D. MAC address
A is the correct answers
1) The IP Address is used to uniquely identify the desired host we need to contact. This information is not shown in the above packet because it exists in the IP header section located right above the TCP header we are analysing. If we were to expand the IP header, we would (certainly) find the source and destination IP Address fields in there.
2) The 2nd important aspect, the port number, allows us to identify the service or application our data or request must be sent to, as we have previously stated. When a host, whether it be a simple computer or a dedicated server, offers various services such as http, ftp, telnet, all clients connecting to it must use a port number to choose which particular service they would like to use.
The best way to understand the concept is through examples and there are plenty of them below, so let’s take a look at a few, starting from a simple one and then moving towards something slightly more complicated.
