Hey Sumit, Both courses have their own importance in their respective fields as the name suggests Entc is a branch in which students have study the communication-related topics such as signals, waves, Data transfer and various electronic devices whereas in Computer science you have to study about various programming languages computer hardware and software, machine learning, cloud computing and various other computer-related fields and topics.

Both the branches have equal scope for a good student.

Placements are normally high computer science students but that's not an issue as a good student can easily get placed from any of the branches.

Hope this helps.
