The Preamble consists of seven bytes all of the form 10101010, and is used by the receiver to allow it to establish bit synchronisation (there is no clocking information on the Ether when nothing is being sent).
The Start frame delimiter is a single byte, 10101011, which is a frame flag, indicating the start of a frame.

Stat Frame Delimiter (SFD) in Ethernet Frame
The Stat Frame Delimiter (SFD) in Ethernet Frame is a sequence of bits that is used to indicate the beginning of the Ethernet frame. It is also known as the Ethernet Start Frame Delimiter (ESFD) or the Ethernet Preamble.
The SFD is represented by the bit sequence 10101011.
When a device sends an Ethernet frame, it first sends the SFD followed by the Ethernet frame. The SFD is used by the receiving device to synchronize its clock with the transmitting device's clock.
Importance of SFD:
The SFD is important because it helps the receiving device to identify the beginning of the Ethernet frame. Without the SFD, the receiving device would not be able to distinguish between the beginning of the frame and the noise on the network.
Conclusion:
In conclusion, the Stat Frame Delimiter (SFD) in Ethernet Frame is a sequence of bits that is used to indicate the beginning of the Ethernet frame. It is represented by the bit sequence 10101011 and is important because it helps the receiving device to synchronize its clock with the transmitting device's clock and to identify the beginning of the Ethernet frame.
