Basic knowledge of number systems and logic gates

सवाल

Which syllabus does this Computer Organization & Architecture course follow?

It follows the AKTU (Lucknow) MCA syllabus for Semester 1. If your own university's syllabus differs, the centre follows your university's syllabus and unit order.

Is this subject very numerical?

Partly. Booth multiplication, floating-point representation, pipeline speed-up and cache mapping questions are practised step by step in class.

How are students tested at the centre?

Unit-wise MCQ tests, previous AKTU question papers and a final mock paper are given before the semester exam.

Do I need an electronics background?

No. Number systems and logic gates are revised in the first classes.
