TCP/IP model
TCP/IP is part of the internet protocol suite, named after the two important layer protocols of the IP suite.
Transfer Control Protocol
The Transfer Control Protocol or TCP is the most common protocol used by the transport layer (also OSI Layer 4) of the IP suite. TCP is as connection oriented protocol, prior to sending data TCP first creates an end to end connection that allows for bidirectional communication across the connection. This allows the recipient of the datastream to both acknowledge receipt of data and to check for missing or corrupted data and request lost packets be retransmitted. Packets sent by TCP are ordered by segment numbering allowing them to be reordered if received out of order by the receiver, ensuring that data sent over switched networks which may result in out of order receipt is kept correctly ordered by the recipient.
