Wireless Networks in Simple Terms WLAN and Wi-Fi defined

What is Wi-Fi?The term Wi-Fi is often used as a synonym for wireless local area network (WLAN). Specifically the term "Wi-Fi" is a trademark of a trade association known as the Wi-Fi Alliance. From a technical perspective WLAN technology is defined by the Institute of Electrical and Electronics Engineers (IEEE).

In computer networking everything starts with the physical layer, which for many years was a copper wire. The physical layer was expanded to include anything that represent the wire, such as fiber optic cable, infrared or radio spectrum technology.

Wireless network refers to any type of computer network that is not connected by cables of any kind. While cell phone technology is often discussed as a form of wireless networking, it is not the same as the wireless local area network (WLAN) technology discussed here.
