Well, the data might be a web request. The next thing that happens is we create a segment and that would either be your TCP or UDP header. And within that segment, we have the source and destination port address. The next part of encapsulation is adding the IP header. Now at the network layer, it's called a packet. And within that, we have a source and destination IP address. The last part of this frame formation is the frame header. And within that, of course, we have the MAC address.
