Processing Quiz

What is the main advantage of parallel processing over serial processing?

• Higher accuracy in computations

• Increased speed by dividing tasks across multiple processors

• Lower power consumption

• Simpler programming models

Which category in Flynn's Taxonomy refers to simple, single-core, sequential processing, common in older PCs?

• Single Instruction, Multiple Data (SIMD)

• Single Instruction, Single Data (SISD)

• Multiple Instruction, Single Data (MISD)

• Multiple Instruction, Multiple Data (MIMD)

In which of the following scenarios is serial processing typically more efficient than parallel processing?

• Tasks that are independent and can be executed simultaneously

• Large datasets requiring simultaneous analysis

• Tasks that need to be executed sequentially with dependencies between them

• High-performance computing applications

What is the key distinction between pipelining and parallel processing in computer architecture?

• Pipelining involves executing multiple tasks simultaneously, while parallel processing breaks a single task into smaller sub-tasks.

• Pipelining overlaps the execution of different stages of an instruction, while parallel processing involves executing multiple instructions simultaneously across different processors.

• They are synonyms

• Pipelining is used only in multicore processors, while parallel processing can be used in both single-core and multicore processors.

What type of architecture, according to Flynn's Taxonomy, would a modern multicore PC use?

• Multiple Instruction, Single Data (MISD)

• Single Instruction, Single Data (SISD)

• Single Instruction, Multiple Data (SIMD)

• Multiple Instruction, Multiple Data (MIMD)

Instruction throughput refers to the number of instructions a processor can complete per unit of time (clock cycle or second)

• True

• False

What does concurrency do in computer systems?

• Reduce the number of processors required

• Execute multiple tasks at exactly the same time

• Manage the execution of multiple tasks through multitasking

• Simplify software development

According to Flynn's Taxonomy, which of the following most likely describes a system which systematically shades the images in a video?

• Single Instruction, Multiple Data (SIMD)

• Multiple Instruction, Single Data (MISD)

• Multiple Instruction, Multiple Data (MIMD)

• Single Instruction, Single Data (SISD)

Which of the following best describes a cluster computing system?

• A connected group of independent computers working together as a single system

• A multicore CPU

• A group of nodes with shared local memory, but unequal access times to the memory.

• A single powerful computer optimized for vector processing

What is a key difference between a thread and a process?

• Threads run independently, while processes share resources like memory and CPU time

• Threads are heavier than processes in terms of resource allocation

• A process cannot have multiple threads, while a thread can have multiple processes

• Threads share the same memory space within a process, while each process its own memory space
