Wifi simplifies the way to connect to the Internet
What is Wi-Fi?
Wi-Fi is a form of local area networking and wireless Internet access used by people around the world to connect their devices to the Internet without cables.
What does Wi-Fi stand for?
Many people think Wi-Fi is an acronym for Wireless Fidelity. However, the term Wi-Fi is the result of an effort to find a catchy, easy-to-remember name for a new wireless technology invention. Until now, it has been called IEEE 802.11b Direct Sequence.
According to Wikipedia and some other sources, the term Wi-Fi is not an acronym. It was the name proposed by brand consulting firm Interbrand after signing a contract with Wi-Fi Alliance. Wifi has never been a shortened word for Wireless Fidelity.

Meaning of Wi-Fi
Wi-Fi is a wireless networking technology that allows you to connect to the Internet without a network cable. It is also known as 802.11, which is the IEEE standard of wireless local area network (WLAN).
A Wi-Fi network operating in the unlicensed 2.4 GHz and 5 GHz frequency bands. That means it doesn't cause interference with other nearby wireless networks operating on the same frequency or bandwidth.
How does Wi-Fi work?
Modern Wi-Fi works just like a wired Ethernet local area network (LAN) connection. The only difference is that they use unlicensed universal spectrum to transmit data over short distances at high speeds, just like cellular bandwidth operates on mobile devices.
The Wi-Fi standard was developed by the Society of Electrical and Electronics Engineers (IEEE) to provide wireless access in internal areas, often in homes or office buildings.
For Wi-Fi to work, you must have an access point (base station) with a wired connection to connect Wi-Fi devices. Wi-Fi devices communicate with access points using radio frequency signals, just like cordless phones.
How is Wi-Fi used?
Wi-Fi provides an effective alternative to wired networks to share data between devices in the same building or area, such as laptops and smartphones connected to an Internet router to share files.
Wifi also replaces cables running directly from your computer to the router or the Internet, allowing you to access the Internet via Wi-Fi using hotspots.
