Dictionaries and Google are your friend. Cis is a prefix that comes from the Latin for "on the same side". In chemistry it's used when two atoms are on the same side of a molecule. When speaking of gender it refers to people whose gender identity aligns with(is "on the same side")with their biological sex at birth. If you were born a biological woman and that's how you identify (whether you are sexually attracted to men, women, everyone or no one) you are cisgender, a cisgender woman.
