A wired network connection requires the use of:

• A. NIC, copper cabling, switch, router.
• B. Wireless NIC, WAP, router
• C. NIC, WAP, switch.
• D. NIC, WAP, switch, router.

Answer: (A)

Understanding wired Ethernet networks starts with the idea that every device on the network needs a network interface to speak on the network, a physical medium to carry the signals, and a device to coordinate traffic. A Network Interface Card (NIC) is the essential adapter inside each device. Copper cabling (like Ethernet cables) is the common physical medium that carries those signals between devices. A switch ties multiple devices together on the same network segment, allowing them to communicate and share resources efficiently. To reach other networks or the Internet, a router is needed to route traffic between networks and often to perform network address translation (NAT), enabling access to external networks. Wireless components aren’t part of a wired setup; a wireless NIC and a wireless access point belong to wireless networks and aren’t required for a wired-only connection. While a network can function without a router if no external connectivity is needed, having a router is necessary to connect to other networks or the Internet. So, NIC, copper cabling, switch, and router together cover the essential hardware for a typical wired network with external connectivity.
