2.2.16 Network Interface Cards (NICs) - Notes
Most motherboards already have Ethernet built into the chipset. A dedicated NIC is added when you need to upgrade or expand network capabilities.
Reasons to Add a Dedicated NIC
- Upgrade to a different network type, such as copper to fiber optic
- Add multiple ports that can be bonded into one higher-bandwidth link
- Add Wi-Fi or 802.11 wireless support
- Connect to cellular data networks
NIC Types
| Type | Connection | Use |
|---|---|---|
| Ethernet NIC | RJ45 port | Wired network via copper cable |
| Fiber NIC | Fiber optic port | High-speed or long-distance wired network |
| Wi-Fi adapter | Wireless | Connect to 802.11 wireless networks |
| Cellular adapter | Cellular | Mobile data network connectivity |
Key Things to Remember
- Onboard Ethernet is already built into most motherboards through the chipset.
- A dedicated NIC typically installs into a PCIe or PCI slot.
- Multiple NIC ports can be bonded together into a single faster connection.
- Wi-Fi cards support different 802.11 standards such as a, b, g, n, ac, and ax.
