The Transmission Control Protocol / Internet Protocol or TCP/IP Architecture.
The Transmission Control Protocol / Internet Protocol or TCP/IP Architecture defines a series of software and hardware layers, that when combined correctly, provide data transmission between various devices with a degree of consistency and robustness.
The table below displays the layers defined within the TCP/IP Architecture.
| 4 | Application Layer |
| 3 | Transport Layer The TCP/IP transport layer is equivalent to the transport layer in the OSI model, and contains not only the TCP service, but the UDP service too. |
| 2 | Internet Layer |
| 1 | Network Access Layer Contains the network, data link and physical layers of the OSI model |
