Correct Answerसही उत्तर
D. AccessD. एक्सेस
Explanationव्याख्या
The correct answer is Access.
According to the source, DASD refers to a Direct-access storage device, so the letter 'A' stands for Access.
The book describes a Direct-access storage device as a secondary storage device in which each physical record has a discrete location and a unique address.
It further states that DASD includes hard disk, magnetic drums and optical discs.
Therefore the complete source-supported revision chain is: DASD — Direct-access Storage Device — A = Access — Secondary Storage Device — each physical record has a discrete location — unique address — examples include Hard Disk, Magnetic Drums and Optical Discs.
Around, Accessible and Arithmetic are distractors.
The source does not provide additional details about access methods, data-transfer speeds, interfaces or historical classification.
Therefore those details have not been added.
Students should remember that 'direct access' refers, in the source's wording, to each record having its own location and unique address.
Quick revision: DASD = Direct-access Storage Device; A = Access; examples given = Hard Disk, Magnetic Drums, Optical Discs.
Therefore option (d) is correct.
सही उत्तर Access है। स्रोत के अनुसार DASD का अर्थ Direct-access Storage Device है, इसलिए इसमें 'A' = Access है। Book Direct-access storage device को secondary storage device बताती है जिसमें प्रत्येक physical record की discrete location और unique address होती है। Source DASD के examples के रूप में Hard Disk, Magnetic Drums और Optical Discs देती है। इसलिए complete source-supported revision chain है: DASD — Direct-access Storage Device — A = Access — Secondary Storage — प्रत्येक Physical Record की अलग Location — Unique Address — Examples: Hard Disk, Magnetic Drums, Optical Discs। Around, Accessible और Arithmetic distractors हैं। Source access methods, speed, interfaces या historical classification की additional details नहीं देती। इसलिए outside information add नहीं की गई है। Quick revision: DASD = Direct-access Storage Device; A = Access। इसलिए विकल्प (d), Access, सही उत्तर है।
