Nikon SLR Cameras

Do point and shoot cameras also have limited shutter cycle like DSLR cameras?

I have a Sony DSC-H20 point and shoot camera. What is the maximum number of shutter actuation on this camera (if it has such thing like their DSLR counterparts) like Nikon D3s has 300, 00 cycles, D90 has 100, 000 cycle etc?

Point and shoot cameras do not have shutters like DSLRs. They work by turning the image sensor on and off quickly, like DSLRs do in video mode. Why else do you think you don't hear a shutter clicking open and closed on digital point and shoots?
