Ethernet is a network system that created and patented the company Xerox. Ethernet is the preferred method of implementation of CSMA / CD (Carrier Sense Multiple Access with Collision Detection), which developed the project in 1960 in the wireless ALOHA University of Hawaii over coaxial cable.
Standardization system Ethernet conducted since 1978 by the IEEE. Speed transmission of data in Ethernet until now is 10 to 100 Mbps. While in general there is a market Ethernet speed of 10 Mbps series called 10Base. There are various types of 10Base are: 10Base5, 10Base2, 10BaseT, and 10BaseF which will be explained further later. In the method, CSMA / CD, a host computer which will send data to the network first ensure that the network is not used to transfer from the host computer and by the other. If the checks found during the transmission of data and other collision occurred (Collision), the host computer is required to repeat the application (request) on the lapse of time that is done randomly (random). Thus effective network can be used alternately. To determine the position where a host computer is located, then each device is given Ethernet address (address) along a unique 48 bit (only one in the world). Address information stored in the chip, which is usually visible on the computer at the start in order based on the number 16.
