Transmission Control Protocol (TCP)

The Transmission Control Protocol (TCP) is the most commonly used protocol for
exchanging data between communication devices using Ethernet. Unlike UDP, the
TCP protocol guarantees reliable transmission between applications. TCP also
distinguishes data for multiple, concurrent applications running on the same host.
A data message sent as a TCP/IP message means that the higher layer Transmission
Control Protocol assembles the message or file into smaller packets. These are then
transmitted over the Internet and received by a TCP layer which reassembles the
packets into the original message.
