WebBoth the source and destination hosts are identified with a 48-bit address. The packet type field serves as the demultiplexing key; it identifies to which of possibly many higher-level protocols this frame should be delivered. Each frame contains up to 1500 bytes of data. WebEthernet packets with less than the minimum 64 bytes for an Ethernet packet (header + user data + FCS) are padded to 64 bytes, which means that if there's less than 64- (14+4) = 46 bytes of user data, extra padding data is added to the packet. Beware: the minimum Ethernet packet size is commonly mentioned at 64 bytes, which is including the FCS. dark stuff in ear
