WebThe preamble of an Ethernet frame consists of a 56-bit (7-byte) pattern of alternating 1 and 0 bits, which allows devices on the network to easily detect a new incoming frame. The SFD is designed to break this pattern, and signal the start of the actual frame. Share. WebJul 26, 2024 · Ethernet frame. A basic Ethernet frame contains six pieces of information: the MAC address of the frame’s recipient, the MAC address of the sending system, the type of the data, the data itself, a pad (if needed), and a frame check sequence. Appended to the front of the frame is the preamble.
