A desktop PC is being installed in a cubicle and will connect to the company LAN using a standard RJ-45 Ethernet cable. Which type of network interface card (NIC) should be installed to enable this connection?
Wireless (802.11) NIC
Bluetooth NIC
Cellular (4G/5G) NIC
Wired Ethernet NIC
Because the PC will use an RJ-45 Ethernet cable, it needs a wired Ethernet NIC-sometimes called a wired LAN adapter. A wireless NIC uses radio waves (Wi-Fi, Bluetooth, cellular) and does not provide the RJ-45 port required for a cabled Ethernet connection. Bluetooth and cellular adapters also operate wirelessly and are unsuitable for a copper-cable Ethernet link.
