When you delete stuff from your phone (pictures, videos etc.) where does all that data go?
In: Technology
Imagine computer memory as a bunch of switches, either up or down, on or off. The switches themselves go nowhere, they just get flipped on and off in different combinations to mean different things. For example, if you have just two switches, two positions of binary, if they’re both off (00), this can represent the number 0. If the left is off but the right is on (01) then this can represent the number 1. If the left one is on but the right one is off (10), this can represent the number 2. And finally if they’re both on (11) then this can represent the number 3. Of course, we need to represent numbers a lot higher than 3, so you basically have -a lot- of these nano switches to be able to represent very large numbers, and then those numbers can be used to represent other things, like letters, colors, etc.
