TCPIPTutorial
In the TCP/IP protocol suite, TCP is the intermediate layer
between IP below it, and an application above it. Using TCP,
applications on networked hosts can establish reliable
connections to one another. The protocol guarantees in-order
delivery of data from the sender to the receiver
Streams of data called segments are used by TCP peers to
speak to each other. The segments can be quite large, so TCP
breaks up the segments into smaller units of data. These units
are encapsulated in the TCP packet that is passed to the IP
protocol. Each unit of data is assigned a sequence number,
which becomes part of the TCP packet. At the receiving end, the
TCP module uses the sequence numbers in the packet to
reconstruct the user data in the correct order.
