Instructions:
1. Students are requested not to submit incomplete and rough like assignments, which results the same as non-submission and hence not allowed to sit for the Assignment Test and therefore their assignment mark for the same will be entered ZERO.
2. The Assignment should be written strictly on A4 sheet, in which the Cover Page and Assembly Language related answers should be in printed form. However, Timing Diagram related answers should be strictly by hand written.
3. It is mandatory to write the question of every answer too.
4. Submission after the deadline is strictly rejected.
| Earning: Approval pending. |
