Default Why do digital cameras need shutters?

I hope this isn't a silly question. Is it impossible or too
expensive to turn the sensor on and off or something instead of a
mechanical shutter? Just wondering.


It's possible, but slow and inaccurate. It is found on some cheap
(phone) cameras.

Thanks

How can it be inaccurate? Isn't there a processor clock that could time
"shutter speed"? Just wondering and stubborn, too.
