The transport layer's purpose is to establish a logical end to end connection between two systems, segment data received from the upper layers of the OSI model, and to make sure the data gets to the destination in the correct order and free of errors.
At the Transport Layer, there are two methods for transporting data: connection-oriented, referring to TCP, and connectionless, referring to UDP. We'll take a much more detailed look at TCP and UDP later in this section.
