The transport layer provides flow control and sequencing.

physical layer
The Transport Layer and Data Layer can provide error detection and correction at the different levels of data transmission. Network layer can also correct errors if it detects them.
The application layer.
To reassemble the segments into data.
The median is the "middle" number in a set of data or a sequence. If you have the sequence 2,3,4,5,6 4 would be the median.

It is used to keep track of the data packets being sent to and from hosts.
