Greetings and welcome to the forum!
When you get some time, I suggest you download a copy of the
iPad User Guide. It is available for free in several different formats.
a) As a free PDF download from the Apple website --
Apple - Support - Manuals
This can (and should!) be saved on your computer and your iPad.
b) As a free iBook once you download the free iBook app from the iTunes App Store.
c) Online using the link provided in the Safari favorites on your iPad.
The answers to many questions, especially if this is your first Apple mobile "iDevice", can be answered by spending some quality time with this handy document.
