WebDuring the course of the preamble it learns the correct phase, but in so doing it may miss (or gain) a number of bits. A special pattern (11), is therefore used to mark the last two bits of the preamble. When this is received, the Ethernet receive interface starts collecting the bits into bytes for processing by the MAC layer . Ethernet Header WebEthernet is the most common local area networking technology, and, with gigabit and 10 gigabit Ethernet, is also being used for metropolitan-area and wide-area networking. It is specified by various IEEE 802.3 specifications.
