I had to explain this to a friend recently.
Computers work on binary, which means the only states they really understand are ‘on’ and ‘off’.
And that, my friends, is why so many computer problems can be solved with ‘Try turning it off and on again’.
And software is nothing more than getting a sequence of 1’s and 0’s in the correct order.
Indeed – how many possible order can there be, after all? 🙂
