Definition of Ethernet Ports
LAN Ports vs Ethernet Ports
You might often hear the technical word Ethernet in offices, schools, or companies. As a family member of wired computer networking technologies, it is used to achieve internet connections within a LAN (Local Area Network). In another way, Ethernet is equal to a protocol allowing smooth communication between various devices on a LAN.
However, when it comes to some computer hardware, the objects that first come into your mind may be keyboards, computer screens, core processing units, etc. This blog will show you a computer hardware called the Ethernet port. Also called LAN port, RJ45 port, Ethernet jack, or Ethernet socket, it is a pivotal physical interface found on lots of electronic devices (e.g., computers, routers, modems, and gaming consoles), mainly facilitating the connection to wired networks.
For most home routers, the LAN ports bear the same meaning as Ethernet ports. You can use either of them at your free will. How to identify them is a question, and you can look at their physical characteristics.
Physical Appearance
Looking at its physical appearance, you can recognize something about the size of a thumb, which usually takes a rectangular shape with a slightly sloping edge. This setup is just hidden on your laptop’s side or back edge. This piece of hardware consists of eight small metallic pins distributed in a single row, which connect to the wires within Ethernet cables. Ethernet ports are slightly wider than a cellphone jack, making them much easier to plug in Ethernet cables. Just observe what it looks like in Figure 1.
Ethernet Port Types
Relying on different speeds and types of connections, Ethernet ports come in various types. The following are the four significant specifications in the electronics market.
The Fast Ethernet Port: It can deal with speeds of up to 100 Mbps and has been considered to be an industrial standard for years; however, many companies have thought of it as something behind the times.
The Gigabit Ethernet Port: It is the popular type used for electronic devices, allowing the handling of speeds more than 1 Gbps.
The 10 Gigabit Ethernet Port: It is possible to process speeds of over 10 Gbps, and high-performance networking devices commonly use this type.
Multi-Gigabit Ethernet Port: It permits speeds surpassing 10 Gbps, such as 25 Gbps, 40 Gbps, or 100 Gbps. This port is often intended for high-demand setups or data centers.
How Do Ethernet Ports Work
Connecting to Network Interface Controller (NIC)
As an essential component linking devices to LAN and the internet, the Ethernet port is embedded into the architecture of various devices via the Network Interface Controller (NIC). Known as an Ethernet card, the NIC links your computers or other devices to wired networks. Although many types of NICs exist, they commonly fall into two categories.
The first is the wired NIC, which can ensure the use of relatively stable and high-speed networking connections, while the second, the wireless NIC, is to make connections to WiFi networks.
How to choose a suitable NIC is a key problem in keeping wired network connections reliable. If you are eager to enhance your network connection speed and ensure network stability, our Cat6/Cat7/Cat8 Ethernet Network Patch Cables offer you top-notch options used to handle the process of allowing fast data transfer via your Ethernet ports.
Role of Ethernet Ports in Connecting to the Internet
According to its definition, the Ethernet port is a docking station where electronic devices use cables for their connections. In modern society, with the advancement of technologies, wireless network connection is increasingly popular; however, connections through Ethernet ports can be much more reliable because they are less vulnerable to interference or unauthorized access. Therefore, such ports are preferable for application scenarios where users must ensure network reliability.
Besides, compared to most wireless networks, Ethernet connections, including Multi-Gigabit and Gigabit, can allow data to transfer at a higher speed. The Ethernet port primarily creates a direct internet connection from your computers to networking devices through Ethernet cables. Another word for this process is hard wiring, which can ensure you obtain a fast and stable internet service.
You can connect various devices like personal computers using an Ethernet cable to link up to an Ethernet port. If you need reliable connectivity and avoid latency issues arising from wireless networks, you can use Ethernet ports.
Connecting Devices Using Ethernet Ports
When establishing a network, you need to know how to select the proper type of Ethernet cables to ensure optimal network performance. Various types range from Cat5e (used for basic networking) to Cat6 or Cat6A (preferred for scenarios demanding higher data transfer speeds and less interference). Without the recognition of ANSI/TIA in North America, Cat7 Ethernet has the equivalent function as Cat6A. In addition, Cat8, which has particular uses, can play the role of Cat6A past 98 feet length.
Ethernet cable types have various features, such as different shielding levels and frequency capabilities, which may undermine their suitability for various networking environments. The table below will provide an understandable table to help you determine Ethernet cables’ bandwidth and distance limitations. This is a reminder that the table only provides a prediction of the use of solid copper Ethernet conductors.
| Category | Network Speed length ≤ 98 feet | Network Speed length ≤ 165 feet | Network Speed length ≤ 328 feet |
| Cat5e | 2.5 Gbps | 2.5 Gbps | 2.5 Gbps |
| Cat6 | 10 Gbps | 2.5 Gbps (unbundled) or 120 feet when in bundle | 5 Gbps |
| Cat6A | 10 Gbps | 10 Gbps | 10 Gbps |
| Cat8 | 40 Gbps | 10 Gbps | 10 Gbps |
