Introduction to TCP

Exchange of data can be described as one of the primary functions of internetworks. However, to establish a smooth communication mechanism among networks that use diverse hardware and software configurations, a control mechanism that manages modification of data to a format compatible for data transmission must be established. The control mechanism must also manage the actual transfer of data over the diverse networks. The Transport layer, which contains Transmission Control Protocol (TCP) and User Datagram Protocol (UDP), implements such a mechanism.
