Preamble - seven bytes of alternating 0s also 1s to notify receiver of incoming frame and to provide synchronization
SFD (Start frame delimiter) - one byte signalling the beginning of the frame
DA (Destination address) - six bytes containing the physical address of the next destination if packet must reach another LAN this field contains the physical address of the router upon reaching the target network field then contains the physical address of the destination device
SA (Source address) - six byte field containing physical address of last station to forward packet sending station or most recent router

Length or type - Two bytes indicating number of bytes in coming PDU if fixed length can indicate type
Data - 46 to 1500 bytes
CRC - CRC-32 error detection information
