Friends, do you know what is Ethernet and its variants. So friends, we will discuss about it today. But before that, we know some important things. Internet has been in our world for many years and with it came a variety of technology. One of them is Ethernet. By the way, you will not know that wherever there is internet, there is also Ethernet. You will know about the LAN Local Area Network whenever there is a discussion about this network. You must have heard the name of Ethernet, so friends, let’s learn something new, what Ethernet is and how it works.
What is Ethernet ?
Ethernet is borrowed as ” ether net “. 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. Like in office, in college, in school there is excess. ” Ethernet ” is the protocol of the data link layer of TCP / IP Stack . With the help of this Ethernet Technology, different computers in LAN are able to share information among themselves. This protocol means the work of Ethernet, information in which format will be transmitted. As such, they could access information in a LAN from good to other computer without any error.
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 both in data frame and packet. Is passing through) . 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. The name of the company making it is Xerox PARC. Which was met by Robert Metcalfe in 1973 to meet some other people. 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 the speed of maximum 10 Mega bits per second in Surawati Dor. After that due to the 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. Which is now the fastest of Dor. Generally, the length of Ethernet cable would be 100 meters, but with the help of this cable we can easily connect school, college and office.
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.
You must have heard its name whenever we talk about wifi network. 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.
Types of Ethernet network
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. In this standard, some rules have been made so that all Ethernet networks can be easily configured. 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. 100BASE-TX which is very popular dear Fast Ethernet Standard.
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. Now, if we talk further, Gigabit Ethernet is the next technology. Which promises to provide better data speed than Fast Ethernet. So let’s know about this.
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. These are examples of “Ethernet-over-Copper” 1000BASE-T, 1000BASE-SX, 1000BASE-LX, and GigE. 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.
We can put Mojuda 10 and 100 Mbps cards in Gigabit Ethernet. With the help of which we can interconnect switches, routers and servers and increase performance. If we see from the top layer of data link layer, then Gigabit will look similar to other Ethernet. And its implementation is also the same. The significant difference between both Ethernet means fast and Gigabit is just that. Gigabit supports Ethernet full duplex and data rate is also quite good.
4. 10 Gigabit Ethernet
This is the fastest and most modern Ethernet Standard . Which 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.
Unlike other Ethernet, it works completely on optical fiber cable connection. This is quite different from the standard LAN design as it broadcasts data across all nodes. It has not yet received commercial standard approval. Because it is all 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 such as IEEE Standard, Data Rate, Media Type and Maximum Distance is given.
How Ethernet Works
If you have some knowledge of computer science, then you can understand this 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 (do you know if 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. And with whom he gets the address, he takes that packet.
If the main cable is connected, then that computer waits for 1000 to 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 interference anywhere in the network. So it looks by detecting it and tells the other device. By now you know what Ethernet is and how it works. But now a few people know about Ethernet cable.
Types of Ethernet Cable
By the way, here on Ethernet cable , according to the category, cable type and Maximum data transmission speed, Maximum bandwidth , its type is given in the table below. With this you can easily understand everything.
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 will say the same if you are running the Internet with the help of LAN and Router, then all that we know about today is its own right. One important thing if you buy a new computer, then you also get Ethernet cable together. Everywhere in the world where there is a LAN there is also Ethernet.
