| | Ethernet - Wikipedia, the free encyclopedia |
 | | Ethernet was originally developed as one of the many pioneering projects at Xerox PARC. | | | Despite this, switched Ethernet should still be regarded as an insecure network technology, because it is easy to subvert switched Ethernet systems by means such as ARP spoofing and MAC flooding. | | | The Ethernet Version 2 or Ethernet II frame, the so-called DIX frame (named after DEC, Intel, and Xerox); this is the most common today, as it is often used directly by the Internet Protocol. |

| | Ethernet |
| | The ethernet data format is defined by RFC 894 and 1042. | | | This type of ethernet is subject to the 5-4-3 rule meaning there can be 5 network segments with 4 repeaters, and three of the segments can be connected to computers. | | | The frame type was developed prior to completion of the IEEE 802.3 specification and may not work in all ethernet environments. |

| | Ethernet |
| | A block of data transmitted on the Ethernet is called a "frame." The first 12 bytes of every frame contain the 6 byte destination address (the recipient) and a 6 byte source address (the sender). | | | Since short Ethernet frames must be padded with zeros to a length of 64 bytes, each of these higher level protocols required either a larger minimum message size or an internal length field that can be used to distinguish data from padding. | | | Since the maximum size of a packet on Ethernet is 1500 bytes, there was no conflict or overlap between DIX and 802 standards. |

| | Ethernet was originally developed by Digital, Intel and Xerox (DIX) in the early 1970's and has been designed as a 'broadcast' system, i.e. | | | The U/L bit is used in Token Ring A destination Ethernet MAC address starting with the octet '05' is a group or multicast address since the first bit (LSB) to be transmitted is on the right hand side of the octet and is a binary '1'. | | | Of course, in Ethernet, all source address will have a binary '0' since they are always individual. |

| | The design goals for Ethernet were to create a simply defined topology that made efficient use of shared resources, was easy to reconfigure and maintain, provided compatibility across many manufacturers and systems, while keeping the cost low. | | | The original Ethernet specification began in the early 1970's by Xerox PARC, and was eventually improved upon by Digital Equipment Corporation, Intel, and Xerox (DIX) in 1980 with the release of Ethernet Version 1. | | | In Ethernet networks, any frame shorter than the minimum 64 bytes but with a valid CRC is considered a runt. |

| | These 12 hex digits consist of the first/left 6 digits (which should match the vendor of the Ethernet interface within the station) and the last/right 6 digits which specify the interface serial number for that interface vendor. | | | For example, DEC is assigned the vendor component 08-00-2B, so multicast addresses assigned by DEC have the first 24-bits 09-00-2B (since the multicast bit is the low-order bit of the first byte, which is "the first bit on the wire"). | | | If there is a global algorithm for which addresses are designated to be physical (in a chipset) versus logical (assigned in software), or globally-assigned versus locally-assigned addresses, some of the known addresses do not follow the scheme (e.g., AA0003; 02xxxx). |
