802.3 is a technology that can support the [[IEEE 802.1]] network architecture.   

802.3 is a technology that can support the [[IEEE 802.1]] network architecture.   

The maximum [[packet]] size is 1518 bytes, although to allow the Q-tag for [[Virtual LAN]] and priority data in [[802.3ac]] it is extended to 1522 bytes. If the upper layer protocol submits a [[protocol data unit|PDU]] (Protocol data unit) less than 64 [[byte|bytes]], 802.3 will pad the data field to achieve the minimum 64 bytes.

Although it is not technically correct, the terms "[[packet]]" and "[[frame (telecommunications)|frame]]" are used interchangeably. The <nowiki>ISO/IEC 8802-3 ANSI/IEEE</nowiki> 802.3 Standards refer to MAC sub-layer frames consisting of the Destination Address, Source Address, Length/Type, data, and [[Frame Check Sequence|FCS]] fields. The Preamble and [[Start Frame Delimiter|SFD]] are (usually) considered a header to the MAC Frame. This header plus the MAC Frame constitute a "Packet".

What is defined in earlier IEEE 802.3 standards is often confused for what is used in practice: almost any network frame you can find on a LAN will be an Ethernet II frame, since the [[Internet protocol suite]] will use this format, with the type field set to the corresponding IETF protocol type.  IEEE 802.3x-1997 allows the 16-bit field after the MAC addresses to be used as a type field or a length field, so that Ethernet II frames are also valid 802.3 frames in 802.3x-1997 and later versions of the IEEE 802.3 Ethernet standard.
