Which factor is NOT characteristic of CMOS technology?

• A. Requires less electricity
• B. Holds data longer when powered off
• C. Produces more heat compared to older technologies
• D. Is slower than previous technologies

Answer: (C)

In CMOS (Complementary Metal-Oxide-Semiconductor) technology, one of its defining features is that it operates with low power consumption. This characteristic is important in a variety of applications, especially in battery-powered devices where energy efficiency is crucial. The assertion that CMOS produces more heat compared to older technologies is inaccurate; in fact, CMOS technology is known for generating significantly less heat, as its power consumption is primarily dynamic, existing only during switching events rather than continuously, which further enhances its efficiency and longevity. Additionally, CMOS technology is capable of retaining data longer when powered off, due to the nature of its storage cells that can maintain their state without a constant power supply. It is also generally faster than many older technologies, such as bipolar junction transistors, making it suitable for high-performance applications. Therefore, the statement about CMOS producing more heat directly contradicts the recognized traits of this technology.
