An ip packet to be transmitted by ethernet is 60 bytesif LCC is not in use is padding needed in ethernet and if so how many bytes?

Yes, padding is needed for an Ethernet frame if the IP packet is only 60 bytes and the Length/Type field (LCC) is not in use. Ethernet frames must be at least 64 bytes in total, including the header and trailer. Since the Ethernet header is 14 bytes and the trailer (Frame Check Sequence) is 4 bytes, the total without padding is 78 bytes. Therefore, 0 bytes of padding are needed because the total frame size exceeds the minimum requirement.
