Differences Between Section 65B(4) and Order 20 Rule 19 of CPC: Kaunsa Hai Yah?

Yaar samajh nahi aaya, abhi tak main kisi bhi case mein akele nahin hoon jahaan mera answer bhaari ho jayega! Main confusion mein hoon, agar koi evidence digital hai, toh kya hota hai. Sabse pehle, 65B(4) BSA mein likha hai ki agar electronic record ka original format nahin hai toh ek sworn affidavit ka attachment kar sakte hain, lekin iske baad maine Order 20 Rule 19 dekh liya hai jo bhi electronic evidence ka proof dene ke liye electronic certificate ka attachment karna chaahta hai.
