Settings > Connections > Wi-Fi > On/Off

Wi-Fi is a term used for a wireless network technology that provides wireless high-speed internet and network connections without using the data allocated to your service plan. When Wi-Fi is turned on, your device automatically scans for available networks and displays them. You may be required to enter a password to connect.

When you select a public/unprotected network, you are automatically connected to that network. Connecting to a public Wi-Fi network can leave your personal data vulnerable, so it is important that you connect to known, secure networks and set up passwords as necessary.

Wi-Fi Direct 

Settings > Connections > Wi-Fi > More (3 dots) > Wi-Fi Direct

This feature uses Wi-Fi capability to share data between Android devices even if they are from different manufacturers. To connect, both devices must have Wi-Fi Direct turned ON, but will not need to be connected to a Wi-Fi network.
