Ethernet Connection-how Does Ethernet Work?

Ethernet Connection

One or the other may have heard the term Ethernet before. Most, however, do not know what is behind it. Ethernet connection is by no means a new invention and is becoming increasingly important. Here we reveal what is behind the term and why it is so important.

What Is Ethernet?

Ethernet transport data from one device to another in a closed network . This   requires Ethernet-compatible devices and a connection between them. In this way, for example, photos can be sent from the computer to a  Smart TV  or documents can be sent from a PC to a printer, an external hard drive or another computer.

Necessary for this transfer and connection is an  Ethernet cable  – this is better under the term  LAN cable  known . The cable connect to a device and to the router. The router serves as an interface and connects the devices to a closed network. As a home network, this form is already relatively widespread. However, offices and companies knows it very well.

How Does Ethernet Work?

An Ethernet basically consists of two  component groups : the “Data Communication Equipment” ( DCE ) and the “Data Terminal Equipment” ( DTE ).

The data communication equipment includes all devices that can receive data and then forward it. For example router, hub and switch . They serve as interfaces and as a connection between the individual elements of the data terminal equipment. This is nothing more than the end devices that  receive the data from the DCE via the Ethernet  and can in turn  send them to other end devices via the  DCE.

What Is Ethernet Cable?

In order for an Ethernet to function and the data sent within a closed network, the data communication equipment must connect to the data terminal equipment using an appropriate cable . The correct name for this is Ethernet cable. However, most know it as  LAN cable  – with  Local  Area Network for “Local  area network is” or “local area network”.

The initial  Ethernets  were a thick coaxial cable. Therefore, the mold was initially called ” Thick referred Ethernet” (thick Ethernet). Over time, the cables became thinner and the shape was given a new name: ” Thin  Ethernet”. In the meantime, however, copper telephone cables have proven themselves as a transport medium for the data between distribution and end devices. For longer distances, however, cables made of  glass fiber  are used.

From the direct connection to the hub

During the early days of  Ethernet  , the computers were directly connected to  each other via a  cable harness . On the  one hand, this continuous  cable harness made it difficult to track down defects. This in turn could result in a  data congestion  and also made it more difficult to  restrict access  to data within the network .

Directional data transmission also reduces the risk of  data congestion  within the local network.

What Does Ethernet Do?

Advantages of the  Ethernet

Especially private users are mostly unfamiliar with Ethernet and may be wondering why it is not simply replaceing with a WLAN. After all, this is wireless and very easy to install. The Ethernet also has  some advantages over the WLAN (Wireless  Local Area Network).

including:

  • Independence: Whether the internet and  WiFi connection  is working or not, the technology  allows continuous data transmission. This makes it more reliable overall and is a good choice, especially in companies.
  • Security: since the Ethernet works  independently of the Internet and WLAN and is dependent on the connection via cable, it can be made more secure . Protection is easier with sensitive content within companies.
  • Cost-effective: The implementation of an  Ethernet  is extremely inexpensive compared to other systems.
  • Further development: Not least because of its numerous advantages and widespread use, the Ethernet is  developing continuously. This is also an advantage.

Disadvantages of the Ethernet

A potential disadvantage of  Ethernet  is that despite the control of the  data exchange  , collisions can still occur . As a result, the data transfer can be slow or limited.
