Ethernet is a family of computer networking technologies used to connect electronic devices to Local Area Network (LAN) or Metropolitan Area Networks (MAN). Systems communicating over this device, divide data in shorter piece, which contain a destination address. Data transmitted through Ethernet also includes error-check so that damage of data can be detected and re-transmitted. Ethernet was found in 1973 by Xerox PARC which was termed as completely passive medium for the propagation of electromagnetic waves. Since then the technology of Ethernet has evolved to meet new bandwidth and interconnect appliances and other personal devices.
Certain devices that are used to provide Ethernet connection are-
- Outdoor Wireless Ethernet Radio: Commonly known as the Wifi, this robust device is used to helps one or more electronic device to connect with the Local Area Network (LAN). Many devices can simultaneously use Outdoor Wireless Ethernet Radio such as personal computers, smart phones etc. an access point can be made from a distance of 20 meters. AW2400xTR 2.4 GHz Outdoor Wireless Ethernet Radio is the widely used by different entities.
- Routers: Routers are whole setups of several devices, which incorporate a digital subscriber line modem or a cable modem and a Wi-Fi access point. Such set ups are often seen in homes and offices, which provide internet connections to all the devices, connected to them. all sizes of routers are easily available nowadays. Such devices are usually connected to provide a Wide Area Network (WAN).
- Optical fiber Cables: Optical Fiber Cables are created with one or more translucent fibers, which are coated, in a protective jacket. These cables are popularly used to provide Ethernet services in a far off distance. Optical Cables are used for their durability and long lasting properties.
Ethernet has developed over time to meet requirements of higher bandwidth, improved media access control and different physical media. Coaxial Cables used in Ethernet devices earlier was replaced by with point-to-point links and optical fiber cables.
