TL;DR

This blog explores the fundamentals of Ethernet technology, its types, advantages over wireless alternatives

Key takeaways

  • When connecting cables from one computer to another with the aim of having a Local Area Network (LAN), we are sometimes less susceptible to what we are doing.
  • It sometimes skips our minds that Ethernet, which has been with us for a while now, is responsible for that connection.
  • While many people use it often without understanding it, the computer networking world wouldn’t be where it is without Ethernet.

When connecting cables from one computer to another with the aim of having a Local Area Network (LAN), we are sometimes less susceptible to what we are doing. It sometimes skips our minds that Ethernet, which has been with us for a while now, is responsible for that connection. While many people use it often without understanding it, the computer networking world wouldn’t be where it is without Ethernet. Ethernet offers us a whole new world of secure LAN, which wouldn’t be possible to attain over wireless fidelity (Wi-Fi).

Understanding Ethernet

Ethernet is a wired technology in the computer networking family mostly used on LAN. Wired LAN is a computer as well as other electronic devices network covering a small area like an office, a room, or a building. This system of computer connection allows us to form a local area network when we connect a number of computers to it. The aim of the local area network is to control the passing of information and avoid simultaneous transmission by two or more systems.

The Ethernet network protocol controls data transmission over LAN in a protocol referred to as the IEEE 802.3 protocol. The evolution and improvement over time of this protocol have been tremendous. It has now reached a mind-boggling data transfer speed of up to one gigabit per second.

Most desktop computers, as well as laptops, have an integrated Ethernet card that is ready to connect to an Ethernet Local Area Network.

How it Works

A technical knowledge of Ethernet protocol in computer science is required to understand fully how the ethernet works. When a machine wants to send data to another one on a network, it senses the carrier – the main wire connecting the devices. When it is free and no one is sending data, it sends the data packet to the network, and at this point, the other devices check the packet to see if they are the recipient. The recipient then consumes the packet. When there’s a packet on the way, the sending device holds back for a thousandth of a second to try until it can send the packet.

Types of Ethernet

  • Fast Ethernet. This Ethernet connection type has high transmitting speeds of up to 100 Mbps. You need a twisted pair of Cat5 cables to operate this Ethernet connection type.
  • Gigabit Ethernet. If fast Ethernet is not fast enough for you, perhaps you need something faster. This is where Gigabit Ethernet comes in. With speeds of up to 1Gbps or 1000 Mbps, it is slowly phasing out Fast Ethernet. It is suitable for more advanced tasks, and it supports video streaming much better.
  • 10 Gigabit Ethernet. This is next-level innovation. Its use will become more frequent in the future since Gigabit Ethernet is quite stable. With speeds of up to 10-Gbps, you will need a Cat6a or Cat7 twisted pair cable or a fiber-optic cable.

Advantages of Using Ethernet

  • Stability: Ethernet’s internet connections are much more stable than those offered by Wi-Fi. Tethered cables are more stable than wireless frequency dependency.
  • Speed: Ethernet is faster than Wi-Fi since it instantaneously transfers data by use of cables, unlike Wi-Fi which has to diffuse data transfers over radio waves.
  • Security: With Ethernet, you enjoy much more secure connections since the control of who can access LAN is determined by you. If somebody is not connected to the LAN, there’s no way they can access the data or the devices.
