CMOS (Complementary Metal-Oxide-Semiconductor) uses a small battery to keep the real-time clock (RTC) running even when the computer is powered off. This allows the system to maintain the correct time and date settings, which are stored in the CMOS memory. The battery ensures continuity, making sure your time settings remain accurate as the CMOS chip retains this crucial data.

FAQs & Answers

  1. What is CMOS technology? CMOS stands for Complementary Metal-Oxide-Semiconductor, a technology used in integrated circuits, including those that keep track of time.
  2. How does the battery in CMOS work? The battery provides power to the CMOS chip to keep the real-time clock running even when the computer is turned off.
  3. Why is a real-time clock important? A real-time clock keeps accurate time and date settings, essential for scheduling and timestamps in systems and applications.
  4. Can a CMOS battery be replaced? Yes, CMOS batteries can typically be replaced in most computer systems to restore timekeeping functionality when it fails.
