This tutorial provides an overview of the access, distribution, and core layers and explains two-tier and three-tier campus LAN designs. The OSI model describes seven layers that computer systems use to communicate over a network. Remember that a logical network diagram only records the nodes in the network which have an in-band, layer-3 presence. Here's how these layers work. The Open Systems Interconnection (OSI) model is a reference tool for understanding data communications between any two networked systems. This layer is the protocol layer that transfers data between nodes on a network segment across the physical layer. Explore why network diagrams are important, different types and how to draw. This is a conceptual model of a network On this layer, we don't really have a header, as it consists of single bits only.
