Begin by pressing the hold and home buttons at the same time. The hold button is the one on the top right corner of the iPad. The home button is the round one at the bottom center of the iPad's front
Continue to hold these buttons until one of two things happen: either the screen will flash and go dark, or a red slider will appear at the top of the screen
If the slider appears, you can slide it to the right to turn off the iPad (or tap the cancel button if you change your mind)
When the iPad's screen goes dark, the iPad is off
Restart the iPad by holding down the Hold button until the Apple icon appears. Let go of the buttons and the iPad reset will be complete.

In some cases, reset can also refer to restoring the iPad to its factory settings and deleting all data. In any case it is recommended u back ur important data.
