Integrated card - Intel RTL8105E 100M (optional WiFi module) allow connection to the network. The computer is equipped with: two LAN ports, five COM ports (RS232), one COM port (RS422/485), eight USB 2.0 ports, one DVI input, one VGA input, 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 JVGA connector, one LVDS connector.

PCI or Peripheral Component Interconnect bus is developed by INTEL in 1992. It has been designed for use adapters that require high-speed transmission. She had to replace the old standard ISA, which she did, because today most motherboards have a few PCI slots. Initially, the PCI card has been designed to supply 5 V, later also introduced 3.3V cards. The PCI 2.3 is valid only 3.3V voltage.

There are slots 32-bit (most commonly used) and 64-bit. 64-bit slots have an additional 32 contacts on each side (because they are longer than the 32-bit). Bit 32 has 62 pins on each side, it has two or four slots (depending on the operated voltage), so the terminal on a 60 or 58 on each side. The possibility of installing the card 32-bit 64-bit slot and vice versa. In the latter case, 64-bit card operates as a 32-bit version.

It is worth noting that all the PCI slots on the motherboard are connected to a data bus, so one of the cards is slower - it will slow down all the other cards.

LVDS Interface
This is a fast digital interface that is used for many applications requiring: a high resistance to interference electromagnetic, low energy consumption at high data rates. LVDS is used in various applications and industries, including commercial and military applications.

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.
