Answer: Option D
Solution(By Examveda Team)
Wireless Communication:Wireless communication is the transfer of information over a distance without the use of wires or cables.
It relies on various electromagnetic waves to transmit data.
LAN (Local Area Network):
A LAN is a network that connects devices within a limited geographical area, such as a home, office, or school.
LANs can be wired (using Ethernet cables) or wireless (using Wi-Fi).
WAN (Wide Area Network):
A WAN is a network that connects devices over a large geographical area, such as a city, country, or even globally.
WANs typically use a combination of wired and wireless technologies.
Examples include the internet.
PAN (Personal Area Network):
A PAN is a network that connects devices within a very small area, typically around a person.
PANs are often wireless, using technologies like Bluetooth or near-field communication (NFC).
Correct Answer: Option D - All of the mentioned
While LANs and WANs can utilize wired connections, they also commonly incorporate wireless technologies (Wi-Fi for LANs and various wireless technologies for WANs). PANs are almost exclusively wireless. Therefore, all three (LAN, WAN, and PAN) can be considered types of wireless communication in certain configurations.
