ELI5: Why does turning an electronic device off and on again often fix most of the problems?

A lot of issues with stuff not working is because the RAM (or some other temporary memory) is storing some sort of issue. When you try to do something where the computer has to look at a previously saved value there is a chance the value was saved incorrectly in temporary memory. So when the computer goes back to check that value it throws an error stuff stops working.

Restarting reset all the temporary memory (sometimes you have to take the battery out to fully reset the RAM) and clears that incorrect value.
