They are normally fasten to the header in front of the data field but can also be attached in the trailer or end of it. Every Protocol Data unit (PDU) fixes to the data by encapsulating it at every layer of the OSI model and each has a particular name (depending on the information provided in each header). On the receiving device, every neighbor layer just can read this PDU information. And after reading this information is stripped off and then the data is handed to the next upper layer.
