Given below are two statements:
Statement I: ALU stands for Arithmetic Logic Unit Statement II: UPS stands for Uniform Power Source
In light of the above statements, choose the correct answer from the options given below:
- A.
Both Statement I and Statement II are true
- B.
Both Statement I and Statement II are false
- C.
Statement I is correct but Statement II is false
- D.
Statement I is incorrect but Statement II is true
Show answer & explanation
Correct answer: C
Concept
This is an acronym-expansion check from computer fundamentals: an abbreviation is correct only when each letter maps to the established full form of the term. Verify a statement letter by letter against the standard expansion, not by how plausible the words sound.
Application
ALU expands to Arithmetic Logic Unit — the CPU sub-unit that carries out arithmetic operations (add, subtract) and logic operations (AND, OR, XOR, NOT). This expansion is standard, so the first statement holds.
UPS expands to Uninterruptible Power Supply — a battery-backed device that supplies near-instantaneous power during a mains failure or fluctuation. 'Uniform Power Source' is not the accepted expansion, so the second statement is wrong.
Result
The Arithmetic Logic Unit reading is accurate while the Uniform Power Source reading misnames UPS; therefore the statement asserting ALU correct and UPS incorrect is the right choice.
