college university ke liye nahi padh rahe to playlist or videos ki starting mai bolte kyu ho ki bahut useful hone vala hai interview ke liye , competitive exams ke liye or college university exams ke liye ?
Brother the content and explanation is nice .. I'm a south indian and know a bit of Hindi.... ...Kindly focus on the international students as there are not many channels talking about CS and tech.. next time try English
😂bro you will find many content in english search them. varun sir will teach in hindi beacuse it is easy to understand in hindi or as indian you should learn our mother tongue ( hindi )
Sir ,we are watching the full playlist because of our college exams so requesting you to focus on the college students also.

DFD elements:
- Data Store (data base) represented by two parallel lines
- Process - represented by a circle
- External entity - represented by a rectangle
- Data flows - represented by arrows
Rules of DFD:
Data can flow from
- External entity to process
- Process to process
- Process to Data Store
Data cannot flow from
- External entity to External entity
- Data Store to data Store
- External entity to data store
