Detailed explanation-3: -The Physical Layer (L1) is the lowest layer of the OSI model and provides hardware security. This layer is responsible for the actual physical connection between the devices by identifying the equipment involved in the data transfer. Layer 1 defines the hardware equipment, cabling, wiring, frequencies and pulses.
Detailed explanation-4: -The physical layer. The data link layer. The network layer. The transport layer. The session layer. The presentation layer. The application layer. This is the only layer that directly interacts with data from the user.
