Detailed explanation-1: -Wired LANs use physical cables, like Ethernet, and switches; WLANs use devices, like wireless routers and access points, to interconnect network devices through radio frequency waves.
Detailed explanation-2: -To establish an Ethernet connection, you need a network interface card (NIC), a network cable (usually a CAT5 cable), and a network to connect to. Different networks are configured to use different network speeds; make sure your NIC is compatible with the network to which you want to connect.
Detailed explanation-3: -The Ethernet physical layer has evolved over its existence starting in 1980 and encompasses multiple physical media interfaces and several orders of magnitude of speed from 1 Mbit/s to 400 Gbit/s.
Detailed explanation-4: -Network interface card (NIC): Provides the physical connection to the network at the PC or other host device. The media connecting the PC to the networking device plugs directly into the NIC (also known as a LAN adapter).
