Transmission Control Protocol (TCP) arrives out of order. What allows the data to be put back together in the correct order?

Reliability feature in transport layer ensures correct order.

Explanation:

TCP (Transmission Control Protocol) is a communication protocol over network. TCP has a layered architecture and transport layer controls the data transmitted arrives in correct form. This is called reliability feature.

Control data header at transport layer ensures correct delivery. It tracks the transmitted data and re-transmits in case of en error.

The Transport Layer

Explanation:

The transport layer provides a method of delivering data across the network in a way that ensures the data can be properly put back together on the receiving end. The transport layer provides for the segmentation of data, and the controls necessary to reassemble these segments into the various communication streams.
