How can a flash drive store information without power?
In: Technology
From a very very simple standpoint, a flash drive stores data by flipping switches inside of the device. Off equals zero, on equals 1. Since all data is stored in zeros and ones, we don’t need any thing more complicated. Once the switches are set, the flash drive can be removed from whatever device, and put on the counter and the switches never move.
Same thing happens in your house. Lets say you are sitting at home and you have the light switch on in the kitchen, living room, and one of the bedrooms. The power goes out in your house. A few hours later, the power comes back on, and those lights turn back on. Why? it’s because those switches are still in the on position. They didn’t automatically turn off because the power went off.
