TCP/IP Architecture

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
