The onboard NIC is what is usually called an integrated NIC.

Integrated NIC (Integrated LAN), the practice of integrating the NIC into the motherboard, an integral part of the motherboard, 10M/100M, DUAL NIC, Gigabit NIC and wireless NIC and other types.

Currently, the motherboard integrated NICs have 10M/100M, DUAL NICs, Gigabit NICs and wireless NICs types. For large data volume networks, servers should use Gigabit Ethernet NICs, which are mostly used for the connection between servers and switches to improve the overall system response rate. The 10M/100M network card is the most commonly used and cheapest network chip, it is sufficient for the usual applications such as file **** enjoyment, and the cost of the integrated network chip is now almost the lowest when the cost is quite good. And DUAL Dual NIC technology is certainly the most practical technology for users of applications such as broadband at a modest price.
