The preamble is a 64-bit (8 byte) field that contains a synchronization pattern consisting of alternating ones and zeros and ending with two consecutive ones. After synchronization is established, the preamble is used to locate the first bit of the packet. The preamble is generated by the LAN interface card.

What else can I help you with?
Within ethernet frame types what signals to the receiving node that data is incoming and indicates when the data flow is about to begin?
preamble
What is the difference between the Ethernet frame preamble field and the IEEE 802.3 preamble and start of frame Delimiter fields?
1 byte for frame delimiter field in IEEE 802.3
What is the the purpose of the preamble in an Ethernet frame?
It gives the receiving NIC time to realize a frame is coming and to know when the frame starts..
Which field in an Ethernet frame is used for synchronization?
In an Ethernet frame, the field used for synchronization is the preamble. The preamble consists of 7 bytes of alternating 1s and 0s, followed by a 1-byte Start Frame Delimiter (SFD). This sequence allows the receiving device to synchronize its clock to the incoming signal, ensuring proper interpretation of the subsequent data in the frame.
What is the purpose of the 7-byte preamble and 1-byte start-of-frame delimiter on an Ethernet frame?
The purpose is the preamble signals to the receiving node that data is incoming and indicates when the data flow is about to begin. The SFD (start-of-frame delimiter) identifies where the data field begans.
What protocols are in the Ethernet frame?
The ethernet frame carries the IP (Internet Protocol) The Ethernet frame is made up of the following: 7 BYTE PREAMBLE 1 Byte "Start OF Frame" delimiter 6 byte destination address 6 byte source address 2 byte length or type 46 - 1500 bytes variable 802.2 or ethernet header and data 4 byte Frame Check sequence
What part of the Constitution lists six goals for the national government?
The Preamble. (:
What is the constitutions opening segment called?

What is the definition for preamble?
The word preamble means introduction. Words that are synonyms for preamble are prelude and preface. The word preamble is a noun.
Aspects of Ethernet have remained relatively unchanged over the years?
Ethernet has maintained key characteristics such as its frame structure, which includes a preamble, destination and source MAC addresses, and a frame check sequence for error detection. The use of a shared communication medium and the concept of collision detection (in earlier versions) have also persisted. Additionally, Ethernet's adaptability to various physical media and speeds, from 10 Mbps to 100 Gbps and beyond, has allowed it to remain relevant while retaining its foundational principles. These enduring aspects contribute to Ethernet's robustness and widespread adoption in networking.
Wireshark does not display the preamble field of a frame header . what does the preamble contain?
The preamble in a frame header, particularly in Ethernet frames, is a sequence of bits that serves to synchronize the sender and receiver. It typically consists of 7 bytes of alternating 1s and 0s, followed by a 1-byte Start Frame Delimiter (SFD) that indicates the start of the actual frame data. This synchronization allows the receiving device to correctly interpret the incoming data by establishing timing and ensuring that it is ready to process the frame. Wireshark does not display the preamble because it is not part of the actual frame data that is transmitted over the network.
What is an antonym for preamble?
The opposite of preamble is postscript
