Answer Posted / sreenivasa rao
TCP (Transmission Control Protocol) works to provide the
reliable data transmission. To be able to do that, the TCP
first establishes a connection using a 3 way handshake
method. Once the connection is established, the data is
transmitted. But is it enough for providing a reliable data
transmission? Probably not!
TCP provides the function of retransmission if the data is
lost while being transmitted. For doing this an
acknowledgment receipt is required before the sender can
send more data.
