Why do most industrial computers have dual LAN ports?

In the early days, most industrial computers had only one network port, which is what we often call a single network port. With the changes in market demand, many industrial computers need more functions, and the single network port has been weak in many applications, which cannot meet the needs of users.

Nowadays, the development of the industrial computer market is also closely following the market demand, and more and more motherboards have their own dual LAN ports. So what are the advantages of the dual LAN ports industrial PC box? Why do most of the industrial computers have dual LAN ports?

To understand the advantages of dual LAN ports industrial computers, the first step we need to know is that dual network ports are mainly applicable to extranets and intranets.

What is an intranet: An intranet is an enterprise network established with Internet technology. In addition to providing functions such as FTP and E-mail, the intranet also provides Web services.

What is an extranet: An extranet is a cooperative network that uses Internet/Intranet technology to connect businesses with their customers and other businesses to accomplish their common goals.

General users use dual LAN ports, and the gateway can set up the internal network and the external network, thus realizing the function of one machine with two networks. Not only the industrial computer, but the server also needs two network ports. Using it as a gateway, one network card is connected to the external network, and the other network card is connected to the internal network. Then the two network cards can be connected to form a gateway. The gateway address on the switch is set to the IP address of the bridge, and the Internet can be shared.

Not only that, dual network ports are also widely used in other application fields, such as firewalls, routers, monitoring system industrial computers and so on. It is believed that in the near future, the application of dual network ports will become more and more common.
