Ethernet: everything you need to know about the wired network –

Ethernet is the network we use when we connect to the Internet through a wired connection. It is more suitable for local connections as it greatly reduces latency issues and increases the level of security.

If the Wi-Fi network is more widespread these days, it is above all because of its great coverage and its practicality. Only, before that, we used a wired connection: Ethernet. Used for more than half a century, the wired network is not about to disappear. Even today, many organizations prefer to use it over Wi-Fi, as it allows many tasks to be carried out at the same time and make the most intensive. In this file we will detail what Ethernet is, its use, its advantages and possibly its disadvantages. We will not stop doing a little comparative analysis between Ethernet and Wi-Fi.

What is Ethernet?

Ethernet is a communication technology used to access the Internet through the local LAN network. This involves the use of an Ethernet cable to connect the PC to the network router. Technicians also call it IEEE802.3.

During its early years of use, Ethernet operated at speeds significantly less than 10 Mbps. Over the years, experts have made changes and improvements to it. As a result, most connections today run at gigabit speeds. Some ratified standards can even reach gigabit speeds, ranging up to 400Gbps.

In addition to the wired LAN connection LANalso allows devices to connect over a wide area network WAN. Devices can also communicate with each other over this wired network and transfer data. The Ethernet connection is found in various establishments (schools, shops, etc.) due to its great capacity to withstand network disturbances and its higher speed.

The different types of Ethernet

The technology was conceived in 1973. However, its public debut was not registered until a decade later, that is, in 1983, the year of its approval. Since then, Ethernet has gone through different iterations until 2022 when we decided to formalize the three most used types. These are Fast Ethernet, Gigabit Ethernet, and 10 Gigabit Ethernet.

Although his name means fast, fast ethernet it is far from offering the highest speed of the three types. In general, the connection speed is limited to 100 Mbps. Instead, gigabit-ethernet it can provide speed up to 10Gbps. As to 10-Gigabit Ethernet, is the wired connection that provides ultra-fast speed, ranging from 40GbE to 400GbE. These are used by data centers, internet service providers, and other organizations that require high-speed data transmission.

Who uses Ethernet? Why ?

Ethernet is the most popular form of network connection. It is particularly used by schools, hospitals and certain companies. This wired network is used rather for its security and the baud rate of the data you provide. That is why it is found in data centers and ISPs.

At the time it started appearing on the market, Ethernet was less expensive compared to its competitors. Nowadays, streaming and gaming fans should opt for Ethernet network instead of Wi-Fi as it provides a stable connection and reduces latency.

Since its inception in the mid-1990s, the IEEE or Institute of Electrical and Electronics Engineers has been regularly updated to increase its performance. That is why it finds its place both in the productive environment and at home.

The benefits of Ethernet

Ethernet offers a number of advantages, which is why it remains so popular. The use of the cable to transfer data is an irreproachable asset for its reliability. This removes the network interference as well as physical barriers. Also, it provides a faster connection.

Also, Ethernet is completely backward compatible. We can always expect a constant connection regardless of cable and router. If you connect an old cable with a newer router, the network works just like with a new Ethernet cable. The speed of the connection, however, depends on the less capable device.

Also, Ethernet is much more secure compared to Wi-Fi. Data leaks have increased with the rise of wireless technology as it gives cyber attackers more leeway. Wireless networks and especially public ones are attack grounds for hackers. Contrary to this, to use Ethernet, it is always necessary to connect the router to the device using a cable.

The wired connection is also reliable due to its ability to reduce noise. You can thus connect a series of computers at a maximum distance of 10 kilometers. In addition, the network allows you to perform intensive tasks such as mining.

For large industries, Ethernet continues to be the solution because it allows for intensive tasks such as virtual communication. It is also the most suitable network for employees who work from home, but not only. At home, the cable connection can also satisfy fans of online gaming and streaming.


In addition to its advantages, there are also disadvantages of the wired Ethernet network. First, it is not the ideal solution for those who travel frequently. It is quite adapted to the house, but it is still necessary to connect a cable in each part. Not to mention the cables, which must be long enough to connect each room to the router. This can cause crosstalk.

In addition, the mobile devices they are not welcome on the wired network because they do not have a specific port to connect the Ethernet cable. As a result, it is impossible to connect with a smartphone or tablet.

In addition, the wired network causes high equipment costs and Installation Nothing is easier than setting up Ethernet for a single room. However, when it comes to extending it to an entire building or campus, a larger investment is required.

Also, if problems do occur, it is practically difficult to locate their origin, especially when there are different switches. It is difficult to trace the node or cable responsible for the failure.

Ethernet and Wi-Fi, what is the difference?

Ethernet remains a major competitor to Wi-Fi wireless networking. Both have strengths and weaknesses that can influence users’ choice. In this section, we will discover their respective characteristics:

Ethernet, the wired network

As its name suggests, Ethernet is a wired network. Requires a cable to connect the router to devices; that limits your mobility. In addition, its installation is not only expensive, but also time and energy consuming.

However, if you want to bet on the quality of the connection, it is the right solution for its constant speed and the almost nonexistent latency. Also, data encryption is not required as Ethernet provides a secure connection.

Wi-Fi, the wireless network

more convenient and less expensive to install, Wi-Fi network is also popular. In fact, it offers great mobility to its users who can connect anywhere without the need for a cable. Smartphones and other mobile devices can also connect to Wi-Fi seamlessly.

On the other hand, the connection to Wi-Fi is not as stable as that of Ethernet. The data transmission speed varies constantly. In addition to that, it requires data encryption. However, if a Wi-Fi router can accommodate more devices, it is susceptible to interference and piracy.

What about Ethernet at home?

Ethernet is the most suitable network for home use. To do this, you must first have devices that have Ethernet port. Additionally, you will need one or more cables, such as Cat-5 or Cat-6, as needed.

In addition to your PC, you can also connect your game console to your router. If you are more of a fan of Netflix or Disney+, just connect your streaming device to the router. Sometimes you have to use a USB adapter to Ethernet such as TP-Link USB-A if your device requires it.

The central element of an Ethernet network is, of course, the router. The wireless router may have one or more Ethernet ports. If the number of ports matches your needs, all you have to do is connect them. On the other hand, if the router does not have enough ports for your devices, you should use a network switch.

In conclusion

For one thing, Ethernet flourished during these years and is still widely used despite its flaws. On the other hand, IEEE is still looking for innovation to allow you to remain competitive even in this age of wireless technology. So we can expect new official standards in the coming years: 800 GbE and 1 TbE, among others.
