Wired and Wireless Networking
How devices connect physically
Wired connections
Wired networking uses physical cables, such as Ethernet cables, to connect devices. Wired links are often fast, stable, and less affected by interference.
Wireless connections
Wireless networking uses radio signals instead of cables. Wi-Fi is the most common wireless technology for local networks, while Bluetooth is common for short-range device connections.
