CPC Mein Darrar ka Fark

Ye CPC ka koi bhi student jaante hai ki darrar mein kuchh aisa hai jo unhein confuse karta hai. Ek tere pass hai aur doosra unke pass hai. Ek hai 'knowledge of certain matter' aur doosra hai 'belief or information'. Dono mein kya fark hai exactly? Mere kai dost hai jo kehte hai ki dono ek hi cheez hai par maine padha hai ki dono alag alag hai. Kuchh log kehte hai ki darrar lagana mere man mein hai, koi cheez jaana ki me darrar lag sakta hoon ya nahi. To aap logoon ki kya raai hai? Dono concept ko clearly explain karein.
