A common misconception is that Wi-Fi stands for wireless fidelity but, in reality, it does not stand for anything. At the time Wi-Fi was invented, it operated under the standards of IEEE 802.11, which was not a catchy or succinct name. While high fidelity was a common sound system term at the time, and Wi-Fi does rhyme with Hi-Fi, there is no relationship between the two.
Wi-Fi is also known as wireless technology that is mostly used to connect computers with access points. However, it has many other similar uses for cameras, tablets, audio players and game consoles as well.
