PHY (Physical Layer Device - OSI
Layer 1)
EEPROM
The physical device layer, the lowest layer of the OSI reference model, refers to
the physical components of the network: cables, connectors, etc. OSI, the
Operating Standard Interface, is a framework upon which networking standards are
arranged. It is commonly diagramed as a layered pyramid with the physical layer,
Layer 1, on the bottom of the pyramid, and layer 7, the application layer, at the top.
