Confusing Boundaries between Police Inquest and Magistrate Inquiry

Yaar samajh nahi aaya, main to AILET ka preparation kar raha hoon, lekin CrPC ke Chapter 14 mein ek confusion hui hai. Police inquest and magistrate inquiry dono hi investigation ka aisa hi kaam karte hain, par kya difference hai unka? Kya koi specific cases hain jo iska example de sakte hain? Maine papa se poocha, woh kehte hain ki police inquest ka focus mereedh par hai, jabki magistrate inquiry overall case ka investigation karta hai. Par kya isse aisa hi lagta hai ki police inquest se bhi magistrate inquiry ka report mil sakta hai? Koi help karega please, main to yaad kar raha hoon ki AILET mein questions mein kuch to khaas jagah hoga.
