The Basic Header contains information about the source of the message. The Application Header contains information about the message type and the destination of the message.
The contents of the trailer block include both user information (checksum, message authentication, proprietary authentication, and so on) and system information (delayed message, message reference, possible duplicate message, and so on).

What is Ethernet header?
An Ethernet header is a portion of data that precedes the payload in an Ethernet frame, containing essential information for data transmission over a network. It typically includes the source and destination MAC addresses, the EtherType field to indicate the protocol used in the payload, and other control information. The header enables devices on a local area network (LAN) to identify and process the incoming frames correctly. In standard Ethernet frames, the header is usually 14 bytes long.
What is the correct order for PDU encapsulation?
Frame Header - Network Header - Transport Header - Data - Frame Trailer
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.
What is tcpip header and trailer?
An Ethernet frame has a 14 byte header, a data section, and a 4 byte trailer 14 byte header consist of destination address, source address and type The trailer is for CRC (Cyclic redundancy Check) An Ethernet frame can contain an IP and TCP PDU. IP header most important parts consists of (Version,IHL, Total length,Protocol, source and destination address) In details (Version,Header length,Differentiated services field, total Length, Identification, Flags, fragment offset, Time to live, protocol, header checksum, source and destination address). TCP header most important parts consists of (Source port, Destination port and header Length) In details (Source Port, Destination Port, Sequence number, Acknowledgment number, Header length,Flags,Window and check sum). The details of the IP and TCP header have been taken from a Network protocol Analyzer Wireshark on my own pc.
Which protocol header carries the physical address of host?
Ethernet
Which protocol's header includes the source MAC address?
The Ethernet protocol's header includes the source MAC address.
What is the relationship between an Ethernet version 2 header and the header of an 802.3 frame?
The two headers are the same length as each other.
