Integrated card - two Intel 1000M Lan RTL8111E (optional WiFi module) allows connection to the network. The computer is equipped with: two LAN ports, six COM ports (RS232), one VGA output, six USB 2.0 ports, one way audio, one microphone input and connectors built into the motherboard: four USB 2.0 ports, two PowerOUT outputs, one audio output, one CPUFAN, one GPIO connector.

General-purpose input/output (GPIO)
This is a generic pin on an integrated circuit whose behavior, including whether it is an input or output pin, can be controlled by the user at run time. GPIO pins have no special purpose defined, and go unused by default. The idea is that sometimes the system integrator building a full system that uses the chip might find it useful to have a handful of additional digital control lines, and having these available from the chip can save the hassle of having to arrange additional circuitry to provide them.. 

Two independent network cards Intel RTL8111E
The computer can use two network cards for different purposes - it can be very practical - for example - when one card is responsible for the Internet connection, and the other keeps the connection of devices in the factory, warehouse, shop, supermarket and even in bank that should not have its own connection to the Internet.
