DefinitionWi-Fi Direct is a standard that connects Wi-Fi devices directly to each other without a dedicated access point device.
ExplanationOne of the connected devices temporarily doubles as the access point, so devices can talk to each other even where there is no router. For example, a smartphone can send data straight to a printer to print it.
AnalogyIt is like handing a letter directly to the person in front of you instead of sending it through the post office.
