The Major & Minor Scales/Modes
While the Pentatonic Scale is a 5-note scale (hence: pent means five), the Major Scale is a 7-note scale. The Pentatonic Scale actually comes from the Major Scale.
Here are the seven positions of the Major Scale. Each position is a mode, or you can just refer to them as position I, position II, etc.
While all of the positions as a whole is the Major Scale,
position I--Ionian--is usually referred to as the Major Scale, &
position VI--Aeolian--is usually referred to as the Minor Scale.
Here they are.
