The two types of external NICs are Wireless and USB-based.
Exploring External NIC Types
A Network Interface Card (NIC), sometimes called a network adapter, is hardware that allows a computer or other network device to connect to a network. While many devices have built-in NICs, external NICs are used to add networking capabilities to a device, often when the built-in option is missing, damaged, or needs an upgrade (like adding Wi-Fi to a desktop or an Ethernet port to a slim laptop).
Based on external connectivity and function, there are specific types available, including Wireless and USB-based external NICs.
- Wireless NICs: These adapters have an antenna to provide wireless network reception. They allow devices to connect to a network without using cables, relying instead on radio waves (like Wi-Fi).
- USB-Based NICs: These adapters provide network connections through a device that plugs directly into a USB port on the computer or device. They are often used to add wired Ethernet connectivity via a USB port.
Here's a quick comparison based on the reference:
| Type | Connection Method | Physical Feature | Primary Function |
|---|---|---|---|
| Wireless | Wireless (Radio Waves) | Has an antenna | Provides wireless reception |
| USB-Based | Wired (via USB Port) | Plugs into USB | Provides network connections |
Practical Uses
External NICs offer flexible solutions for various networking needs:
- Adding Wi-Fi capability to older desktop computers that lack an integrated wireless adapter.
- Providing a wired Ethernet port to modern laptops or tablets that are too thin to include one.
- Replacing a broken internal network adapter without needing to open the device.
- Upgrading to a faster Wi-Fi standard (e.g., Wi-Fi 6) or Ethernet speed (e.g., 2.5 Gbps) that isn't supported by the built-in NIC.
By utilizing either a Wireless or USB-based external NIC, users can easily enhance or restore a device's ability to connect to a network.
