifying the physical aspects of the communication link. It serves as the foundation for higher layers to establish reliable communication between networked devices.

Simplex, half-duplex and full-duplex are the three transmission directions that are defined by the physical layer between two devices. Additionally, connecting gadgets to media is a concern.
