Wireless Connections
Wireless connections, such as WiFi or Bluetooth, use no cables but require a wireless network interface card (WNIC).
Wireless connections generally have a slower speed and can be affected by the computer's distance from the wireless router as well as obstacles like walls or bad weather.
Wired connections use physical cables, such as copper or fibre optic wires, and require a network interface card (NIC) to connect to a network.
These wired connections use a wired connection protocol - most commonly Ethernet.
