Show answer & explanation
Correct answer: A
Concept
An acronym is correctly expanded only when its letters map, in order, to the established words used for that technology.
For computing terms, the expansion can be cross-checked against the device or fabrication principle the acronym names.
Application
Compare each printed pair with the established expansion and its technical meaning.
Acronym | Established expansion | Technical cue |
|---|---|---|
CMOS | Complementary Metal-Oxide-Semiconductor | Uses complementary p-channel and n-channel MOS transistor networks. |
DRAM | Dynamic Random-Access Memory | Stores charge in cells that require periodic refresh. |
MICR | Magnetic Ink Character Recognition/Reader | Reads characters printed with magnetizable ink, especially on bank documents. |
VLSI | Very-Large-Scale Integration | Integrates a very large number of components on one chip. |
Contrast
DRAM — Dynamic Random Access Memory aligns with volatile memory cells that must be refreshed.
MICR — Magnetic Ink Character Reader names equipment that reads magnetically printed characters.
VLSI — Very Large Scale Integration names a high-density integrated-circuit fabrication scale.
Cross-check
The initial letters of Dynamic Random Access Memory, Magnetic Ink Character Reader, and Very Large Scale Integration reproduce their acronyms. For CMOS, the standard first word is “Complementary,” so “Consistent Metal-Oxide Semiconductor” does not reproduce the established expansion.
Therefore, the incorrectly matched pair is CMOS — Consistent Metal-Oxide Semiconductor.
