Transport layer .....
The transport layer provides flow control and sequencing.
physical layer
In the transport layer of the OSI model, sequence numbers are primarily associated with the Transmission Control Protocol (TCP). Sequence numbers are used to ensure the correct order of data segments and to facilitate reliable data transmission by allowing the receiver to reassemble the data in the correct sequence. Each byte of data in a TCP segment is assigned a unique sequence number, which helps in tracking the data flow and managing retransmissions in case of packet loss.

Layer 2 - The Data Link Layer Layer 2 of the OSI model provides error-detection capability
Network Layer This layer addresses the data. It adds an IP address which allows our data to flow across networks. The protocols involved in this layer are IP and IPX. Data Link Layer This layer provides the functional and procedural means to transfer data. It also corrects any errors that may occur in the Physical layer. The protocols used at this layer are media access control and logical link control.
Data Link
The layer that provides transparency of data between the client and server is the application layer in the OSI model. It allows applications to communicate over a network without needing to understand the underlying complexities of the network architecture. This layer ensures that data is formatted and delivered correctly, enabling seamless interaction between clients and servers.

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.
