Who it is for

Diploma Computer Science & Engineering students of Semester 3 (BTEUP)
Diploma IT / Electronics students who need a refresher on computer organisation
Students preparing for BTEUP semester exams and lateral-entry B.Tech tests

What you need

Basic knowledge of number systems and digital logic gates (Semester 1-2 Digital Electronics)

Questions

Which syllabus does this course follow?

It follows the BTEUP Diploma Computer Science & Engineering Semester 3 syllabus. If your board or college syllabus differs, the centre teaches as per your own syllabus.

Is this subject mostly theory or numericals?

Mostly theory, with short numericals on cache mapping, memory addressing and pipeline speed-up that are regularly asked in exams.

Do I need programming knowledge?

No. Only basic digital electronics and number systems are needed.

Will there be tests?

Yes. Unit-wise MCQ tests and a final model paper are given before the semester exam.
