the physical layer (layer 1) manages hardware connections, handles sending and receiving binary signals, and handles encoding of bits.
The physical layer is layer 1. It comprises the hardware (routers, repeaters, hubs, switches, etc.) that are used to form the physical basis of a network. They receive, process, and transmit raw electric (or optical) signals, rather than logical data packets.
The data link layer (layer 2) and the physical layer (layer 1) use the constructed frame.

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.
