IP vs TCP

Which means Internet protocol which works by exchanging groups of information called packeds. Packets are short sequences of bytes consisting of a header and a body. Header describes destination and which router to use for transformation.And in cases of Congestion, IP can discard packets and for efficiency two packets can use different routes.
Tcp use ip and provide simpler interface to applications by hiding most of the packets structures and minimize network congestion and retransmit discarded packets.
