We live in Network and are being fond of it.

An Ethernet is the entrance to Network World.

Once you put a RJ45 plug connector into your device.

I glad to tell you that...

“Welcome, you are connected with Network”

Thanks to Network,our life become more convenient.

And now, we communicate with Network every single day

It makes us so powerful to do everything immediately.

I can tell we kind of rely on this world and we love it.

Whether we only check an email, Facebook, or writing a NIKI entry

which is the moment we are in Network.

However, what kind of thing build up this world?

Ethernet is the technology build up this Network world step by step.

People often think Internet produce our Network.However, Internet just refers all human online activities.

Internet? My Answer is

Ethernet.

What is Ethernet?

Before I proceeding it, let’s see how it comes?

Ethernet employs the theory of communication practise.

In 1979, the employer of Xerox Corporation Bob Metcalfe invented the initial Ethernet by physically cabling the communication from his computers to a printer.

In other words, Ethernet is a station to assemble different mediums into one space where the mediums are connected.

Technically, the messages are shared between the mediums, and runs with the mode of Senfer-Meidum-Receivers (SMR).

Ethernet simply is a connection between two computers.

While a person use a transceiver to linearly connect two or more computer, this person can expand this size of Ethernet.

However, Linear connection seem redundant.So the engineers invent a medium called “Switch”

The Ethernet becomes more efficient as all computers are connected by switch

Computers can share information in a shortcut instead of lining.

40 years ago, neither the speed of Internet nor the extent of Internet is as advanced as modern time.

Ethernet as a necessary medium transmitting signalfrom sender medium to receivers medium.

40 years after, we still do the same thing. From you sending a Word document to a printer in a small Ethernet to you clicking on a hypertext in a large Ethernet, every step you’ve done is Ethernet communication.

Ethernet is evolving along with the industrial revolution…

From the initial 10Mbit/s to 10Gbit/s,

Ethernet is not only expanding the coverage of Network, But also offering a better and better online performance to users.

Now we can communicate with the world immediately!
