Currently, being connected to the Internet is essential for almost all people, since we are all directly related to the Internet in some way, either for communicate, to inform us or to work. For this reason, over the years a great number of number of connection networks. Each of them with the purpose of providing a excellent service to its users.
Such is the case of ethernet, who has currently become one of the most popular forms of local area networkalso called wired LANs or the wide area network known as . Allowing connection to a large number of devicessuch as: printers, computers and all those servants for whom a connection to Internet.
In addition to that, ethernet networks have a technical profile IEEE 802.3 protocol. Profile that indicates how each of the devices it will be able to connect a Internet. And in turn, allows each of them to communicate with each other, through a common network language protocol. Therefore, below we are going to explain a little more about what they are ethernet networks Y How does this type of connection work?
What is an Ethernet connection and what is it for in computing?
Ethernet can be defined as one of the technologies that allows the connection of wired Local Area Networks, namely LANs and of WAN wide area networks. Also allowing each of the devices connected to it to communicate with each other, through protocols, which act as a common network language. Being a different alternative to that of , an alternative that has also turned out to be much more reliable and fasterbecause the device that the user uses will not have any kind of interference with other devices that are connected to the same network.
It has even been found that a ethernet networkis capable of currently connecting devices with speeds up to 100Gbit/s. and it is expected that in the not too distant future this speed increases to 400 Gbit/s.
But, Ethernet is not only responsible for connecting devices to the Internet. But also, it is used for connect a number of devices together. That is, with Ethernet users will be able to connect:
- Computers to computers.
- Computers to printers.
- Computers to speakers for video conferencing.
- Among many other devices that allow this type of connection.
Therefore, ethernet connections have also been considered as a local area network standard. Networks that are created through the union of multiple computers via cables.
Types of Ethernet Networks, which ones exist and how are they characterized?
Currently, there are at least 18 types of Ethernet networks. And each of them is differentiated by the type of wiring which is employed for the connection and of course with data transmission speed. However, within all these types of networks the most important and used are:
fast ethernet
This type of network is characterized mainly because it is capable of transmit data at a speed of 100 Mbps, all this through a cable or a twisted pair cable. And in addition to that, the data can be tranTransfer from 10 Mbps to 100 Mbps, all this without having to protocol translation and even without having to do any exchange rate in network software.
gigabit ethernet
This is one of the types of Ethernet cable most used today. since he is a guy ethernet network characterized by having the ability to transfer data at a speed of 1000 Mbps. And the same what FastEthernet, is a network based on twisted pair or fiber optic cable.
ethernet switch
When we talk about ethernet switchwe are referring to a network equipment that is needed to connect multiple network devices on a LAN. This type of network is characterized by using a instead of a crossed wire, as used in the other network types.
10Base2 Ethernet
Ethernet 10Base2, is characterized by using a thin coaxial cableit can fold easilyWhat is it cheaper and much easier to install. But this type of network has a detail. And it is that cable segments cannot exceed 200 meters and 30 nodes. Therefore, the vast majority of connections are made through tee connectors which are much safer and easier to install.
10Base5 Ethernet
This type of network uses a thick coaxial cableso it is also called coarse ethernet. Cable that also allows you Get speeds up to 10 Mbps. And since it is a cable with a large diameter, it can have a length of up to 500 meters and up to 100 nodes can be connected to it.
10Base-T Ethernet
This is the most common LAN today. And the cables used in this type of network they are twisted pair. In addition to this, each of its stations has a connection with a central and it is the system that managed to improve the defects of the 10BAse2 and 10Base5 networks. Since this type of network is able to detect the unwanted derivations, breaks and the presence of loose connectors. However, it presents two major disadvantages and these are: The cables have a length limit of 100 metersand that normally hubs are quite expensive.
Ethernet 10Base-FX
Ethernet 10Base-FX, is characterized by having very high speeds and for using optical fiber in order to connect the equipment. So it is usually an expensive type of network if what you want is a general approach of the entire network. But it is an ideal type of network to make all those connections that are required between buildings. Basically, because its segments allow lengths up to 2000 meters and being a fiber optic cablewill not be affected by noise or typical interference of those who normally suffer copper wires.
fast ethernet
This is a type of network that was created with the purpose of improve and smooth out the failures that present 10Base-T Ethernet networks. She is also known as 100BaseFx networks (IEEE 802.3u), and they are networks that seek to create alternatives for FDDI networks and are based on a star topology for optical fiber.
And for this type of network to be compatible with 10Base-T Ethernetits designers have ensured that Fast Ethernet technology preserve the formats of the packages and interfaces. But this type of network increases the speed of transmission at up to 100 Mbps. In addition to them, in this type of network cables of four twisted pairs of class 3. One of these wires goes directly to the central hub, another one leaves the hub, and the other two pairs of wires are switchable.
What are the protocols used in Ethernet networks and how do they work?
When we talk about protocols network, we refer to the formalisms that designate the entire set of rules that are in charge of regulating the exchange of information through one or several computer networks. And when we talk about Ethernet/IP we refer to a network protocol that is used to industrial automation applications and which is directly based on the , Some protocols that use the Ethernet hardware and software in order to establish a protocol level what to them allow you to configure, access and control all industrial automation devices.
From there then what Ethernet/IP is based on classifying the nodes according to the types of devices that are already established, we can then say that Ethernet/IP network protocol it is primarily based on the Control and Information Protocol over DeviceNet and ControlNet. That’s why Ethernet/IP is characterized by offering complete integrated system, which goes from the industrial plant to the central network of the company. And within the protocols ethernet the most used are:
TCPIP transport protocols
This is a protocol that was developed over the course of the Cold Warsince it was thought about the possibility that the enemy could attack and destroy any of the nerve centers of the main command networks. And it was not enough to place many command centersbecause well everyone could be attacked and destroyed.
So the solution that was achieved was that there was basically no physical command center, making it possible for any node to become one. From there then came the tcpip protocol, a network among equals, which would adapt to the Conditions like this would destroy half the country. And it was such a good design that even today it works like a charm with the modern internet. Plus this new Protocol, fits perfectly to the new WAN modelwho was born at that time.
So in a few years TCPIP, was in charge of disappearing from the market the other existing protocols and offers. So much so that today it is the indisputable communication standard in the LAN and WAN networks. As TCPIP comes from Transport Control Protocol / Internet Protocoland is characterized by being made up of two parts, the first of which is the transport protocol or TCP and the second the Internet Protocol or IP. That is, in TCPIP one of these parts is in charge of the transport and the other part that is in charge of giving meaning to the data that is received.
CSMA/CD
Carrier Sense Multiple Access with Collision Detection or in Spanish multiple access with carrier listening and collision detection. It is a shared media access algorithm that is characterized by having a multiple access, detect collisions, have carrier sense, jam signal and random backoff, it also has hubs and collision domain.
CSMA/CA
It is a protocol low-level network access control which allows multiple stations to use the same source of transmission. And its acronym in Spanish means multiple access with carrier eavesdropping and collision avoidance.
It is characterized because the station monitors the channel before starting the transmission, in addition to this, it is also in charge of monitoring all its transmission to always be sure that another station will not interrupt the busy trunkin order to avoid a collision. Since if a data collision occurs, it will be necessary for the station to transmit a busy signal, in order to transmit its communication.
Advantages and Disadvantages of Ethernet Is it the fastest and most secure connection?
ethernetis currently one of theThe fastest and most secure connection networks that exists, however it has its advantages and disadvantages. That is why we will talk a little about both.
Advantages of Ethernet network connection
Among the main advantages of the Ethernet connection are:
- It has a better use of .
- As already mentioned aboveconnection speed with the router it is much faster. well today ethernet connections standard they are usually at least 1 Gbps.
- By having the connection through a network wire, the bandwidth it will be much better. since when Wi-Fi is used the equipment will have losses as we move away from the router or change rooms.
- The ethernet cable connection It is also characterized by being much faster for…
