A description of ethernet and its usage

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. Performance on real networks is significantly better.

Bridging and switching[ edit ] This section needs additional citations for verification. Alissa Irei and John Burke Share this item with your network: Network engineers use BASE-T largely to connect end-user computers, printers and other devices; to manage servers and storage; and to achieve higher speeds for network backbone segments.

Since then, the technology has continued to evolve and embrace new media, higher transmission speeds and changes in frame content -- e.

The short length of yellow 10BASE5 cable has one end fitted with a N connector and the other end prepared to have a N connector shell installed; the half-black, half-grey rectangular object through which the cable passes is an installed vampire tap.

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 was originally based on the idea of computers communicating over a shared coaxial cable acting as a broadcast transmission medium.

Ethernet defines two units of transmission: Any device accessing a geographically localized network using a cable -- i. Once repeaters with more than two ports became available, it was possible to wire the network in a star topology.

Ethernet standard IEEE 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.


Over time, the typical speed of each connection tends to increase. In full duplex, switch and station can send and receive simultaneously, and therefore modern Ethernets are completely collision-free. The coaxial cable was replaced with point-to-point links connected by Ethernet repeaters or switches.

The total throughput of the repeater is limited to that of a single link, and all links must operate at the same speed. Ethernet establishes link-level connections, which can be defined using both the destination and source addresses.

Engineers at Xerox first developed Ethernet in the s. Each computer communicates only with its own switch, without competition for the cable with others.

Each frame is wrapped in a packet that contains several bytes of information to establish the connection and mark where the frame starts. Early experiments with star topologies called "Fibernet" using optical fiber were published by Comparison between original Ethernet and modern Ethernet The original Ethernet implementation: Early repeaters had only two ports, allowing, at most, a doubling of network 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. Ethernet initially ran over coaxial cableswhile a typical Ethernet LAN today uses special grades of twisted pair cables or fiber optic cabling.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. 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.

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 uses a bus or star topology and supports data transfer rates of 10 Mbps.

The Ethernet specification served as the basis for the IEEE standard, which specifies the. 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.
