Computer practice question for SSC. Select an option to check your answer, read the explanation and continue practicing.
The speed of the Central Processing Unit (CPU) is measured in ________, which represents a CPU cycle.
Correct Answerसही उत्तर
B. Hertz (Hz)B. हर्ट्ज़ (Hz)
Explanationव्याख्या
The correct answer according to the source is Hertz (Hz).
The book states that the speed of the Central Processing Unit (CPU) is measured in Hertz, which represents a CPU cycle.
Therefore the direct source-supported association is: CPU Speed — Hertz (Hz) — CPU Cycle.
Gigabyte, Terabyte and Kilobyte are distractors and belong to data-storage measurement terminology rather than the CPU-speed unit required by this question.
This distinction is particularly useful because the surrounding computer questions also discuss storage sizes such as MB and GB.
Students should not confuse units of storage capacity with the unit used by the source for CPU speed.
The source does not discuss kilohertz, megahertz, gigahertz, clock multipliers, cores, instructions per cycle or performance benchmarking.
Therefore those technical details have not been added as source-derived information.
The question's phrase 'which represents a CPU cycle' is the main conceptual clue for Hertz.
A reverse question may ask: Hertz is used to measure what in a computer?
Based on this entry, it is used for CPU speed.
Quick revision: CPU Speed = Hertz (Hz); GB
TB
KB = not the required CPU-speed unit in this PYQ.
Therefore option (b), Hertz, is correct.
स्रोत के अनुसार सही उत्तर Hertz (Hz) है। Book बताती है कि Central Processing Unit अर्थात CPU की speed को Hertz में measure किया जाता है और Hertz CPU cycle को represent करता है। इसलिए direct source-supported association है: CPU Speed — Hertz (Hz) — CPU Cycle। Gigabyte, Terabyte और Kilobyte distractors हैं और इस question में CPU speed की बजाय storage-measurement terms के रूप में दिए गए हैं। यह distinction बहुत important है क्योंकि nearby computer questions में MB और GB जैसे storage units भी पूछे गए हैं। Students storage capacity और CPU speed units को confuse न करें। Source kilohertz, megahertz, gigahertz, clock multipliers, number of cores, instructions per cycle या benchmarking की technical details नहीं देती। इसलिए outside facts add नहीं किए गए हैं। Question में 'represents a CPU cycle' phrase Hertz identify करने का strong clue है। Reverse question हो सकता है: Computer में Hertz किस चीज की speed measure करने के लिए use किया जाता है? Source के अनुसार CPU। Quick revision: CPU Speed = Hertz (Hz); GB/TB/KB = इस PYQ में सही CPU-speed units नहीं हैं। इसलिए विकल्प (b), Hertz, सही उत्तर है।
