Notice that "middle C" is on the first ledger line below the treble clef (stave) and is also on the first ledger line at the top of the bass clef (stave). These are the same note. It's called "middle C" because it is in the middle of the piano.

Explanation:

Middle C is the note exactly between the bass and treble clefs, as noted in the image above. It is known by many other names, but for these tutorials I will be calling it "middle C". Middle C is located in a different spot for each clef, but it remains the exact same pitch.
