What does the term "pipeline" refer to in computer architecture?
A. Concurrent execution of multiple instructions
B. A sequence of logic gates
C. Data flow between CPU and RAM
D. A type of CPU cooler
Answer: Option A
Solution(By Examveda Team)
Option A: Concurrent execution of multiple instructionsThis option is correct. In computer architecture, a pipeline refers to a technique where multiple stages of an instruction execution process are overlapped, allowing multiple instructions to be processed concurrently. This improves the throughput of instructions.
Option B: A sequence of logic gates
A pipeline is not a sequence of logic gates. Logic gates are fundamental building blocks of digital circuits that perform Boolean operations.
Option C: Data flow between CPU and RAM
Data flow between CPU and RAM is related to memory access and data transfer operations, not specifically to the concept of a pipeline.
Option D: A type of CPU cooler
A pipeline is not related to CPU cooling. CPU cooling refers to methods and devices used to dissipate heat from a CPU to prevent overheating.
Conclusion:
Among the options given, Option A: Concurrent execution of multiple instructions correctly describes what a pipeline refers to in computer architecture. It allows for efficient and parallel execution of instructions by breaking down the instruction execution process into stages that can overlap.
