What Is The 10Gb Network Card?
The 10gb network card or 10gb nic (Network Interface Card) is the device that makes it possible for your computer to connect to the network, mostly to a LAN. In most computers, the network card is embedded in the motherboard but it can also be replaced or used as an external component. The most common classification of the network cards is on the basis of speed, the 10 gigabit network card means it can support speed up to 10Gbps. However, that does not mean you will get 10Gbps speed, the actual speed depends on the ISP. This means if you get a 40Gb network card but your ISP offers just 1Gbps, then 1Gbps is the maximum that you can expect.
Network cards are widely used, and there are many different types on the market, such as PCIe network cards and server network cards. PCIe network cards are common in most computers and some network servers. In addition, server network cards can also be inserted into the expansion slots of the device.
Most network cards operate at least up to 1Gbps speed. However, to stay on the safer side, having a 10gb network card is ideal, for it leaves the possibility of making use of the higher speed offered by your ISP. So which is the best 10gb NIC and what should you look at while searching for the best network card? To eliminate your confusion on how to pick up the best 10gb network card in 2021, we have highlighted the best ones along with a section on how to choose them.

How To Pick The Best 10GB Network Card
While the above 5 are the best 10Gb network cards that you can get from Amazon, your search is still not over. Picking out the best 10gb network cards is about ensuring that all-important factors are considered. These factors and considerations are what we will discuss next.
The interface that the NIC connects to is an important factor. PCI is the preferred choice in desktop computers, while most laptops use PCMIA. With PCMIA cards, you also need to consider if you will need any additional cables and if the right type of slots is present.
Most networks today use RJ-45, so this should be the preferred choice while buying the best network card. However, if your network uses some other interface like coax, then you need to ensure that the network card you get supports it.
Operating System Compatibility
While most network cards support all major operating systems, this is still an important consideration for a hassle-free installation and peak performance. Ensure that the NIC is compatible with your preferred OS, be it Windows 10, Server, or any Linux-based OS.
Warranty and Technical Support
Choose a network card that has at least 1-3 years of warranty including coverage in case of any defects. Also, does the manufacturer offer technical support, and is it 24/7? Both these things are important to get the most out of your investment and ensure stable and reliable connectivity.
The Function Of The 10GB Network Card
The definition of the 10gb network card is very simple, but what are the specific functions? As the interface of the TCP/IP layer, the network card can transmit signals at the physical layer and data packets at the network layer. No matter where it is located, it acts as an intermediary between the computer or server and the data network. When a user sends a web page request, the 10 gigabit network card obtains data from the user’s device, sends it to the web server, and then receives the required data and displays it to the user.
The Structure Of The 10GB Network Card
The 10gb network card is generally composed of a controller, a boot ROM slot, one or more network card ports, a motherboard interface, an LED indicator, a bracket and some other electronic components. Each component has its own unique function:
Controller: The controller is like a micro CPU to process the received data. As the core part of the network adapter, the controller directly determines the performance of the network adapter.
Boot ROM slot: This slot on the network card can enable the boot ROM function. The boot ROM can connect diskless workstations to the network, which improves security while reducing hardware costs.
Network card port: Normally, this port is directly connected to an Ethernet cable or optical module to generate and receive electrical signals on the network cable or optical fiber jumper.
Bus interface: This interface is located on one side of the circuit board and connects the network card and the computer or server by inserting the expansion slot.
LED indicator light: The indicator light is used to help users identify the working status of the network card, confirm whether the network is connected, and whether the data is transmitting.
Bracket: There are two types of brackets on the market, one is a full-height bracket, and the other is a half-height bracket. This bracket can help users fix the network card in the expansion slot of the computer or server.
Types of The Best Network Cards
According to the host interface, transmission speed, application area, the network card can be divided into the following different types.
Classification Based On Network Connection
Based on the way the network card accesses the network, the network card can be divided into the wired network card and the wireless network card. As the name implies, a wired network card usually needs a jumper (such as an Ethernet jumper and an optical fiber jumper) to connect a node to the network; a wireless network card usually has a small antenna that uses radio waves to communicate with the access point to connect to the wireless network.
Classification Based On Bus Interface Type
ISA bus network card: ISA bus was released in 1981 and is a bus structure compatible with IBM standards. Due to the slower speed of the 9Mbps network card, the ISA bus interface is gradually eliminated, which is rarely seen in the market now.
PCI bus network card: PCI was released in the 1990s and replaced the previous ISA standard. Its fixed width is 32 bits (data transfer rate is 133MB/s) and 64 bits (data transfer rate is 266MB/s). Most computers today do not have expansion cards, but instead use embedded network cards. Therefore, the PCI bus network card has been replaced by other bus interfaces, such as PCI-X or USB interfaces.
PCI-X network card: PCI-X is an enhanced PCI bus technology. It supports 64-bit operation, up to 1064MB/s. In most cases, PCI-X slots are backward compatible with PCI network cards.
PCIe network card: PCIe is the latest standard, very popular on computer and server motherboards. There are now five versions of PCIe network cards, each supporting different speeds.
USB network card: USB bus is an external bus standard. It has three versions with different transmission rates and can work with various devices.
Classification Based On Port Type
According to different connection wires, there are four types of network card ports on the market. RJ-45 port is used to connect twisted pair cables (such as Cat5 and Cat6), AUI port is used for thick coaxial cable, BNC port is used for thin coaxial cable, and optical port is used for modules (Such as 10G optical module).
Classification Based On Transmission Speed
Based on different speeds, there are 10Mbps, 100Mbps, 1000Mbps, 10G, 25G and even higher speed network cards. 10Mbps, 100Mbps network cards are suitable for small local area networks, homes or offices. The 1000Mbps network card can provide higher bandwidth for Fast Ethernet. 10Gb network cards and higher speed network cards are welcomed by large enterprises and data centers.
Classification Based On Application Fields
Computer network card: Most new computer motherboards now have a built-in network card, so there is no need for a separate LAN card. It usually has speeds of 100Mbps and 10Gbps, and allows one computer to communicate with other PCs or networks.
Server network card: The usage of the server network card is to manage and process network traffic. Compared with ordinary computer network cards, server network cards require higher data transmission speeds. In addition, the CPU occupancy rate of the server network card is very low, because it has a special network controller that can reduce the burden on the CPU. In order to meet the different needs of users for the speed of server network cards, many companies on the market have introduced 10GB PCIe network cards and 40G network cards.
FAQs When Picking The Best 10GB Network Cards
- Does a network card support lower speeds?
Yes, most NICs or network cards are backward compatible. If you get a 10Gb network card, it will support speeds from 10Gb to 100 Mb in most cases.
- What is PCIe and how is it relevant to network cards?
PCIe or PCI express is an updated version of the interface that is used for motherboard-level connections including network cards. PCIe cards are available in 5 sizes, from 1 to 32, with each referring to the number of lanes in the slot. For network cards, PCIe x8 and x16 are the common variants. You can place a PCIe x8 card in an x16 slot, but not vice versa.
