A Typical CMOS Setup

A Typical CMOS Setup

CMOS stands for Complementary Metal Oxide Semiconductor. All PC,s have CMOS chip. In CMOS chip the basic information about computer are recorded permanently, such as date and time, number of installed Floppy Disk, Hard Disk, there configuration, and password etc. The CMOS setup programs are text-based. CMOS setting (such as booting sequence, Date, Time, so on) can be change by using keystrokes to navigate through the information. The Function of CMOS is same as RAM, but to maintain permanent information in CMOS chip a small battery is attached to CMOS chip called CMOS battery.
