Falsetto is usually a term used with male singers. Since guys voice are about an octave lower than female voice (even when speaking, not just singing). Therefore in order to sing really high notes, the man has to "switch" into his falsetto. It's easier for girls to do this because we have to sing high usually (unless we're really low altos). The simplest way to explain it, is that it's almost like singing through your head. The sound just comes out airy in a sense and not heavy like from your chest.

falsetto ( false) is a term which we have inherited form the old Italian masters from the 16 and 1700s. It has to do specifically with the change that happens in men's voices when they switch over form their full sound to that light high, little kid sound. It seems to very popular nowadays, but it's actually very old.
Women do have a falsetto voice. It's generally known as whistle register, because that's what it sounds like- a thin high whistle. Mariah Carey used to be able to do this with great effect. Some women get to it very easily, some never reach that altitude. that's ok, too. Another term is "head voice" but there differences of opinion what that means, so ask carefully when someone mentions this term, just to avoid misunderstandings.

It means to use your false voice it is above your normal singing range.
