Q

Transmission Control Protocol (TCP) is a connection-oriented protocol using a three-way handshake, which is a set of initial steps required to establish network connection. TCP supports retransmission of lost packets, flow control (managing the amount of data that is being sent), and sequencing (rearranging packets that arrived out of order).
