The iPad
 
The iPad has very few exterior buttons. You navigate content with touch gestures — for example, tapping an icon to start an app. Some gestures perform standard functions, such as displaying different menu icons, and some perform functions specific to an app.

Description
The Home button wakes the tablet when it is sleeping and exits apps, returning you to the home screen.
*Remember, the more apps that you have running, the more memory and battery power your tablet uses. To optimize the performance of your tablet, try to close apps when you finish with them.
