Given below are two statements:
Statement I: Cache memory is volatile memory and is much slower than Random Access Memory (RAM).
Statement II: CDs, DVDs and Magnetic Tapes are all optical media devices.
In the light of the above statements, choose the correct answer from the options given below:
Answer: B. Both Statement I and Statement II are false — ConceptVolatility describes whether memory retains data without power; access speed describes how quickly data can be read or written. A statement joining two…
- A.
Both Statement I and Statement II are true
- B.
Both Statement I and Statement II are false
- C.
Statement I is true but Statement II is false
- D.
Statement I is false but Statement II is true
Show answer & explanation
Correct answer: B
Concept
Volatility describes whether memory retains data without power; access speed describes how quickly data can be read or written. A statement joining two claims with ‘and’ is true only when both claims are true.
Cache and RAM are semiconductor primary memories: both are volatile, but cache is positioned closer to the processor and is faster than main RAM. Storage media are classified by recording mechanism: CDs and DVDs are optical, whereas magnetic tape is magnetic.
Application
Statement I combines a true volatility claim with a false speed comparison, so the full statement is false. Statement II groups magnetic tape with optical discs, so the full statement is false.
Contrast
‘Both Statement I and Statement II are true’ accepts both incorrect composite conclusions.
‘Both Statement I and Statement II are false’ matches the evaluation of the two composite statements.
‘Statement I is true but Statement II is false’ overlooks the incorrect claim that cache is slower than RAM.
‘Statement I is false but Statement II is true’ overlooks the magnetic recording mechanism of tape.
Therefore, both Statement I and Statement II are false.
