Explain the switch filtering function.?

What will be an ideal response?


As a frame of data moves across the first local area network and enters the switch, the switch examines the source and destination addresses that are stored within the frame. These frame addresses are assigned to the network interface card (NIC) when the NIC is manufactured. (All companies that produce NICs have agreed to use a formula that ensures that every NIC in the world has a unique NIC address.) The switch, using some form of internal logic, determines if a data frame's destination address belongs to a workstation on the current segment. If it does, the switch does nothing more with the frame, because it is already on the appropriate segment. If the destination address is not an address on the current segment, the switch passes the frame on to the next segment, assuming that the frame is intended for a station on that segment. Additionally, the switch can check for transmission errors in the data by performing a cyclic checksum computation on the frame.?

De?ne triggers that ?re when a student drops a course, changes her major, or when her grade average drops belowa certain threshold. (For simplicity, assume that there is a function, grade_avg(), which takes a student Id and returns the student average grade.)

The action part of these triggers is uninteresting—just an insertion of a record into the log table, as we saw in earlier problems. We give an example of the last trigger.
