Wi-Fi

From Computing and Software Wiki

Wi-Fi is a consortium that verifies 802.11b wireless network products interoperate, and a marketing term vendors use to sell their products.^[1]

Wi-Fi is a subsection of the IEEE 802, a subcategory in the link layer of the TCP/IP Internet Protocol Suite. The Wi-Fi alliance is a trade group that owns the 'Wi-Fi' trademark, a symbol that certifies interoperability between wireless devices. Not every Internet product is Wi-Fi certified however, and there exists many devices that are able to interoperate wirelessly without the Wi-Fi logo. Some products have chosen to omit having Wi-Fi certification to avoid paying certification costs.

The use of Wi-Fi has boomed in recent years and is supported by a multitude of different devices. Laptops. game consoles, smartphones, printers and other peripherals usually have Wi-Fi certification.
