Wondering what Gigabit Ethernet is all about and why it has been prominent in networking? Wonder no more, as this article explains all the important factors of this network technology.
Overview
In today’s world, data transfer speed is a crucial factor that can make or hinder the success of an organization or individual. With the increase in the number of applications and devices that need high-speed data transfer, network technologies have evolved to keep up with the demand.
One such technology is Gigabit Ethernet, which is a version of the Ethernet communication network standard. This technology is the speediest version of Ethernet currently available to the majority of people in the world.
Speaking of speed, the network technology is capable of reaching a maximum data transfer rate of 1 Gb (Gigabit) per second. Little wonder it is called “Gigabit” Ethernet!
Due to its insanely fast speed, this technology enables users and organizations to transfer large amounts of data efficiently. Besides that, the technology was first introduced in the late 1990s.
Furthermore, it came as the improved successor to the previous Ethernet version known as “Fast Ethernet.” Compared to the Gigabit Ethernet, Fast Ethernet can only reach a maximum data transfer speed of 100 MB per second.
That’s about ten times less than the maximum data transfer speed of Gigabit Ethernet!
Nonetheless, similar to Fast Ethernet, Gigabit Ethernet operates using copper wire or optical fiber. Additionally, it uses full-duplex communication, meaning data can be transmitted to and fro simultaneously without issues.
That being said, this network technology is widely used in businesses, homes, and data centers where high-speed internet connectivity is needed. Moreover, it is ideal for tasks that require high bandwidth, like online gaming and video streaming.
Features of Gigabit Ethernet
In the previous section, we discussed what this technology is all about. In this section, we will talk about five major features of this fantastic network technology.
Increased Bandwith
Unlike the previous versions of the Ethernet technology, Gigabit Ethernet offers a significant increase in bandwidth. With a maximum data transfer speed of up to 1 Gbps, this technology enables efficient data communication.
Thereby allowing for faster uploads and downloads. Also, the technology better support high-bandwidth tasks such as video streaming and online gaming.
As a matter of fact, its increased bandwidth reduces network congestion, leading to enhanced overall network performance.
Backward Compatibility
Another significant feature of this Ethernet technology is its backward compatibility. Due to this, you can use this network technology with devices that support older versions of Ethernet.
However, the data transfer speed will be limited to the speed that the device’s Ethernet technology supports. Basically, using Gigabit Ethernet on devices that support older versions of Ethernet doesn’t in any way increase the transfer rate.
Nonetheless, the backward compatibility of network technology allows for easy migration. Thus, you won’t need extensive network infrastructure upgrades to migrate from an older Ethernet technology to Gigabit Ethernet.
It uses Full-Duplex Communication
Gigabit Ethernet operates using full-duplex communication, which allows it to send and receive data simultaneously. This feature enables faster data transfer speed and improved network performance.
Besides that, full-duplex communication limits the chance of network collisions, which can cause delays and loss of data.
Has a Quality of Service (QoS) Mechanism
Quality of service (QoS) is a mechanism that works on a network to control traffic and ensure the performance of critical tasks. Thanks to this feature, network administrators can prioritize the network traffic of a Gigabit Ethernet network based on the importance of the data being transmitted.
Therefore, critical network traffic, such as VoIP and video conferencing, receives priority over less critical traffic, like file downloads. In doing so, ensuring network resources are used efficiently.
It has a Lower Latency
Latency is the period it takes for data to transit from one point in a network to another. Thus, with lower latency, this network technology ensures fast data transfer rates and reduced network congestion.
Moreover, low latency is crucial for tasks such as video conferencing and online gaming, where delays can cause performance problems.
Pros Of Gigabit Ethernet
It is more secure than most Network Technologies
Gigabit Ethernet supports several security protocols like AES encryption, MAC address filtering, and 802.1x authentication.
This ensures that data is secure and protected from unauthorized access.
It Consumes Less Power
Power consumption is one of the major advantages of this network technology over other network technologies.
This can make the technology a cost-effective solution for organizations where power consumption is a high cost.
It offers High Data Transfer Speed
The main advantage of using Gigabit Ethernet is its high-speed data transfer rate of up to 1 Gbps.
This makes the technology ideal for data-intensive tasks like video conferencing, large file transfers, and online gaming. Thus, with Gigabit Ethernet, you can transfer large data and files swiftly, thereby increasing productivity and efficiency.
The Chances of Network Congestion are low
With Gigabit Ethernet, the changes of experiencing network congestions, which can cause data loss, are limited.
This is because the technology supports full-complex communication and has low latency.
It is Compatible with Previous Versions of Ethernet Technologies
Gigabit Ethernet is backward compatible, which means it supports devices that use older versions of the Ethernet network technology.
Thus, an organization or user can upgrade their network without replacing their entire infrastructure. However, using Gigabit Ethernet on a device that supports an older Ethernet network won’t enhance the data transfer speed.
Cons Of Gigabit Ethernet
It is Expensive
One of the major disadvantages of using Gigabit Ethernet is its cost of configuration and implementation.
For instance, the technology requires high-quality cables to ensure reliable connectivity. This can increase implementation costs, particularly if you need to replace existing cables.
Besides, to fully utilize the high-speed capabilities of Gigabit Ethernet, you may need to buy additional hardware like routers that support the increased bandwidth. As a matter of fact, maintaining this technology or fixing it can cost you a lot of money.
It is Complex to Install
Setting up this network technology is a very complex process without a skilled network administrator.
Thus, if you decide to install the technology without an expert, you can end up messing up everything. As a result, you should hire an expert when planning to upgrade your network to Gigabit Ethernet.
Single Point of Failure
What this means is that if a part of a technology fails, the entire system will the compromised.
For example, if a Gigabit Ethernet switch or router fails, it can lead to a total network outage. If you don’t have a backup network, this can be very problematic as it can cause delays.
Frequently Asked Questions
Three years after the development of Fast Ethernet, Gigabit Ethernet was developed and introduced in 1998. This Ethernet technology was defined in the Institute of Electrical and Electronics Engineers (IEEE) 802.3 standard.
Furthermore, it is currently used as the backbone of many enterprise networks, thanks to its fast transfer rate.
The main advantage of Gigabit Ethernet over Fast Ethernet is the significantly higher data transfer rate of 1 Gbps. This allows for faster file transfers, downloads, and streaming.
Additionally, this network technology supports more network traffic and devices without causing congestion. Besides, it has lower latency compared to Fast Ethernet.
Gigabit Ethernet makes use of regular Ethernet cables. Specifically, the Category 5e (Cat5e) or Category 6 (Cat6) cables.
These cables feature four pairs of twisted copper wires. Also, they are capable of supporting data transfer rates of up to 1 Gbps, making them ideal for Gigabit Ethernet.
The maximum distance that a Gigabit Ethernet cable can run is 100 meters (328 feet). Beyond that distance, the network signal may become too weak to transmit data.
Yes, Gigabit Ethernet is backward compatible. Thus, it can be used for devices that support older versions of the Ethernet technology.
