What is Ethernet - Definition and Explanation

Internet has been in our world for a long time and with it a lot of technology has come, one of them is Ethernet, you hardly know that wherever there is Internet, Ethernet is also available on your LAN (Local Area Network), you must have heard about Ethernet's name whenever it comes to this network. So are you excited ? Let's see What is Ethernet.

Ethernet is a technology commonly used in the Wide Local Area Network (LAN) A network of LAN computers and other electronic devices that cover a small area such as a home, office, building. Ethernet is a network protocol that controls how to transfer data over a LAN. Technically it is known as the IEEE 802.3 protocol.

What is Ethernet?

Ethernet is pronounced with Ether + Net. It is a Local Area Network Technology. With the help of this technology, computers and Networking devices are connected and information is shared with the help of this Ethernet Technology. - Different computers are able to share information among themselves.

What is Ethernet - Definition and Explanation

This kind of work is the work of Ethernet Protocol like- Information will be transmitted in which format so that it can transfer information from one LAN to other computers without any error. 

Ethernet LAN provides information sharing between the Networking Devices.

In Ethernet Technology you connect computers with the help of Cables, at first Ethernet Technology used Coaxial Cables but now Twisted Pair and Fiber Cables are also used in it. 

With Ethernet Technology LAN can be created in many ways called Topology like Bus, Star, Ring and Mesh Topology etc.

How Ethernet Works?

Ethernet Cable is used to setup LAN. It covers very low area such as for a home, school, or office etc. When one machine wants to send data to another machine through network. 

First of all, the data packet finds the sender so that they can find out how many Wire Computers are connected to the network, 

Then it finds out that none of them already have the data packet available, and checks that The way to send data is clear So Mr. Not all machine Free someone can Data Send to a machine Network.

Then it starts checking where to get all the machine data connected to the computer network and then that packet or data is retrieved where it has to be received, some times it happens that send a machine data Does. 

But if other machines are busy in receiving another data packet, then in such a time the data packet sent from one machine waits for some time and when that machine becomes free, then that data packet is sent back to that machine. Goes so that he can receive it.

Types of Ethernet Network

There are many types of Ethernet Network, let's know about them.

Fast Ethernet

This is a type of Ethernet Network that performs data transfer at speeds ranging from 10 Mbps to 100 Mbps with the help of Twisted-pair Cable and Fiber Optic Cable and Ethernet to transmit data at a speed of 10 Mbps. 

But it does not know how to provide Necessary Bandwidth for Video Application. And while the older version Ethernet Version is still used.

Ethernet Standard is called IEEE Standard 802.3 and its Extended Version Fast Ethernet has come. It is called IEEE Standard 802.3U. 

Fast Ethernet is designed for higher Transmission Speed. It is very good in Throughput Video, Multimedia, Graphics, Internet Surfing There are three types.

What is Ethernet - Definition and Explanation

100BASE - TX It is used with Level 5 Unshielded Twisted-pair Cable.
100BASE - FX It is used with Fiber-optic Cable.
100BASE - T4 uses it for Level 3 Unshielded Twisted-pair Cable and two viruses.


Gigabit Ethernet

This is a type of Ethernet Network that is suitable for transferring data at a speed of 1000 Mbps with the help of Twisted-pair Cable and Fiber Optic Cable and is the most popular network. 

It has been developed to work very quickly with applications like Multimedia and Voice Over IP and is also known as 1000 BASE-T. Twisted-pair cable is Cat-5E Cable supporting Gigabit Ethernet.


10 Gigabit Ethernet

10 Gigabit Ethernet is the newest generation of Ethernet that is capable of transferring data up to 10 GBPS (10,000 Mbps) using Twisted-pair Cable and Fiber Optic Cable. 

IEEE Standard defines a version of 802.3ae Ethernet and it Gigabit 10 times Faster than Ethernet. 10GBASE - LX4, 10GBASE - Er, 10GBASE - SR used to add distances up to 10,000 meters based on optical fiber Vable.


Difference Between Internet And Ethernet

Now we will tell you what is the difference between Internet and Ethernet.



The Internet is a global system that connects devices around the world, for which it uses TCP / IP Protocol. 

Ethernet is a Networking technology used in Local Area Network (LAN) through a single location But computers are connected to each other.


Network Type

The Internet is a Wide Area Network while Ethernet is a Local Area Network. The Internet is spread across the world and Ethernet is located in just one place.



Ethernet provides more security than Internet. No other network can be accessed in Ethernet, whereas in the Internet, the user has an open exemption, that is why any user can go to the network and get information about their work.


What is Ethernet Cable?

Three Cables are mainly used in Ethernet Technology.


Coaxial cable

This kind of cable has a Signal Wire which is surrounded by the shell of the Insulator, Metal Shield and Plastic. The Insulator controls the Signal and protects the Metal Shield from Electromagnetic Interference because the Signal cannot be destroyed in the middle and the Plastic can Protects from water and fire outside. Know about its version.

Twisted-pair cable

This type of cable is most commonly used in Ethernet Technology. Twisted-pair cable consists of 2 or 4 pairs of copper wires surrounded by plastic shells and wrapped together to prevent cross talk when using a wire. 

Signal deteriorates the Signal of the other wire, it is called Cross Talk. Learn about its version.


Some of the categories of twisted-pair cable which are as follows.

Cat - 3
Cat - 5
Cat - 5E
Cat - 6


Fiber Optic Cable

Coaxial Cable and Twisted-pair Cable carry their data with the help of Electronic Signal but Fiber Optic Cable carries their data with the help of Light Fiber Optic Cable consists of wires like thin threads which are made of Plastic or Glass Occur.  

Bandwidth of this cable is more than that of other metal cable and this cable carries more data than other cables, its signal is much less bad and it is thinner and lighter than other cable. Know about Versions of Fiber Optic Cable.

    Single Mode Fiber

    Multi Mode Fiber

This is a Local Area Network Technology. With the help of this technology, computers and Networking Devices are connected to each other and information is shared more. 

Like in office, in college, in school there is excess. "Ethernet" is the protocol of the data link layer of TCP / IP Stack. As such, they could access information in a LAN from good to other computer without any error.

What is Ethernet - Definition and Explanation

Ethernet communicates information between Networking devices in LAN. To explain this to you in good way, take an example. Like your computer LAB. 

Where Ethernet cable means all computers are connected with the help of twisted pair cable. But the information that you have till your computer, the name of that technology is Ethernet. Which is also called Ethernet protocol. 

By the way, you will know that there are 7 layers of OSI Network Model, out of which "Ethernet" works in both the data link layer and the "physical layer".

Ethernet uses two types of units in data transmission, first frame and second packet (as you weigh rice in packet, you weigh it in kilograms, and also in tons, similarly the network in both data frame and packet. passes by). 

Frame does not just take Payload but it also takes MAC Address too. MAC address is the address of the computer, such that it can get the address of Sender and Receiver Computers.


History of Ethernet 

In Alwar, Alto Aloha Network spoke highly to Ethernet. This was the first network that used CSMA / CD (Carrier Sense Multiple Access / Collision Detection) technology. 

Ethernet has been the fastest and reliable network ever since. Which is still available everywhere. By 1980, it was used in every corner of the world.

The Ethernet used to run at a speed of maximum 10 Mega bits per second in past some years. 

After that due to changing technology, it started working at a speed of 100Mbps, which was called Fast Ethernet. 

Later 1000Mbps which was called gigabit Ethernet and now speeds up to 10 gigabit Ethernet.


What Component is required for Ethernet Network

Ethernet Cable
Ethernet HUB
Crossover cable


1) Ethernet Cable

With the help of Ethernet cable, two or more computers can be connected together. Through which data or information can be known. 

The same type of Ethernet cable is used in a LAN network. Examples of these cables such as twisted pair cable and fiber optics cable.


2) Ethernet HUB

This is a Networking device through which we can connect the cables of all computers. Hub connects all computers in a network to Upsa. 

There are many Ethernet ports in a hub. In which these cables are connected.


3) Crossover Cable

We can use this cable instead of Ethernet cable. It also has the same function, when we connect two or more computers to Apasa, it is used.


4) Router

This Sabbath is definitely heard. Router is also a networking device through which the data computer coming from the network is accessible. 

And the data from the computer runs in another network. This device Route determines the way. By now you know what Ethernet is. Now you will know what are these types and what are they.

What is Ethernet - Definition and Explanation

Types of Ethernet network

1. Ethernet

You have come to know that Ethernet is a LAN Technology. A Standard Ethernet network works at 10 megabits per second. 

The performance of this technology is quite good because it is cheap and gives high speed data transmission. 

We can install it easily. It is a universal LAN network technology of all computers in the world. 10BASE-T is an example of this Ethernet technology. It supports all protocols, so it is special.

The Institute for Electrical and Electric Engineering created an Ethernet Standard (standard) called IEEE Standard 802.3. 

With this, with the help of this RULE, all the elements of this network can interact with each other. And could communicate.


2. Fast Ethernent

Gradually, the next standard of Ethernet emerged. Which was called Ethernet Standard IEEE 802.3u. Its transmission speed is around 10 Mbps to 100 Mbps. 

Just a few tweaks were made to the Ethernet cable and Fast Ethernet was made. fast Ethernet's throughput is very good in terms of "videos, multimedia, graphics, internet". 

The mechanism of error detection and correctoin has been used in this.

By the way, there are 3 types of Fast Ethernet: 100BASE-XT used with Level 5 UTP (Unshielded Twisted Pair) cable. 100BASE-FX is used with fiber optics cable. 100BASE-T4 which uses 2 EXTRA wire. It is used with level 3 UTP.

If you already want to configure 100BASE-T by making changes to existing 10BASE-T Ethernet. So it is very important to assess some things. Like how many users are there, and what hardware is required.


3. Gigabit Ethernet

A fast running network was needed to use Multimedia and Voice Over IP (VoIP). Gigabit Ethernet was created to achieve this speed.

It is defined in the IEEE 802.3z Standard. In Phil Hall, it works like a reed key for the whole company. It is 10 times faster than 100BASE-T.

With the help of which we can interconnect switches, routers and servers and increase performance.And its implementation is also the same. Gigabit supports Ethernet full duplex and data rate is also quite good.


4. 10 Gigabit Ethernet

This comes in the IEEE 802.3ae version. Talking about its data transfer rate, it works at 10 Gbps. It is 10 times faster than the earlier gigabit Ethernet.

What is Ethernet - Definition and Explanation

Unlike other Ethernet, it works completely on optical fiber cable connection. This is quite different from the standard LAN design because it broadcasts data across all nodes. It has not yet received the approval of the Commercial Standard. Because it is all new.


How Ethernet Works

If you have a little knowledge of computer science, then you can understand it very easily. But we understand this in simple language. 

As you know Ethernet is a LAN technology. In which data travels in the unit of "packet and frame". 

It was also explained above that it uses the CSMA / CD (Collision Sense Multiple Access / Collision Detection) mechanism.

Whenever a computer in Ethernet network sends packet (data) to another computer with the help of CSMA / CD. 

Then it makes sense to the main cable (whether there is already a packet in the main cable). If there is no packet in the wire, then Ethernet sends the packet to the main wire. 

(The main wire is the same one with which all the computers are connected) All the devices in the network or the computer is connected to the destination address of that packet. Let's check.

If the main cable is connected, then it waits for 1000 hours in Computer 1 second and whenever the main cable is free, it sends it back to the Packet. 

CD means with the help of Collision Detection if there is any conflict anywhere in the network. So it looks it by detecting it and tells the other device. By now you know what Ethernet is and how it works.
