Question

CMOS technology is widely used in fabricating:

• A. Magnetic storage devices
• B. Optical fibers
• C. Integrated circuits
• D. Electromechanical systems

Hint:

Think CMOS? Think chips! It's what powers your processors and memory.

Answer 1

The Correct Option is C

CMOS (Complementary Metal-Oxide-Semiconductor) technology is the backbone of modern digital electronics. It is most commonly used in the fabrication of integrated circuits (ICs), including:

• Microprocessors,
• Memory chips (e.g., RAM),
• Digital logic circuits.

CMOS offers advantages like:

• Low static power consumption,
• High noise immunity,
• High density of logic functions.

Why the other options are incorrect:

• (A) Magnetic storage uses ferromagnetic materials, not CMOS.
• (B) Optical fibers involve glass or polymer materials for light transmission, unrelated to CMOS.
• (D) Electromechanical systems (e.g., motors, actuators) use mechanical and electrical components, not CMOS.

Thus, CMOS is specifically used in building digital integrated circuits.
