Software Programming : Computer Architecture QUESTIONS AND ANSWERS :: part1 : 6 to 10

Following Software Programming language Entrance Multiple choice objective type questions and answers will help you in Software Programming 2015 examinations :

 6.The registers found in the processor unit are Operational registers Memory registers Storage registers Binary registers Temporary registers. ANSWER : 1 Operational registers Explanation : : Registers found in processor are called operational registers and in memory unit are called storage registers.
 7.Given the characteristic table of a JK flip-flop, find the missing output value. J K Q(t+1) 0 0 Q(t) 0 1 0 #1 0 1 #1 1 --- Q(t) Q�(t+1) 1 Q�(t) Q(t+1). ANSWER : 4 Q�(t) Explanation : : The next state is a complement state.
 8.The sum of -6 and -13 using 2�s complement addition is, 11100011 11110011 11001100 11101101 11100001. ANSWER : 4 11101101 Explanation : : 2�s complement of -6 = 11111010
 9.What is Q, when S = 1 and R = 1 for SR flip-flop? No Change Clear to 0 Set to 1 Complement of previous output Indeterminate. ANSWER : 5 Indeterminate. Explanation : : When R = 1 and S = 1, race will always end with Master Latch in the logic 1 state, but this will not be certain with real components.
 10.The bulk of the binary information in a digital computer is stored in memory, but all computations are done in Timing Control Memory Registers Processor Registers Program Control Secondary Memory. ANSWER : 3 Processor Registers Explanation : : The operation part of an instruction code specifies the operation to be performed. This operation must be executed on some data stored in memory and/or processor registers. An instruction code, therefore, must specify not only the operation, but also the register or memory words where the operands are to be found, as well as the register or memory words where the result is to be stored. For this reason, the bulk of binary information in a digital computer is stored in memory, but all computations are done in Processor Registers.
