? ? ? ? ?
1. (a) discuss about different buses such as internal, external, backplane, I/O, system,
address, data, synchronous and asynchronous. [10]
(b) Distinguish ranging from high level and low level languages? elaborate the require-
ments for a good programming language? [6]
2. Design a circuit to increment, decrement, complement and clear a four bit register
using RS flip-flops. discuss the control logic. [16]
3. (a) Differentiate ranging from microprogramming and nanoprogramming. [8]
(b) Hardwired control unit is faster than microprogammed control unit. Justify
this statement. [8]
4. (a) How many bits are needed to store the outcome addition, subtraction, multipli-
cation and division of 2 n-bit unsigned numbers. Prove. [8]
(b) What is overflow and underflow? What is the reason? If the computer is
considered as infinite system do we still have these issues. [8]
