The physical layer is the most basic network layer, providing only the méans of transmitting raw bits rather than packets over a physical data link connecting network nodes. No packet héaders nor trailers are consequently added to the data by the physical layer. The bit stream may be grouped into code words or symbols, and converted to a physical signal, which is transmitted over a physical transmission medium. The physical layer provides an electrical, mechanical, and procedural interface to the transmission medium. The shapes of the electrical connectors, which frequencies to broadcast on, what modulation scheme to use and similar low-level paraméters are specified here. An analogy of this layer in a physical mail network would be the roads along which the vans carrying the mail drive.

Physical signaling sublayer

In a local area network (LAN) or a metropolitan area network (MAN) using open systems interconnection (OSI) architecture, the physical signaling sublayer is the portion of the physical layer that:
