FFT Simple question

Hi!
I want to know that what does the term "fft bins" exactly mean?. I have searched for it but could not understand it exactly. That if for a discrete signal x(n) we take an N point fft, then FFT spectrum will have N frequency bins. Is it right or wrong. Please correct me if I am wrong.
Thanks in advance.
Regards,
Muhammad Awais

yes u r exactly right, but keep in mind that there are N/2 frequencies as the next half are the exact replicas of the the first
