what is cmos in computer
CMOS is an on-board, battery powered semiconductor chip inside computers that stores information. This information ranges from the system time and date to system hardware settings for your computer. The picture shows an example of the most common CMOS coin cell battery used to power the CMOS memory.he standard lifetime of a CMOS battery is around 10 Years. However, this can vary depending on the use and environment in which the computer resides. If the battery fails, the system settings, date, and time will not be saved when the computer is turned off until it has been replaced.
CMOS, short for Complementary Metal Oxide Semiconductor, is a low-power, low-heat semiconductor technology used in contemporary microchips, especially useful for battery-powered devices.The specific technology is explained in detail on the CMOS Wikipedia page.MOS, short for Complementary Metal Oxide Semiconductor, is a low-power, low-heat semiconductor technology used in contemporary microchips, especially useful for battery-powered devices.
