My question is lil funny but Let me ask it. Where does this data go, Which is deleted by us from our computers or phones? I know it is not matter but still ...........
The file is bits. If not right away, then later (when you try to write over the same area of the disk where the file was), those bits will be replaced by other bits - some bits will remain the same, and others will be flipped. It will no longer encode the information that made up your file, once the specific sequence of bits that made up your file no longer exists, then neither does your file. Unless files have a soul, of course.I created a file in MS word. I uploaded it no where. Im deleting it now. Even from my hard drive permanently, Now where it went away?????????????
Yeah, but why does a processor consume electrical power? The goal is information processing. When you store a bit in a processor register, you've created potential with regard to ground. Once that register is shorted to ground (and the bit is cleared), then the circuit is complete, power is "consumed", and the processor has done what we wanted it to do. Of course there is resistive loss as electrons (and holes) move through the semiconductor, by the whole reason for the processor being powered is to read and write bits.What?
Processors get hot because they consumer electrical power, P = I x V.
I don't think we really disagree here.I think you are getting a bit carried away here. You don't have to get involved with reading and writing bits. That is a completely different issue.
The reason a digital circuit consumes power is because when a transistor switches state from on to off or off to on, it needs to move the charge from one place to another. Moving the charge is what takes energy.
