The main function of TCP control the data communication process in which identification of IP address, data checking, transfer in right manner, forwarding message in right direction for right destination. The main function of TCP control the data communication process in which identification of IP address, data checking, transfer in right manner, forwarding message in right direction for right destination. TCP maintains a logical connection between the sending and receiving computer systems. TCP detects any problems in the transmission quickly and take some action to correct them.
