WiFi is the nickname for Wireless Fidelity - high speed internet and network connection without the use of wires, cables and other stuff you can trip over.
Wireless networking-which is often just known as Wi-Fi-is a way of getting broadband internet without wires. Wi-Fi allows you to connect several computers at once, anywhere in the house-or if you have a laptop, to even use your computer in the garden. You donât need to install extra phone lines or cables.
