| Function (if applicable)
| Allows hardware to interact with physical device
| Communication of sending and receive data from physical hardware.
| Data link layer
| This layer handles errors that are could be formed in the physical layer.
| Flow control for Synchronous
| Network layer
| Allows procedures which allow data to be transferred from one network to another.
| Allows, maintains and closes network links between networks.
| Transport layer
| End to end error recovery
| Combats error handling and flow of network traffic.
| Session layer
| Connection and session coordination.
| Allows users to setup control and end a link and is in charge of user authorization.
| Presentation layer
| Changes data from the application layer to typical formats and encrypts information
| Application layer
| Supports applications and end-users.

| Data Sent or received to occur in Regular intervals
| Data that is send and received irregular intervals.
| The amount of information that can be carried on a medium.
| Point-to-point topology
| Two nodes that are linked together directly on a network
| Used in a Peer-to-peer network
