The transport layer continues the delivery process by looking at the data from the application layer and dividing it into chunks. Each of these chunks is a collection of bytes. It then creates datagrams, or segments, out of these by adding the appropriate header to each of them. At the same time, this layer also verifies what kind of data it is and what protocol is necessary to send it. The two most common protocols here are UDP and TCP. Let's look at both.
