Want this question answered?
header board is a the board on the front of the trailer, or the board that is on the tractor behind the cab/sleeper. this is made of metal and is to prevent the load on trailer coming thru the cab in the event an accident or other emergency
Frame Header - Network Header - Transport Header - Data - Frame Trailer
header, packet(data), and trailer
b Node having header and trailer in the list
removes the Ethernet header and trailer
the answer is a Header,the a Payload, then last is the Trailer
A header board, is a vertical structure on the front of flat-bed trailers. Its purpose is to keep the freight from moving forward onto the cab. It is humorusly called a headache rack (it prevents the load from shifting forward therefore prevents the driver from getting a "headache" when the cab is crushed. The terminology is different for a a dry-van trailer or a refrigerated trailer, or what is sometimes called a "box" trailer, wherein the front is called a bulkhead. Sometimes these two terms are incorrectly interchanged by drivers who lack trucking knowledge.
It encapsulates with a header and a trailer to create a frame.
the ethernet frame what it concist of
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).
The Header.
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.
