What is Ethernet? Advantages and Disadvantages of Ethernet?
Guys do you know what is Ethernet (What is Ethernet in Hindi) and its types. So guys today we will discuss about this. But before that, let us know some important things. The Internet has been in our world for many years and with it came various technologies. One of them is Technology Ethernet. By the way, you may not know that wherever there is internet, there is also Ethernet. You must know about LAN Local Area Network whenever there is any discussion about this network. You must have heard the name Ethernet, so let’s learn something new, what is Ethernet and how it works.
What is Ethernet
Ethernet is pronounced “ether net”. This is a Local Area Network Technology. With the help of this technology, computers and networking devices are connected and information is shared. As is done in office, in college, in school. “Ethernet” is the protocol of data link layer of TCP / IP Stack. With the help of this Ethernet technology different computers in LAN are able to share information with each other. This protocol means the work of Ethernet, in what format the information will be transmitted. As if he could transfer information from one LAN to another computer without any error.
Ethernet communicates information between Networking devices in LAN. Let us take an easy example to explain this to you. Like your Computer LAB. Where Ethernet cable means twisted pair cable, all computers are connected to each other. But the information that you have on your computer is called Ethernet. Also called Ethernet protocol. By the way you must know that OSI Network Model has 7 layers out of which “Ethernet” works in both data link layer and “physical layer”.
Ethernet uses two types of units in data transmission, first frame and second packet (just like you weigh rice in packet, you weigh it in kilograms, and also in ton. Passes through). Frame not only carries Payload but also carries MAC Address along. MAC address is the address of the computer, so that it can get the address of the sender and receiver computers.
History of Ethernet
Initially, Ethernet was called Alto Aloha Network. The company that makes it is called Xerox PARC. Which was invented by Robert Metcalfe in 1973, along with a few others. It was the first network to use CSMA / CD (Carrier Sense Multiple Access / Collision Detection) technology. 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 globe.
Ethernet initially ran at a maximum speed of 10 Mega bits per second. 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 the speed is up to 10 gigabit Ethernet. Which is now the fastest of the two. Normally the length of Ethernet cable is 100 meters but with the help of this cable we can easily connect school, college and office.
Which component is required for Ethernet Network?
- Ethernet Cable
- Ethernet HUB
- Crossover Cable
Types of Ethernet network
As you may know, Ethernet is a LAN technology. A standard Ethernet network operates at 10 megabits per second. The performance of this technology is quite good as it is cheap and gives high speed data transmission. We can easily install it. This is a Universal LAN network technology for computers all over 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 developed an Ethernet Standard called the IEEE Standard 802.3. Some rules have been made in this standard so that the entire Ethernet network can be easily configured. At the same time, with the help of this RULE, all the elements of this network can interact with each other. And communicate.
- Fast Ethernent:
Gradually the next standard of Ethernet emerged. Spoken Ethernet Standard IEEE 802.3u. Its transmission speed is around 10 Mbps to 100 Mbps. The Ethernet cable was modified and Fast Ethernet was created. Fast Ethernet throughput is great in terms of “videos, multimedia, graphics, internet”. It uses error detection and correctoin mechanism.
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 fiber optics cable. 100BASE-T4 which uses 2 EXTRA wire. It is used with level 3 UTP. 100BASE-TX which is very popular Fast Ethernet Standard.
If you want to configure 100BASE-T by modifying the existing 10BASE-T Ethernet. So it is very important for you to assess some things. Like how many users are there, and what hardware is needed. Now let’s talk about Gigabit Ethernet which is the next technology of the future. Which promises better data speed than Fast Ethernet. So let us know about it.
- Gigabit Ethernet:
Using Multimedia and Voice Over IP (VoIP) required a fast running network. Gigabit Ethernet was built to achieve this speed. Its “Ethernet-over-Copper” 1000BASE-T, 1000BASE-SX, 1000BASE-LX, and GigE are all examples. It is set in the IEEE 802.3z Standard. Phil recently acted as the reed bone of many companies. It is 10 times faster than 100BASE-T.
We can insert existing 10 and 100 Mbps cards into Gigabit Ethernet. With the help of which we can interconnect switches, routers and servers and increase performance. From the top layer of the data link layer, if we look, Gigabit will look the same as the other Ethernet. And so is its implementation. This is the important difference between both Ethernet fast and Gigabit. Gigabit Ethernet supports full duplex and the data rate is also quite good.
- 10 Gigabit Ethernet:
This is the fastest and most advanced Ethernet Standard. Which comes in IEEE 802.3ae version. Talking about its data transfer rate, it works at 10 Gbps. It is 10 times faster than the previous gigabit Ethernet.
Unlike other Ethernet, it works entirely on optical fiber cable connection. This is quite different from the standard LAN design as it transmits data across all nodes. So far it has not received commercial standard approval. Because it’s brand 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 of the information given is IEEE Standard, data rate, Media type and Maximum Distance.
How Ethernet Works
If you have some knowledge of computer science then you can easily understand this. But we understand it in simple language. As you know Ethernet is a LAN technology. In which the data travels in the unit of “packet and frame”. It was also explained above that it uses CSMA / CD (Collision Sense Multiple Access / Collision Detection) mechanism.
With the help of CSMA / CD whenever one computer in Ethernet network sends packet (data) to another computer. It then senses the main cable (does the address already have 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 one with which all the computers are connected) Let’s check. And the one with whom that address is found takes that packet.
If the main cable is busy then the computer waits for 1000 parts of 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 detects it and tells the other device. By now you know what Ethernet is and how it works. But now let’s learn a little bit about Ethernet cable.
Types of Cable
By the way here Ethernet cable is given below category, cable type and Maximum data transmission speed, its type according to Maximum bandwidth in the table below. With that you can easily understand everything.
- The quickest speed give by Gigabit ethernet is of 1Gbps. The speed goes from in excess of multiple times Fast Ethernet.
- To frame an Ethernet, we needn’t bother with much expense. It is generally cheap. Complete expense actuated is less.
- In Ethernet, all the hub have a comparable honors. It doesn’t follow customer server engineering.
- It doesn’t need any switches or centers
- Upkeep and organization are straightforward.
- The link wont to interface frameworks in ethernet is solid to commotion.
- As it is solid to the commotion, the norm of the information move doesn’t corrupt. The information move quality is great.
- With most recent forms like gigabit ethernet and remote ethernet (IEEE 802.11ac/11ad) move speeds in information with the speed of 1-100Gbps.
- It offers a nondeterministic administration.
- It doesn’t hold great for ongoing applications since it requires deterministic assistance.
- As need parcels can’t be set, it’s not reasonable for a customer server design.
- In an intelligent application, information is tiny and wish speedy information move. In ethernet, there’s a constraint of the base size of the casing to 46B. Subsequently, it’s anything but a genuine decision for intuitive applications.
- On the off chance that you’re involving it for intuitive applications, you must take care of faker information to shape the casing size 46B which is required.
- Not appropriate for traffic-escalated applications. On the off chance that the pace of traffic on the Ethernet goes up the productivity of the Ethernet goes down.
- It gives connectionless correspondence over the organization.
- The recipient can’t ready to send any information in the wake of getting the parcels.
- Assuming there’s any issue in ethernet, it’s hard to investigate what link or hub inside the organization causing a real issue.
- The 100Base-T4 form doesn’t uphold full-duplex information correspondence mode.
