To establish a connection, TCP uses a 3-way handshake. Before a client attempts to connect with a server, the server must first bind to a port to open it up for connections: this is called a passive open. Once the passive open is established then a client may initiate an active open. To establish a connection, the 3-way (or 3-step) handshake occurs:

1. The active open is performed by sending a SYN to the server.
2. In response, the server replies with a SYN-ACK.
3. Finally the client sends an ACK back to the server.

At this point, both the client and server have received an acknowledgement of the connection.

 The communication b/w two tcp host are established by using 3-way handshaking.these are request , acknowldgement ,and data transfer.

transmitting host sent request to receiving host,receiving host sent ACK to senting host and then data is transfer from source to destination.
