TCP (Transmission Control Protocol)
The TCP (Transmission Control Protocol) is an internetwork connection-oriented protocol that corresponds
to the OSI Transport layer. TCP provides full-duplex, end-to-end connections. When the end-to-end
communication acknowledgement is not required, the UDP (User Datagram Protocol) can be substituted for
the TCP at the Transport (host-to-host) level. TCP and UDP operate at the same layer.
The UDP is a connectionless oriented protocol.
