A. Cache MemoryA. कैश मेमोरी

Explanationव्याख्या

The correct answer is Cache Memory.
According to the source, Cache Memory is a very high-speed memory used to speed up and synchronise with a high-speed CPU.
It is described as an extremely fast type of memory that functions as a buffer between RAM and CPU.
The source says it stores frequently requested data and instructions so that they are immediately available to the CPU when required.
Therefore the source-supported chain is: Cache Memory — Very High-speed Semiconductor Memory — Speeds up CPU — Buffer between RAM and CPU — Frequently Requested Data and Instructions — Immediate CPU Availability.
Main Memory, Secondary Memory and Primary Memory are distractors.
Q688 essentially reinforces the same explanation given in Q687, but asks the concept from another angle: which memory can speed up the CPU?
The answer remains Cache Memory.
Repetition of the same explanation in consecutive questions suggests that this is an important examination concept.
The source does not discuss cache levels, capacity, implementation technology or comparative latency values.
Therefore those details have not been added.
Quick revision: CPU Speed-up + High-speed Buffer between RAM and CPU = Cache Memory.
Therefore option (a), Cache Memory, is correct.

सही उत्तर Cache Memory है। स्रोत के अनुसार Cache Memory एक very high-speed memory है जो high-speed CPU के साथ speed-up और synchronization के लिए use होती है। Book इसे RAM और CPU के बीच buffer की तरह काम करने वाली extremely fast memory बताती है। यह frequently requested data और instructions store करती है ताकि CPU को आवश्यकता होने पर वे immediately available हों। इसलिए complete source-supported chain है: Cache Memory — Very High-speed Semiconductor Memory — CPU Speed-up — Buffer between RAM and CPU — Frequently Requested Data/Instructions — Immediate Availability। Main Memory, Secondary Memory और Primary Memory distractors हैं। Q688 वास्तव में Q687 की explanation को दूसरे angle से repeat करता है। वहां RAM और CPU के बीच buffer पूछा गया था, यहां CPU को speed up करने वाली memory पूछी गई है। दोनों का answer Cache Memory है। Source cache levels, capacity, technology या latency comparison नहीं देती। इसलिए outside technical details नहीं जोड़ी गई हैं। Quick revision: CPU Speed-up + High-speed Buffer between RAM and CPU = Cache Memory। इसलिए विकल्प (a), Cache Memory, सही उत्तर है।
