Why did Ethernet emerge as the LAN standard?

Ethernet is a system whereby several computer systems are connected together to form a local area network (LAN) which has protocol that controls the passing of information and also it avoids simultaneous transfer of information by more than one systems. Ethernet is specified in a standard IEEE(Institute of Electrical and Electronic Engineers) 802.3, it was established by Xerox from a specification known as Alohanet (Palo Alto Research Center Aloha network) and it was developed later on by Xerox, DEC, AND Intel. Ethernet uses coaxial cable or twisted pair of wires. The most used Ethernet systems are 10BASE-T which has a transmission speed of up to 10megabits per second

A local area network (LAN) is where two or more computers are interconnected using software and hardware. When LAN is installed in a home or office it enables sharing of files, resources and internet connection by different computers. LAN can be either wireless or wired. If the LAN is wired then it requires Ethernet cables to connect all computers on the network to a main switch.

The Ethernet emerged as the LAN standard because of the following; the system is cost saving since one server which is connected to the switch can be used by different computers instead of each computer having its own server; Ethernet enables the computers to use one server. LAN is based on the emerging IEEE-802.3 10Base T standard that allows the movement of data over standard phone line at full 10m-bps rate this has made the Ethernet to emerge as a LAN standard. Also the length of twisted- pair cable which 10Base T standard accepted is 100mm; this makes the use of 10Base T-compatible tool with almost all phone line which are installed; this will reduce the cost of using coaxial cables that are used by the 10M-bps Ethernet.

We are talking about 10G and 100G networks now. Where do we go from here?

10G Ethernet

This refers to various technologies of Ethernet that is used in transmitting Ethernet wave at 10 gigabits per second. The 10G Ethernet supports the use of copper and fiber cabling and it defines full duplex point to point link which is connected to network switches. It contains different physical layer standards. 10G can be used in both LAN and WAN (wide area network) the 10G Ethernet can transmit up to 10 billion bits per second while 1G provides 1 billion bits per second.

100G Ethernet

This is a high speed networks which was established by IEEE (Institute of Electrical and Electronic Engineers), 100G transmits Ethernet wave at high speed compared to 10G. It transmits 100 Gbps (gigabits per second) over multiples of 10Gbs or 25 Gbs lanes. 100G is also used in LAN and WAN by providing high level transmission rate.

As technology advances the more need for a faster transmission of Ethernet waves is required hence the need of developing new and faster Ethernet technologies next on line after the 100G there is need to lay down structures that will enable to move from 100G to 400Gbps to 1 Tbps, this infrastructure include the one that will enable to move from 802.3 base to 802.11 base, since currently there is no TIA standards for 400Gbps or 1Tbps then there should be build on the current platform for multimode fiber, also there should be build up on parallel transmission of waves. By 2015, Terabit Ethernet is projected to be available for organizations to use and it is projected that new technologies like use of vacuum cored fibers may be used to handle the increasing demand of Ethernet for development.

Conclusion

There is need to move from the current 100G to either 400G or 1Tbps; this is because moving to high level/speed of transmission will help in reducing the cost of installation and operation of the Ethernet since there is already laid down infrastructures and what is needed is to invest on this infrastructure and improve on them to achieve the high speed required.
