WebThe first seven bytes of the preamble are all the same: 10101010. The last byte, or the Start of Frame byte is slightly different: 10101011. The 8 bytes of the preamble and the Start of Frame create a pattern of 64 bits. They are not officially counted as part of the Ethernet frame. The frame begins immediately after the Start of Frame, without ... WebSwitched, full-duplex Ethernet makes these considerations obsolete. However, Ethernet is built on compatibility - all physical layer variants can coexist and interact with each other. So, the minimum frame size was never changed and an ancient 10 Mbit/s half-duplex node can still work in a modern multi-gigabit network without much ado.
