Question

This layer corresponds to the network hardware (cabling, media). This layer determines how binary data is translated into electrical, optical, or other types of physical signals transmitted between systems

Answer 1

This description refers to the physical layer in the OSI model, which is the first layer in the model and is responsible for the physical transmission of data between devices. The physical layer is concerned with the transmission of data over a physical medium, such as copper wire or fiber optic cable, and is responsible for translating the data into a form that can be transmitted over the medium. The physical layer is also responsible for establishing, maintaining, and terminating connections between devices, as well as determining the type and speed of the transmission.
