Re: Question Papers Kannur University

Yes I will get the BCA exam paper issued by Kannur University so that you can get idea of paper and I hope you will clear exam easily.


Part A
ans any ten ques..
1. discuss the concept of base of a number system. provide examples. What is the significance of binary number system in designing computer memory?

2. discuss the significance of complements in binary number system. Distinguish ranging from 1's complement and 2's complement.

3. State and prove De-Morgan's theorem.

4. Write short note on BCD number system using the principle of BCD addition, perform 26 + 37

5. Write short note on the concept of universal gates. Why NAND gate is called a universal gate/

6. Write short note on the Min terms and Max terms. What do you mean by SOP and POS?

7. What is a flip flop? Why flip flops are considered to be the building block of computer memory?

8. With the help of a neat diagram, discuss the working of an RS flip flop.

9. discuss the concept of half adders, discuss the need for full adder.

10. What is a register? discuss various methods of data input to registers.

11. Compare and contradict synchronous and asynchronous counters.

12. discuss the concept of parity in data transfer. (3x 10 = 30 marks)
Part B
ans All ques.

13. Convert the subsequent (327.30)10 = ( )2 = ( )8 = ( )16
OR

14. Using the principle of 1's or 2's complement perform
(i) (63)10 – (27)10
(ii) (36)10 – (68)10
(iii) (101101)2 – (10101)2

15 Simplify using K- map (i) Y = S (0,3,7,9,11,13)
m
(ii) Y = S (1,3,6,7,9,15) + S (2,8,12)
m d
OR

16. (i) State and prove distributive property of Boolean Algebra.
(ii) Draw the circuit diagram of XOR gates. How it is implemented using
NAND gates?
(iii) discuss the significance of duality theorem.

17. discuss the working of JK flip flops with a neat diagram. discuss its advantage over RS flip flop.
OR

18. (i) Write short notes on encoders and decoders.
(ii) discuss the working principle of multiplexers.

19. (i) discuss the need for registers. discuss the significance of MAR and MDR
in data storage.
(ii) discuss the organization of RAM by taking 64 K eight bit system as an
example.
OR

20. (i) elaborate the important classification of learn only memories?
(ii) Compare and contradict the working of SRAM and DRAM.

21. discuss the need for data transfer. elaborate the possible errors in data transfer? How hamming codes are useful in detection of errors in data transfer?
OR

22. What do you mean by A to D and D to A converters? discuss A to D converters
in detail with the help of a neat diagram
( 5x nine =45 marks)
