computer organization and architecture

1. The speed of supercomputer is measured in ______.
सुपर कंप्यूटर की गति को ______ में मापा जाता है।
A. Floating-point operations per hour
B. Floating-point operations per day
C. Floating-point operations per second
D. Floating-point operations per minute

Correct Answer: C

Explanation (EN): Floating-point operations per second

Explanation (HI): The speed of supercomputer is measured in Floating-Point Operations Per Second. (FLOPS). These measurements help determine the computational power and performance of a supercomputer.

2. A computer based information system is needed: (I) as it is difficult for administrative staff to process data (II) due to rapid growth of information and communication technology (III) due to growing size of organizations which need to process large volume of data (IV) as timely and accurate decisions are to be taken Which of the above statement(s) is/are true?
Computer based information system की आवश्यकता कब होती है?
A. I and II
B. III and IV
C. II and III
D. II and IV

Correct Answer: B

Explanation (EN): III and IV

Explanation (HI): A computer based information system is needed because of growing size of organizations which need to process large volume of data & so large data need timely & accurate decisions. So, the correct choice is (b).

3. Choose a false statement about Von Neumann's stored program computer architecture:
Von Neumann के stored program computer architecture के बारे में असत्य कथन चुनिए।
A. Program and data are stored in same address space in main memory
B. Allow self modifying program
C. Programs and data are stored in secondary memory
D. Set of control signal is same for instruction and data fetch

Correct Answer: C

Explanation (EN): Programs and data are stored in secondary memory

Explanation (HI): (a). Program and data are stored in same address space in main memory is a core feature of Von Neumann's architecture. (b). Allow self modifying programs because both data and Instructions are stored in the same memory, self modifying code is possible. (c). Programs and data are not stored in secondary memory in Von Neumann's architecture, programs and data are stored in main memory (RAM) during execution secondary memory (like a hard disk) is used for long-term storage, but the Von Neumann's model specifically refers to programs being loaded in to main memory for processing. (d). Set of control signal is same for instruction and data fetch since both use the same memory and buses, the control signals are similar when fetching data or instructions. The false statement is (c) Programs and data are stored in secondary memory.

4. The term ____ is used for the larger, more powerful computers other than supercomputers.
Supercomputers के अलावा बड़े और अधिक शक्तिशाली computers के लिए कौन-सा term उपयोग किया जाता है?
A. Minicomputer
B. Supercomputer
C. Mainframe
D. Microcomputer

Correct Answer: C

Explanation (EN): Mainframe

Explanation (HI): A mainframe computer informally called a mainframe or big iron, is a computer used primarily by large organization for critical applications like bulk data processing for tasks such as censuses. Enterprise resource planning and large scale transaction processing.

5. Von Neumann computer architecture is ______.
Von Neumann computer architecture किस प्रकार का है?
A. SISD
B. SIMD
C. MIMD
D. MISD

Correct Answer: A

Explanation (EN): SISD

Explanation (HI): Von-Neumann proposed his computer architecture design in 1945 which was later known as Von-Neumann Architecture. It consisted of a Control Unit, Arithmetic Logical Memory Unit (ALU), Registers and Inputs/Outputs, Von-Neumann architecture is based on the stored program computer concept, where instruction data and program data are stored in the same memory. Von-Neumann computer architecture is SISD. SISD stands for Single Instruction, Single Data.

6. Which of the following is not considered in Booth's algorithm for multiplication?
निम्न में से कौन-सा Booth’s algorithm में multiplication के लिए विचार नहीं किया जाता?
A. Positive multipliers and positive multiplicands
B. Negative multipliers and negative multiplicands
C. Positive multipliers and negative multiplicands
D. All of the above

Correct Answer: D

Explanation (EN): All of the above

Explanation (HI): Booth's algorithm efficiently handles. Both positive and negative multipliers and multiplicands, so all cases are considered.
