Wired Internal Network Card for PCI Express x1

Get Connected With PCIe Internal Network Cards

Network cards allow you to connect your desktop or another device to the internet and business networks. Many motherboards have an adapter built-in, but you can also select from cards that can be installed into your PCI Express slot. When selecting a PCIe wired internal network card, there are different styles and models available.

How do you choose an internal network card?

The PCI Express port on your motherboard is one of the most common ports used for an internal network adapter. When selecting a network adapter, you should evaluate how much bandwidth is needed for your system. The downstream data rate from your device manager will determine how quickly the system can transfer data by networking with another website or computer. This will be listed in either Mbps or Gbps. Another item to consider is the type of network port adapter that you want to use. The two main types of adapters used may be either an Ethernet port or fiber optic USB cable. Lastly, you may want to choose a brand of an internal network adapter. There are several branded options like IBM, Intel, Realtek, D-Link, and others. You can also choose from various unbranded and generic options.

What is a multiport network card?

This type of adapter allows for up to four separate network connections to be added to your computer using a single PCI Express port. Some enterprise applications, such as a virtualized environment, need access to multiple networks. With multiple separate connections you can get up to 1000 Mbps in up and down rates.

What are some of the components of a NIC?

  • RJ-45 slot: This jack generates and receives the signals that are sent over the network cable. This component will have an indention in the top that allows the Ethernet cable to be locked into place.
  • PCI interface: Most NICs will connect to the motherboard’s PCIe slot. Some models will be compatible with various models. This part of the card allows data to come from the motherboard.
  • Controller: This CPU is responsible for reading and encapsulating data so that it can be sent out on the Ethernet connection and also removes incoming packet’s encapsulations as well.
  • EPROM: The erasable/programmable read-only memory chip stores the firmware for the card. This chip allows the card to be updated and provided with code fixes when needed.

What are intelligent NICs?

These types of network adapters feature multiple processors that assist in monitoring the incoming traffic. With intelligent and smart NICs, the extra processors allow the card to handle a portion of the network’s workload. Some of these network adapters will also analyze incoming data to filter out malicious data. Lastly, these cards can handle higher amounts of bandwidth at a fast rate.
