I want to dispense my knowledge on progress called encapsulation.

Let's say we have some data on 7th layer of OSI model, or 5th layer of TCP/IP model, the data has been created! On Transport_layer data gets his first header and depending on application layer header should be send as UDP or TCP. This is example of UDP header:

more info on UDP. If it's TCP than header will look like this:

more info on TCP.

data that goes through Transport layer is called segments.
