Osi Model Physical Layer, Standardized by RFC 1122, which specifies its structure and behavior.

Osi Model Physical Layer, Defined as a four-layer architecture consisting of Application, Transport, Internet, and Network Access layers. It contains multiple input/output ports. Physical Layer - Physical layer of TCP/IP model is responsible for physical connectivity of two devices. The network layer breaks up segments from the transport layer into smaller units, called packets, on the sender’s device, and reassembling these packets on the receiving device. This layer manages the reception and transmission of the unstructured raw bit stream over a physical medium. For example, Layer 2 is the data link layer, which detects and corrects errors, as well as organizes the data into frames. It describes the electrical/optical, mechanical, and functional interfaces to the physical medium.
