Which technology is commonly used for wired networks?

Ethernet is commonly used for wired networks due to its reliability, performance, and established standards. It functions by using physical cables to connect devices within a local area network (LAN), allowing for high-speed data transmission often exceeding gigabit speeds. This wired technology provides a stable connection, reducing latency and interference that can be more prevalent in wireless connections.

In contrast, Wi-Fi is primarily a wireless technology, enabling devices to connect to the network without physical cables. Bluetooth is another wireless technology, usually employed for short-range data transfer between devices, and is not suited for creating extensive networks. Similarly, cellular technology is utilized for mobile communication, connecting devices to the internet over wide areas but does not typically serve as the backbone for wired local networks.
