What aspect of networking does Wi-Fi primarily pertain to?

Wi-Fi primarily pertains to wireless communication because it enables devices to connect to the internet or network without physical cables. This technology uses radio waves to transmit data between a wireless access point and devices like laptops, smartphones, and other gadgets equipped with Wi-Fi capabilities. Wireless communication is characterized by its flexibility and mobility, allowing users to access network resources from various locations within the range of the Wi-Fi signal.

In contrast, wired communication refers to traditional network setups involving physical cables like Ethernet, which do not allow for the same level of mobility. Fiber optics transmit data as light signals along thin strands of glass, representing another type of wired communication. Satellite communication relies on satellites to relay signals for networking over great distances but does not directly relate to the standard implementation of local networks typically associated with Wi-Fi. Therefore, the identification of Wi-Fi with wireless communication is due to its method of connecting devices through radio frequency rather than physical connections.
