Sunnat-e-muakkadah aur Sunnat-e-ghair muakkadah me farq

Q: Masla ye he ke sunnat-e-muakkadah owr sunnat-e-ghair muakkadah me koi faraq he ya nahi? Kuch saathi kehte he ke sunnat-e-muakkadah yani zuhr ki chaar sunnat me do rakat ke darmiyaan jab qa'da karte he to attahiyyaat sirf parhenge aur sunnat-e-ghair muakkadah yani esha ya asr ki chaar sunnat, us me do rakaat ke darmiyaan me attahiyyaat ke saat durood shareef bhi parhenge. Is ki wazaahat karde. Agar koi aur farq bhi ho to bata dijiey.

Sunnat Salaah before zuhr

Q: I would like to ask concerning about the 4 raka'at sunnah before zuhr. I heard someone say that there should only be one salaam in the entire 4 raka'at. Then someone told me that there should be 2 salaams, now I'm confused. Which one is correct? or it depends on which madhhab I follow? Please elaborate.
