A description of ethernet and its usage

Ethernet standard IEEE The method used was similar to those used in radio systems, [d] with the common cable providing the communication channel likened to the Luminiferous aether in 19th century physics, and it was from this reference that the name "Ethernet" was derived.

The emphasis was on making installation of the cable easier and less costly. Comparison between original Ethernet and modern Ethernet The original Ethernet implementation: Many early researchers failed to understand these results.

In the worst case, where multiple active hosts connected with maximum allowed cable length attempt to transmit many short frames, excessive collisions can reduce throughput dramatically.


Later, Ethernet hubs largely gave way to network switchestheir more sophisticated and modern counterparts. However, a Xerox report in studied performance of an existing Ethernet installation under both normal and artificially generated heavy load.

Since then, the technology has continued to evolve and embrace new media, higher transmission speeds and changes in frame content -- e. Bridging and switching[ edit ] This section needs additional citations for verification.

Any device accessing a geographically localized network using a cable -- i. The MAC addresses are used to specify both the destination and the source of each data packet. Ethernet hub For signal degradation and timing reasons, coaxial Ethernet segments have a restricted size.

Gigabit Ethernet boasts speeds of 1, Mbps -- 1 gigabit or 1 billion bits per second -- Gigabit Ethernet GbEup to 10 Gbps, and so on. Alissa Irei and John Burke Share this item with your network: Ethernet initially ran over coaxial cableswhile a typical Ethernet LAN today uses special grades of twisted pair cables or fiber optic cabling.

Early experiments with star topologies called "Fibernet" using optical fiber were published by Repeaters and hubs[ edit ] Main article: The frame includes not just the payload of data being transmitted, but also: The lost data and re-transmission reduces throughput.

It can also offer a greater degree of network security and control than wireless technology, as devices must connect using physical cabling -- making it difficult for outsiders to access network data or hijack bandwidth for unsanctioned devices.

On reception of a transmission, the receiver uses the destination address to determine whether the transmission is relevant to the station or should be ignored. Ethernet is the traditional technology for connecting wired local area networks LANsenabling devices to communicate with each other via a protocol -- a set of rules or common network language.

Instead, whenever a network device sends a transmission via an input port, the hub copies the data and distributes it to all the available output ports. Ethernet frames are said to be self-identifying, because of the EtherType field. All computers trying to communicate share the same cable, and so compete with each other.

Early Ethernet connected multiple devices into network segments through hubs -- Layer 1 devices responsible for transporting network data -- using either a daisy chain or star topology.

Ethernet establishes link-level connections, which can be defined using both the destination and source addresses. A network interface normally does not accept packets addressed to other Ethernet stations.

Over time, the typical speed of each connection tends to increase. Please help improve this article by adding citations to reliable sources. Compared to wireless LAN technology, Ethernet is typically less vulnerable to disruptions -- whether from radio wave interference, physical barriers or bandwidth hogs.

From businesses to gamers, diverse end users depend on the benefits of Ethernet connectivity, including reliability and security. Engineers at Xerox first developed Ethernet in the s. Ethernet cables connect network devices to the appropriate routers or modems, with different cables working with different standards and speeds.

While a simple passive wire is highly reliable for small networks, it is not reliable for large extended networks, where damage to the wire in a single place, or a single bad connector, can make the whole Ethernet segment unusable. Early repeaters had only two ports, allowing, at most, a doubling of network size.

In this topology, collisions are only possible if station and switch attempt to communicate with each other at the same time, and collisions are limited to this link. Each computer communicates only with its own switch, without competition for the cable with others.Ethernet uses cables to connect computers; Wi-Fi is its wireless counterpart, and both technologies are used together.

See Wi-Fi and wireless router. 10/ and 10// Ethernet connects any computer or other electronic devices to its network as long as the device has an Ethernet adapter or network card. Network interface cards in the devices.

A network interface card is either integrated into the motherboard of the computer or installed separately in the device. It is important to note that each type of Ethernet, Fast Ethernet, Gigabit Ethernet, 10 Gigabit Ethernet, has its own preferred media types.

The most popular wiring schemes are 10BASE-T and BASE-TX, which use unshielded twisted pair (UTP) cable. This is similar to telephone cable and comes in a variety of grades, with each higher grade. An Ethernet cable is a popular type of network cable used for high-speed connections between two devices such as computers and routers on IP networks.

An Ethernet cable is a popular type of network cable used for high-speed connections between two devices. Metro Ethernet services are now offered by a wide range of service providers.

Some providers have extended • First, due to its broad usage in almost all networking products, the Ethernet interface itself is inexpensive. • Second, Ethernet services can often cost less than. Specified in the family of standards known as IEEEEthernet was originally developed by Xerox in the s.

Ethernet was initially designed to run over coaxial cables, but a typical Ethernet LAN now uses special grades of twisted pair cables, or fiber optical cabling.
