Question: 1 / 690

What role does the CMOS battery play in a computer?

It powers the CPU.

It stores user settings and system configuration.

The CMOS battery is crucial in a computer as it powers the Complementary Metal-Oxide-Semiconductor (CMOS) chip that stores user settings and system configuration data. This includes information such as the system clock settings, hardware configurations, and BIOS settings. When the computer is turned off, the CMOS battery allows this data to be retained, ensuring that the system can recall these settings each time it boots up.

If the CMOS battery fails or is removed, the settings will be lost, which may lead to issues such as incorrect date and time or difficulty in starting up the system due to misconfigured hardware settings. The other roles mentioned do not pertain to the function of the CMOS battery; the battery's sole purpose is to maintain the data stored in CMOS, making it an essential component for a functional system configuration.
