Answer 1

The correct answer is Wireless LAN.

Key Points

Wireless LAN (WLAN) uses high-frequency radio waves to communicate between devices, eliminating the need for physical cables.
These networks typically operate within the 2.4 GHz or 5 GHz frequency bands, which are designated for unlicensed use in most countries.
WLANs are common in homes, offices, and public spaces, providing mobility and ease of network expansion.
They often use standards such as IEEE 802.11 (commonly known as Wi-Fi) for communication.

Additional Information

Bluetooth LAN: Bluetooth is a short-range wireless technology standard used for exchanging data between fixed and mobile devices over short distances, but it is not typically used for creating a full-fledged LAN.
Wired LAN: Wired LANs use physical cables (like Ethernet cables) to connect devices, providing reliable and fast connections but lacking the mobility of wireless connections.
