Tap

Tap may refer to any of the following:
1. When referring to a touch screen, a tap is a quick, gentle touch on the screen with a finger. Tapping once opens an app or selects an object. It's very similar to a single click using a mouse.
Tip
Like a mouse, there are also programs that support the ability to double-tap, which means tapping two times on the screen. Some phones also support tap and hold, which is tapping the screen with your finger and holding it in place to get additional options.
2. A tap describes an access point onto a LAN (local area network).
