What term describes a technology that allows devices to connect to the LAN using an electrical outlet?

• A. Powerline Networking
• B. Internet
• C. Intranet
• D. Extranet

Answer: (A)

Powerline networking uses existing electrical wiring in a building to carry data, letting devices connect to the LAN through power outlets. A pair of adapters plugged into outlets near the router and near devices conveys Ethernet traffic over the home’s electrical wiring, often with the option to connect devices via Ethernet or extend wireless coverage. This approach avoids running new cables and can help reach rooms where Wi‑Fi or Ethernet is difficult. Standards like HomePlug or G.hn govern how the signals are modulated over the wires, but the main idea is using power lines as the network medium. The other terms don’t fit because the Internet is the global collection of networks, an intranet is a private network inside an organization, and an extranet extends that private network to selected external partners.
