Ethernet Frames
The original 10 Mbps Ethernet specification defined a simple frame format where each frame is composed of five fields.
-
The Ethernet frame starts with a preamble (not shown in the figure below) that’s used by the physical layer of the receiver to synchronise its clock with the sender’s clock.
-
The first field of the frame is the destination address. As this address is placed at the beginning of the frame, an Ethernet interface can ...
