-	\item The non-profit organization \textbf{Internet Engineering Task Force} (IETF) issues standards concerning the internet. The standards are called \emph{Request For Comment} (RFC) and are available for everyone for free. Example standards: Internet Protocol (IP), Hypertext Transfer Protocol (HTTP)

-Protocol layers add own information to the data received from the upper layer. This additional information is required to provide the protocol's functionality. For example, the Internet Protocol (IP) needs to add the source and destination address, so that the packet can be routed to the correct endpoint. One can imagine this like data which is written on a letter, which is put into an envelope, which itself is put into another envelope, and so on.
