Computer 1 is accessing the Address Resolution Protocol (ARP) table in Router Y to look up the destination MAC address that corresponds to a specific IP address for local network communication.
When computer 1 is looking at the Address Resolution Protocol (ARP) table of Router Y, it is seeking the destination MAC address associated with an IP address. The ARP table, or ARP cache, is a list that maps IP addresses to their corresponding MAC addresses, enabling the translation necessary for packet delivery within a local network segment. The MAC address, also known as a physical address or hardware address, is a unique identifier assigned to network interfaces for communications at the Data Link layer of the OSI model.
In contrast, the port number is used at the Transport layer to identify specific applications or services running on a host, and the Attlee value appears to be a typographical error or irrelevant term to this context.
