Is Ethernet a LAN or WiFi?

Ethernet is a technology used for wired local area networks (LANs), while Wi-Fi is a technology used for wireless local area networks (WLANs).

1、Ethernet (LAN):

Ethernet is a standard for wired LANs, where devices are connected to a network using physical cables. It defines the way data is transmitted over the cables and how devices communicate with each other. Ethernet is commonly used in homes, offices, data centers, and other environments where a reliable and high-speed wired connection is required. Ethernet cables typically use twisted-pair copper wires or fiber optic cables to transmit data.

2、Wi-Fi (WLAN):

Wi-Fi, on the other hand, is a technology that enables wireless communication between devices over short distances. It allows devices like computers, smartphones, tablets, and other Wi-Fi-enabled devices to connect to a wireless access point or router, creating a local wireless network within a certain range. Wi-Fi is widely used in homes, public places, coffee shops, airports, and many other locations where users need the convenience of wireless connectivity.

In summary, Ethernet is a wired LAN technology, while Wi-Fi is a wireless LAN technology. Both Ethernet and Wi-Fi are commonly used to connect devices to a local network and provide internet access and communication between devices within that network. The choice between Ethernet and Wi-Fi depends on factors like the required speed, distance, mobility, and the availability of infrastructure.
