The Transmission Control Protocol (TCP) is used to provide reliable, in-order delivery of messages over a network.
Reasons for TCP
The Internet Protocol (IP) works by exchanging groups of information called packets. Packets are short sequences of bytes consisting of a header and a body. The header describes the packet’s destination, which routers on the Internet use to pass the packet along, in generally the right direction, until it arrives at its final destination. The body contains the application data.
