Quiz on Computer Organization and Architecture

What is parallelism in computing?

• Reducing the number of processors

• Using a single processor for all tasks

• Executing two or more operations at the same time

• Executing operations sequentially

Answer explanation

Parallelism in computing refers to executing two or more operations at the same time, allowing for more efficient processing and faster execution of tasks, unlike sequential execution which processes one operation at a time.

Which of the following is NOT an application of parallelism?

• Numeric weather prediction

• Genetic engineering

• Text editing

• Artificial intelligence

Answer explanation

Text editing primarily involves sequential operations and does not benefit significantly from parallelism, unlike numeric weather prediction, genetic engineering, and artificial intelligence, which can leverage parallel processing for efficiency.

What does Flynn's classification primarily distinguish?

• Memory types

• Instruction and data streams

• Types of processors

• Operating systems

Answer explanation

Flynn's classification primarily distinguishes between instruction and data streams, categorizing computer architectures based on how they handle these streams, such as SISD, SIMD, MISD, and MIMD.

What is the main goal of hardware parallelism?

• To simplify programming

• To enhance user interface

• To reduce power consumption

• To increase processing speed

Answer explanation

The main goal of hardware parallelism is to increase processing speed by allowing multiple operations to be executed simultaneously, thereby improving overall performance.

Which type of parallelism focuses on the control and data dependence of programs?

• Instruction Level Parallelism

• Software Parallelism

• Hardware Parallelism

• Data Level Parallelism

Answer explanation

Software Parallelism focuses on managing control and data dependencies in programs, allowing for efficient execution by identifying independent tasks that can run concurrently.

In which category of Flynn's classification does a single instruction operate on multiple data streams?

• MIMD

• SIMD

• SISD

• MISD

Answer explanation

In Flynn's classification, SIMD (Single Instruction, Multiple Data) allows a single instruction to process multiple data streams simultaneously, making it the correct choice for this question.

What is the ARM architecture primarily known for?

• 8-bit processing

• 16-bit processing

• 64-bit processing

• 32-bit processing

Answer explanation

The ARM architecture is primarily known for its 32-bit processing capabilities, which have been widely used in various applications, including mobile devices and embedded systems.

Which ARM mode is used for handling high priority interrupts?

• User mode

• FIQ mode

• IRQ mode

• Supervisor mode

Answer explanation

FIQ mode (Fast Interrupt Request) is specifically designed for handling high priority interrupts in ARM architecture, allowing for quicker response times compared to IRQ mode, which is used for standard interrupts.

What does the term 'ILP' stand for?

• Instruction Level Parallelism

• Integrated Logic Processing

• Interconnected Logic Paths

• Instruction Load Performance

Answer explanation

The term 'ILP' stands for 'Instruction Level Parallelism', which refers to the ability of a processor to execute multiple instructions simultaneously. This is crucial for improving performance in modern computing architectures.

Which of the following is a characteristic of MIMD architecture?

• Single data stream

• Deterministic execution

• Multiple instruction streams

• Single instruction stream

Answer explanation

MIMD (Multiple Instruction, Multiple Data) architecture is characterized by multiple instruction streams operating on multiple data streams simultaneously, making 'Multiple instruction streams' the correct choice.
