The internet is the largest _________ that connects billions of computers, smartphones, and devices from different continents.

Correct option is A

The internet is considered the largest Wide Area Network (WAN). It connects millions of smaller networks, including Local Area Networks (LANs) and Metropolitan Area Networks (MANs), allowing global connectivity.
Important Key Points:
1. WAN (Wide Area Network) - A type of network that spans a large geographic area, often interconnecting smaller networks like LANs and MANs.
Knowledge Booster:
· MAN (Metropolitan Area Network): This network covers a city or a large campus, but it cannot cover global areas like a WAN.
· LAN (Local Area Network): This is used to connect devices within a small geographic area, such as a building, not suitable for worldwide connectivity.
· PAN (Personal Area Network): A small-scale network used for personal devices, such as Bluetooth or USB connections, not for global networking.
