If the top row of your keys is qwertyuiop then you have a Qwerty keyboard layout. This is the traditional and most common layout, so if you are uncertain you most likely have a Qwerty.

If your keys are not:

qwertyuiop
asdfghjkl;
zxcvbnm

Then reply to me and I can try and figure out what kind of keyboard you have. Cheers!
