will not start, no sound at all

I came out one morning to start my car and nothing happened. So I tried to jump.start the car nothing happened. Not a sound.. the car isnt try to crank.over at all.. but the lights. radio and stuff like.that work perfectly fine. I checked the starting relay that is good. And the fuse under the dashboard under.the driver side label starter.. everything seems fine with the battery system. What esle am I missing?.. thank you
