What is Ethernet and its history?
Do you know friends what is Ethernet ) and its types. So friends, today we are going to discuss this. But before that let us know some important things. It has been many years since the Internet entered our world and with it different types of technology emerged, one of which is Ethernet. By the way, you will not know that wherever there is Internet, there is also Ethernet. You must know about the local LAN whenever there is a discussion about this network anywhere. You must have heard the name Ethernet, so let’s learn something new friends. What is ethernet and how does it work.
What is Ethernet
Ethernet for the ” Ethernet network ” has been treated. This is a local area network technology. With the help of this technology, computers and networking devices are linked together and information is shared. It also happens in the office, in college, at school. And Ethernet “TCP/IP is the data link layer protocol of the stack. With the help of this Ethernet technology, different computers in the local network are able to share information among themselves. This protocol means Ethernet work, where the information will be sent in a format. As if it could get the information from One computer to another in the LAN without any error.
Ethernet LAN provides information communication between network devices. Let’s take a simple example to better explain this to you. Like your LAB computer. Whereas, Ethernet cable means that all computers are connected to each other only with the help of twisted pair cable. But the information you have arrives on your computer, and the name of that technology is Ethernet. Which is also called the Ethernet protocol. By the way, you should know that there are 7 layers of the OSI network model, of which the “Ethernet” data link layer and the ” physical layer ” runs on both.
Ethernet uses two types of modules to transmit data, first frame and second packet. (Just as you weigh rice in packets, you weigh it in kilograms and also in tons, likewise it passes through the network in both data frame and packet form) The frame is not only captured with Payload, but also taken with the MAC address. The MAC address is the address of the computer, so that it can receive the address of the sending and receiving devices.
Ethernet history
Initially, Ethernet was called the Alto Aloha network. The name of the company that makes it is Xerox PARC. From the Sun 1973 Robert Metcalfe invented me along with some other people. This was the first network to use CSMA/CD (Carrier Sensor Multiple Access/Collision Detection) technology. Ethernet has been the fastest and most reliable network ever since. which is ubiquitous until now. By 1980, it was used in every corner of the world.
It uses Ethernet to run at a maximum speed of 10 Mbps initially. Then, due to changing technology, it started running at 100Mbps, which is what I call Fast Ethernet. Later 1000 Mbps which was called Gigabit Ethernet and now the speed is up to 10 Gigabit Ethernet. He is now the fastest in the door. In general, the length of the Ethernet cable is 100 meters, but with the help of this cable we can easily connect school, college and office.
What components are required for an Ethernet network?
- Ethernet cable
- Ethernet hub
- crossover cable
- Router
1) Ethernet cable
With the help of an Ethernet cable, two or more computers can be connected together. Through them data or information can come and go. Only one type of Ethernet cable is used in a LAN. Examples of such cables are twisted-pair cable and optical fiber cable.
2) Ethernet hub
This is a network device with which we can connect cables (wires) to all computers. The Hub connects all the computers in the network to the Apsa. There are many Ethernet ports in the hub. to which these cables are connected.
3) Crossover cable
We can use this cable instead of Ethernet cable. It also has the same work, when we connect two or more computers in apasa, it is used.
4) router
You must have heard her name whenever we talk about wifi. This word is definitely audible. A router is also a network device through which data from the network reaches the computer. The data is transmitted from the computer to the other network. This device path means that it defines the path. Now you know what Ethernet is. Now you will know how many types and what they are.
Types of Ethernet networks
1. Ethernet
You have come to know that Ethernet is a LAN technology. Standard Ethernet operates at a speed of 10 megabits per second. The performance of this technology is very good because it is cheap and provides high data transfer speed. We can install it easily. This is a universal LAN technology for all computers in the world. 10BASE-T is an example of this Ethernet technology. It supports all protocols, so it’s private.
The Institute of Electrical and Electrical Engineering created an Ethernet standard called IEEE Standard 802.3. Some rules are made in this standard so that all Ethernet networks can be easily configured. Besides, 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
The next standard for Ethernet gradually emerged. Which was called Ethernet Standard IEEE 802.3u. Its transmission speed is around 10Mbps to 100Mbps. Some minor changes were made to the Ethernet cable and Fast Ethernet was created. Very good fast Ethernet transfer speed in the case of “videos, multimedia, graphics and the Internet”. In this error detection and correction mechanism was 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 fiber optic cable. 100BASE-T4 which uses two extra wires. It is used with Level 3 UTP. 100BASE-TX is a very popular Fast Ethernet standard.
If you want to configure 100BASE-T by changing the already existing 10BASE-T Ethernet. So it is very important for you to evaluate a few things. Like how many users and what devices are required. Now if we talk more, Gigabit Ethernet is the next technology in the world. Which promises to deliver better data speed than Fast Ethernet. So let’s know about her.
3. Gigabit Ethernet
To use Multimedia and Voice over IP (VoIP), a fast running network is required. Gigabit Ethernet was built to achieve this speed. 1000BASE-T, 1000BASE-SX, 1000BASE-LX, and GigE are examples. This is specified in the IEEE 802.3z standard. Recently, he works like a cane bone in many companies. It is 10 times faster than 100BASE-T.
We can put 10 and 100 Mbps cards in Gigabit Ethernet. With the help of which we can connect switches, routers, servers and increase performance. If we look from the top layer of the data link layer, Gigabit will look similar to other Ethernet. And its implementation is the same. The important difference between Ethernet means speed and Gigabit is just this. It supports full-duplex Gigabit Ethernet and the data rate is also very good.
4. 10 Gigabit Ethernet
This is the fastest and most modern Ethernet standard to be. Which comes in IEEE 802.3ae version. Talking about a data transfer rate of 10 Gbps Pay works. It is 10 times faster than the previous Gigabit Ethernet.
Unlike other Ethernet, it is fully functional over optical fiber cable connection. This is quite different from the standard LAN design as it transmits data to all nodes in the sense of broadcasting. So far the commercial standard has not been approved. Because this is completely new. And by the way, its media type is shown 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 provided.
How does Ethernet work
If you have some knowledge of computer science, you can understand it easily. But we understand you in simple language. As you know, Ethernet is a LAN technology. where the data ” packet and frame travels in unit”. It has also been explained above that this CSMA/CD (Multiple Collision Sensing/Collision Detection) mechanism uses.
With the help of CSMA/CD, when a computer in an Ethernet network sends a packet (data) to another computer. Then it senses the main cable (know if there is already a beam in the main cable). If there is no packet in the wire, Ethernet sends the packet to the main wire. (The main wire is the same that all computers are connected to.) All devices or computers in the network are connected to the destination address of that packet. Let’s check. And with whoever gets that address, he takes that package.
If the main cable is busy, this computer waits up to 1000 for 1 second, and whenever the main cable is empty, 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 detects it and tells it to the other device. Now you know what Ethernet is and how it works. But now let’s know a little about Ethernet cable.
Ethernet cable types
By the way, the Ethernet cable is presented in the table below according to its class, type of cable, maximum data transfer speed, maximum bandwidth. With it you can easily understand everything.
my last word
Friends, today’s information is very important. If you are a student. Because this question comes up in computer network What is Ethernet and how many types are there? I would say this, if you still operate the Internet with the help of LAN and Router, then all we know today is its own glory. An important thing if you buy a new computer, you will also get an Ethernet cable with it. Everywhere in the world where there is LAN, there is also Ethernet. If you want to ask any question now, definitely write in the comment box below. And if you want to make any suggestion, you should definitely give it a go so we can do something new.
