What is a data frame? Show the layout of a data frame from a lower layer protocol (name the protocol) and describe its fields. A data frame is used to describe a transmission packet in bit oriented protocols. It usually includes the original data with each higher layer's header, and data link layer its own header/trailer. The header has information about the destination where the data is going. Its purpose is to make sure each data reaches the correct destination. Here is an example of a DIX 8 Preamble 6 Dest. Addr. 6 Source Addr. 2 Type 46-1500 Data 4 CRC DIX data frame use a 6 octets to synchronize the transmitter and receiver. Receiver uses the synchronization bits to sense the incoming message and establish time or synchronization with the transmitter. The preamble is a bit pattern used to identify the start of the frame. The next field after the Preamble field is the 48 bits destination address, which identified the receiver. The field after...
