| Layer 1 (OSI model) | Physical |
| Layer 2 (OSI model) | Data Link |
| Layer 3 (OSI model) | Network |
| Layer 4 (OSI model) | Transport |
| Layer 5 (OSI model) | Session |
| Layer 6 (OSI model) | Presentation |
| Layer 7 (OSI model) | Application |
| Physical Layer | Layer 1 The Physical layer of the OSI model sets standards for sending and receiving electrical signals between devices. |
| Protocols at the Physical layer identify: | |
| Data Link Layer | Layer 2 The Data Link layer defines the rules and procedures for hosts as they access the Physical layer. |
| These rules and procedures specify or define: | |
| Network Layer | Layer 3 The Network layer describes how data is routed across networks and on to the destination. |
| Network layer functions include: | |
| Transport Layer | Layer 4 The Transport layer provides a transition between the upper and lower layers of the OSI model, making the upper and lower layers transparent from each other. |
| Transport layer functions include: | |
| Session Layer | Layer 5 The Session layer's primary function is managing the sessions in which data is transferred. |
| Functions at this layer include: | |
| Presentation Layer | Layer 6 The Presentation layer formats or "presents" data into a compatible form for receipt by the Application layer or the destination system. |
| Specifically, the Presentation layer ensures: | |
| Application Layer | Layer 7 The Application layer integrates network functionality into the host operating system, and enables network services. The Application layer does not include specific applications that provide services, but rather provides the capability for services to operate on the network. Most Application layer protocols operate at multiple layers down to the Session and even Transport layers. However, they are classified as Application layer protocols because they start at the Application layer (the Application layer is the highest layer where they operate). |
| Services typically associated with the Application layer include: |
