Computer practice question for SSC. Select an option to check your answer, read the explanation and continue practicing.
Which of the following is a type of memory and is similar to RAM? It is used by computers to move data between the RAM and the CPU.
Correct Answerसही उत्तर
C. CacheC. कैश
Explanationव्याख्या
The correct answer is Cache.
According to the source, Cache Memory is a very high-speed memory used to speed up and synchronise with a high-speed CPU.
The book describes it as an extremely fast memory type acting as a buffer between RAM and CPU.
It holds frequently requested data and instructions so they are immediately available to the CPU when required.
Therefore the complete source-supported revision chain is: Cache Memory — Very High-speed Memory — Buffer between RAM and CPU — Speeds up and Synchronises with CPU — Stores Frequently Requested Data and Instructions — Makes them Immediately Available to CPU.
Hypertext Link, ROM and I Beam are distractors.
This question expands the earlier cache definition in the book, which described cache as temporary storage for frequently accessed data.
Here, its position and function between RAM and CPU are emphasised.
Students should remember both descriptions because exams may ask cache either through the idea of frequently accessed data or as a high-speed buffer between CPU and RAM.
The source does not discuss L1, L2 or L3 cache, size, SRAM implementation or processor architecture.
Therefore those details have not been added.
Quick revision: Cache = High-speed Buffer between RAM and CPU = Frequently Needed Data
Instructions.
Therefore option (c), Cache, is correct.
सही उत्तर Cache है। स्रोत के अनुसार Cache Memory एक very high-speed memory है जिसका उपयोग high-speed CPU के साथ speed-up और synchronization के लिए किया जाता है। Book इसे RAM और CPU के बीच काम करने वाला extremely fast buffer बताती है। यह frequently requested data और instructions को hold करती है ताकि जरूरत पड़ने पर वे CPU को immediately available हों। इसलिए complete source-supported revision chain है: Cache Memory — Very High-speed — Buffer between RAM and CPU — CPU Speed-up/Synchronization — Frequently Requested Data/Instructions — Immediate Availability to CPU। Hypertext Link, ROM और I Beam distractors हैं। Earlier source question में Cache को frequently accessed data के temporary storage के रूप में बताया गया था; यहां उसके RAM और CPU के बीच buffer role को emphasize किया गया है। इसलिए दोनों definitions साथ में याद करना useful है। Source L1, L2, L3 cache, cache size, SRAM implementation या processor architecture की details नहीं देती। इसलिए बाहर की technical information add नहीं की गई है। Quick revision: Cache = High-speed Buffer between RAM and CPU = Frequently Needed Data/Instructions। इसलिए विकल्प (c), Cache, सही उत्तर है।
