Explanationव्याख्या
The correct answer is Cache.
According to the source, a cache is a region of computer memory where frequently accessed data is stored for rapid access.
The book explains that a cache is a collection of data duplicating original values stored elsewhere or values that were computed earlier.
The reason for using a cache is that retrieving the original data may be expensive because of longer access time, or computing it again may be more costly than reading the cached copy.
The source summarises this by describing cache as a temporary storage area where frequently accessed data can be stored for rapid access.
Therefore the complete source-supported chain is: Cache — temporary storage area — frequently accessed data — rapid access — duplicate of original or previously computed data — useful when fetching or recomputing original data is more expensive.
Cookie, Plug-in and Token are distractors.
This is an important basic-computing concept because students should understand both the purpose and mechanism rather than only memorising the term.
The source does not discuss cache levels such as L1, L2 or L3, processor architecture, cache size or replacement policies.
Therefore such technical details have not been added.
Quick revision: Frequently accessed data + temporary storage + rapid access = Cache.
Therefore option (d), Cache, is correct.
सही उत्तर Cache है। स्रोत के अनुसार cache computer memory का वह region है जहाँ frequently accessed data को rapid access के लिए store किया जाता है। Book explain करती है कि cache ऐसे data की collection हो सकती है जो elsewhere stored original values की duplicate हो या पहले computed data हो। Cache का उपयोग इसलिए useful है क्योंकि original data को fetch करने में longer access time लग सकता है या उसे दोबारा compute करना cache से read करने की तुलना में अधिक costly हो सकता है। Source इसे simple form में temporary storage area भी बताती है जहाँ frequently accessed data rapid access के लिए stored रहता है। इसलिए complete source-supported chain है: Cache — Temporary Storage — Frequently Accessed Data — Rapid Access — Duplicate/Previously Computed Values — Fetching या Recomputing Cost को Reduce करना। Cookie, Plug-in और Token distractors हैं। यह basic computer concept है और केवल term याद करने के बजाय purpose समझना useful है। Source L1, L2, L3 cache, processor architecture, cache size या replacement policies की details नहीं देती। इसलिए advanced technical information outside knowledge से नहीं जोड़ी गई है। Quick revision: Frequently Accessed Data + Temporary Storage + Rapid Access = Cache। इसलिए विकल्प (d), Cache, सही उत्तर है।
