The ADDRESS resolution protocol (ARP) is used to associate the 32 bit IP address with the 48 bit physical address, used by a host or a router to find the physical address of another host on its network by sending a ARP query packet that includes the IP address of the receiver. The reverse address resolution protocol (RARP) ALLOWS a host to discover its INTERNET address when it KNOWS only its physical address.

Anonymous FTP enables users to connect to a host without using a valid login and password. Usually, anonymous FTP uses a login CALLED anonymous or guest, with the password usually requesting the USER's ID for tracking purposes only. Anonymous FTP is used to enable a large NUMBER of users to access files on the host without having to GO to the trouble of setting up logins for them all. Anonymous FTP systems usually have strict controls over the areas an anonymous user can access.

The DATA unit in the LLC LEVEL is called the protocol data unit (PDU). The PDU contains of four fields a DESTINATION service access point (DSAP), a source service access point (SSAP), a control field and an information field. DSAP, SSAP are addresses used by the LLC to identify the protocol stacks on the receiving and sending machines that are GENERATING and using the data. The control field specifies WHETHER the PDU frame is a information frame (I - frame) or a supervisory frame (S - frame) or a unnumbered frame (U - frame).
