Which of the following pairs of acronym and its expanded form is incorrectly matched?

The correct answer is ​CMOS - Consistent Metal - Oxide Semiconductor.

Key Points

• CMOS - Consistent Metal - Oxide Semiconductor:

The correct expansion for CMOS is "Complementary Metal-Oxide-Semiconductor."

CMOS refers to a technology used in constructing integrated circuits, particularly digital logic circuits, where two complementary MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) are used to represent logic states.

Additional Information

• DRAM - Dynamic Random Access Memory

This expansion is accurate. DRAM refers to a type of random-access memory that stores each bit of data in a separate capacitor within an integrated circuit. It requires periodic refreshing to maintain data integrity, hence the term "dynamic."

• MICR - Magnetic Ink Character Recognition

This expansion is correct. MICR technology is used in banking to facilitate the processing of checks. It employs special ink and characters that can be magnetized and read by specialized equipment, aiding in automatic check processing.

• VLSI - Very Large Scale Integration

This expansion is accurate. VLSI refers to the process of integrating a large number of components (such as transistors) into a single chip, enabling the creation of complex electronic circuits with a high level of functionality and performance.
