Questions

Which syllabus does the Computer Networks course follow?

It follows the AKTU (Dr. A.P.J. Abdul Kalam Technical University, Lucknow) B.Tech syllabus for Computer Networks. If your own university's syllabus differs, the centre follows your university syllabus.

Will this help in the university examination?

Yes. Teaching is unit-wise as per the AKTU scheme, with previous-year question practice, MCQ tests and doubt sessions before the semester exam.

Is subnetting practised?

Yes. IPv4 subnetting, CIDR, CRC, Hamming code and channel capacity numericals are practised in every batch.
