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.

A layer 1 device refers to hardware that operates at the physical layer of the OSI model, which is responsible for the transmission and reception of raw bit streams over a physical medium. Examples of layer 1 devices include cables (like Ethernet cables), network interface cards (NICs), and hubs. These devices do not interpret the data being transmitted; they simply facilitate the connection and transfer of signals between devices in a network.
