Ethernet is a communication protocol in a network by which computers and other network devices in a network are interconnected so that data can be exchanged. Ethernet technology is mostly used in Local Area Network (LAN). Ethernet technology is used to create networks at places like offices, schools, colleges etc.
Whenever a network is established, it needs a protocol to work. Protocols are rules made for the network, according to which devices in the network connect and share information. Ethernet is also a type of network protocol. Which is mainly used to build LAN networks.
In Ethernet technology, computers and other network devices are connected together with the help of cables, the cable used in this is called Ethernet cable. These cables are Coaxial Cables, Twisted Pair and Fiber Cables. Apart from Ethernet, LAN can be made in many different ways, which is called Topology. Like Bus, Star, Ring etc. Ethernet works at both the data link layer and the physical layer of the OSI network model. Technically we can define Ethernet as follows.
friends do you know What is Ethernet and its types? So friends today we will discuss this. But before that, let’s know some important things. It has been many years since the Internet came into our world and with it came various types of technology. One of those techniques is Ethernet. By the way, you would not know that wherever there is the internet, there is also Ethernet. You must know about LAN Local Area Network whenever there is a discussion about this network anywhere. You must have heard the name of Ethernet, so let’s learn something, new friends. what is ethernet and how it works?
What is Ethernet?
Ethernet To “ethernet “The treatment is done. This is a Local Area Network Technology. With the help of this technology, computers and networking devices are interconnected and information is shared.
Like in the office, in college, and in school. , Ethernet“TCP/IP is the protocol of the data link layer of the stack. With the help of this Ethernet technology, different computers in the LAN are able to share information among themselves.
This protocol means the work of Ethernet, in which format the information will be transmitted. As if he could transfer information from one computer to another in a LAN without any error.
Ethernet LAN It provides communication of information between networking devices. Let us take a simple example to explain this to you better. Like your computer LAB. Where Ethernet cable means all computers are interconnected only with the help of twisted pair cable.
But the information that reaches your computer with you, the name of that technology is Ethernet. Which is also called Ethernet protocol. By the way, you must know that there are 7 layers of the OSI Network Model, among them, the “Ethernet” data link layer and the “physical layer “Works in both.
Ethernet uses two types of units in data transmission, first Frame and second Packet. (Just like you weigh rice in packets, you weigh it in kilograms, and in tons, it passes through the network both in data frame and packet form),
The frame is not only taken with the payload but it is also taken along with the MAC address. MAC address is the address of the computer, such that it can receive the address of the Sender and Receiver computers.
History of Ethernet
Initially, Ethernet was called Alto Aloha Network. The name of the company that makes it is Xerox PARC. whom the sun 1973 I was invented by Robert Metcalfe together with some other people.
It was the first network to use CSMA/CD (Carrier Sense Multiple Access/ Collision Detection) technologies. Ethernet has been the fastest and most reliable network ever since. Which is still present everywhere. By 1980, it was being used in every corner of the world.
Ethernet used to run at a maximum speed of 10 Megabits per second in the beginning. After that, due to the changing technology, it started working at the speed of 100Mbps, which was called Fast Ethernet. Later 1000Mbps was called Gigabit Ethernet and now the speed is up to 10 Gigabit Ethernet.
Which is now the fastest of the door. Generally, the length of an Ethernet cable is 100 meters, but with the help of this cable, we can easily connect schools, colleges and offices.
What Components Are Required for an Ethernet Network
Now let us know which components are needed for the Ethernet network: –
- Ethernet Cable
- Ethernet HUB
- Crossover Cable
1) Ethernet Cable
With the help of an Ethernet cable, two or more computers can be connected together. Through which, data or information can come and go. Only one type of Ethernet cable is used in a LAN network. Examples of these cables such as twisted pair cables and fibre optics cables.
2) Ethernet HUB
It is a networking device through which we can connect the cables (wires) of all the computers. Hub connects all the computers in a network to Apsa. There are many Ethernet ports in a hub. In which these cables are connected.
3) Crossover Cable
We can use this cable in lieu of an Ethernet cable. It also has the same function, it is used when we connect two or more computers in apasa.
You must have heard its name whenever we talk about wifi networks. This word is definitely heard. The router is also a networking device through which the data coming from the network reaches the computer. And the data from the computer goes to the other network. These device Route means to determine the route. By now you know what Ethernet is. Now you will know how many types they are and what they are.
Advantages of Ethernet
There are many advantages of Ethernet such as –
- Ethernet speed is very high, 10 Gbps.
- Ethernet does not require a switch or hub.
- Ethernet is a very reliable technology.
- Maintaining Ethernet is very easy.
- Ethernet is a great technology for building small networks such as LANs.
- Security in Ethernet is of a very high level.
- The cost of Ethernet is also cheap.
Disadvantage of Ethernet
- Ethernet also has some disadvantages such as –
- Ethernet cannot be used to build large networks.
- Ethernet has limited mobility.
- It provides a nondeterministic service.
- Provides Ethernet Connection-less communication.
types of 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 easily install it. This is a Universal LAN network technology of all the 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 called IEEE Standard 802.3. Some rules were made in this standard so that all Ethernet networks can be easily configured. Along with this, with the help of this RULE, all the elements of this network can interact with each other. and be able to communicate.
2. Fast Ethernet
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 some minor changes were made in the Ethernet cable and Fast Ethernet was created.
Fast Ethernet throughput” videos, Multimedia, Graphics, InternetVery good in terms of. In this, the mechanism of error detection and correction has been used.
There are 3 types of Fast Ethernet: 100BASE-XT It is used with Level 5 UTP (Unshielded Twisted Pair) cable. 100BASE-FX is used with a fibre optics cable. 100BASE-T4 which uses 2 EXTRA wires. It is used with level 3 UTP. 100BASE-TX which is the very popular Fast Ethernet Standard.
If you want to configure 100BASE-T by changing the already existing 10BASE-T Ethernet. So you need to assess a few things. Like how many users are there, and what hardware is needed. Now if we talk further, Gigabit Ethernet is the next technology of the world. Which promises to give better data speed than Fast Ethernet.
So let’s know about it.
3. Gigabit Ethernet
Using Multimedia and Voice Over IP (VoIP) required a fast-running network. Gigabit Ethernet was created to achieve this speed. It is called “Ethernet-over-Copper” 1000BASE-T, 1000BASE-SX, 1000BASE-LX, and GigE is all examples of this. This is set out in the IEEE 802.3z Standard. In recent times, it works like a reed bone of many companies. It is 10 times faster than 100BASE-T,
We can put existing 10 and 100 Mbps cards in Gigabit Ethernet. With the help of this, we can interconnect switches, routers and servers and increase performance. If we look from the top layer of the data link layer, then Gigabit will look similar to other Ethernets.
And its implementation is also the same. The key difference between both Ethernets means fast and Gigabit is just this. Supports Gigabit Ethernet full duplex and the data rate is also very good.
4. 10 Gigabit Ethernet
This is the fastest and most modern Ethernet Standard Is. Which comes in IEEE 802.3ae version. Talking about its data transfer rate 10 Gbps Pay works. It is 10 times faster than the earlier Gigabit Ethernet.
Unlike other Ethernets, it works completely over an optical fibre cable connection. This is quite different from the standard LAN design as it transmits the data to all the nodes in the broadcast meaning. Till now it has not got the approval of the commercial standard. Because this is completely new. And by the way, its media type is given in the table below.
You can easily understand everything by looking at the table. Some information is given such as IEEE Standard, data rate, media type and maximum distance.

How Ethernet Works
If you have a little computer science knowledge, then you can easily understand this. But we understand it to you in simple language. As you know Ethernet is a LAN technology.
in which the data”packet and frame travels in the unit. It was also explained above that this CSMA/CD (Collision Sense Multiple Access/ Collision Detection) Uses a Mechanism.
With the help of CSMA/CD, whenever a computer in the Ethernet network sends a packet (data) to another computer. Then it senses 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 with which all the computers are connected). All the devices or computers in the network are connected to the destination address of that packet. Let’s check. And with whom he gets that address, he takes that packet.
If the main cable is busy then that computer waits till 1000 in 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 collision anywhere in the network.
So it detects it and shows it and tells it to the other device. By now you know what Ethernet is and how it works. But now let’s know a little bit about Ethernet cables.
Types of Ethernet Cable
By the way, here the Ethernet cable is given in the table below according to its category, cable type Maximum data transmission speed, and Maximum bandwidth. With that, you can easily understand everything.
Advantages of Ethernet
Now let’s know the Advantages of Ethernet What are:-
- Its speed is very fast. Normally its speed is 10 Gbps.
- Its cost (price) is also very low, that is, it is available cheap.
- it someone switch And the hub was not required.
- It is very reliable.
- Ethernet networks are easy to maintain and troubleshoot.
- It does not follow the client-server architecture so it has the same privileges as all the devices.
- There is no noise in the cable used in Ethernet, so the quality of the data transferred in it is very good.
- It has a high level of security. Therefore hackers cannot easily hack your information in this.
What is an Ethernet Port?
An Ethernet port can also be called a socket or a jack. the main function of an ethernet port make ethernet connections, Since its main purpose is to maintain connections, it is used to maintain Ethernet connections between computers, servers, switches, hubs, routers, modems, gaming consoles, printers, and more.
What is the main function of an Ethernet cable?
An Ethernet cable lets you physically connect your computer to the Internet.
what did you learn today?
So friends, today’s information is very important. If you are a student. Because this question comes in Computer Network What is Ethernet And how many types are there?
I would say this if you are running the Internet with the help of a LAN and Router, then all that we know about today is only his praise. One important thing if you buy a new computer, then you also get an Ethernet cable along with it. Everywhere in the world where there is a LAN, there is also Ethernet.
