Physical and MAC addressing are found in the OSI layer 2?
Layer 2 addressing not required for this topology
Data Link
The role is to transfer frames to packets
The OSI model has seven layers whereby each layer has its function. The Data Link Layer is responsible for addressing data messages so that they reach their destination correctly.
Data link layer
Layer 2 addressing not required for this topology
Data link layer transforms the physical layer and makes it appear error free. Data link layer is responsible for physical addressing. It has some other functions like error control, flow control and access control.

Data Link
The Physical layer is responsible for the actual hardware connection. The physical addressing is handled by the Data Link Layer.

* addressing * error detection * frame delimiting
The data link layer is responsible for ensuring the trustworthy transmission of data across a physical link. It handles physical addressing, line discipline, network topology, error notification, and ordered delivery of frames. By managing these functions, the data link layer ensures that data packets are reliably transmitted between directly connected devices.
The Internet Protocol (IP) provides routing of data from the source to a destination by defining the packet structure and addressing scheme. It operates at the network layer, facilitating the movement of data between the data link layer and the transport layer. IP routes packets of data across interconnected networks, ensuring they reach their intended remote destinations. Its primary function is to handle addressing and routing, enabling effective communication across diverse network architectures.
The data link layer header contains the source's physical address. It refers the address that is found in the Network Interface Card.
