Answer 1

Answer:

Wi-Fi allows local area networks (LANs) to operate without cables and wiring, making it a popular choice for home and business networks. Wi-Fi can also be used to provide wireless broadband Internet access for many modern devices, such as laptops, smartphones, tablet computers, and electronic gaming consoles.

Although Wi-Fi is typically used to access the internet on portable devices like smartphones, tablets, or laptops, in actuality, Wi-Fi itself is used to connect to a router or other access point, which in turn provides internet access. Wi-Fi is a wireless connection to that device, not the internet itself

Wifi in handsets provides an alternative way of accessing the internet from your device other than the data connection provided by your cell phone carrier. ... The other benefit is that in general the connection speeds via wifi are faster than via your cell phone data connection.
