Network Access
TCP/IP Model wherein the layer that represents data to the user plus encoding and dialog control
Application
TCP/IP Model wherein the layer that supports communication between diverse devices across diverse networks
Transport
TCP/IP Model layer that determines the best path through the network
Internet
TCP/IP Model layer that controls the hardware devices and media that make up the network

Session
Transport
Network
Data Link
Physical
OSI Model layer that performs services for the applications used by the end users
Application
OSI Model layer that providess data format information to the application.
Presentation
OSI Model layer that manages the sessions between users
Sessions
OSI Model layer that defines data segments and number them at the source, transfers the data, and reassembles the data at the destination.
Transport
OSI Model creates and addresses packets for end-to-end delivery through intermediary devices in other networks.
Network
OSI Model creates and addresses frames for host-to host delivery on the local LANs and between WAN devices.
Data Link
OSI Model transmits binary data over media between devices.
Physical
These are used to manage communication in data networks
Encapsulation Headers
PDU
Protocol Data Unit
These are used to identify the destination application
Port Numbers
These describe the various steps that must occur for successful communication
