Question

How exactly is data stored in storage systems like SSD/HDD/PENDRIVE? I mean how does it works when receiving and sharing Data?

In: Technology

Answer 1

All data on a computer is represented with a bunch of switches that can be turned on or off. The state of these switches are represented with 1s (on) and 0s (off)

When you put enough of these together, it makes something new. So example:

0000 = 0

0001 = 1

0010 = 2

0011 = 3

0100 = 4

Now, after a bunch of those are put together, you can use that large combination to represent something like a picture

So then, if you want to say copy a file, I just copy the placement of those 1s and 0s. The computer tells the HD or SSD to turn on this switch, or off that switch, till it looks like my picture

**Example**: So I have this picture [a (.) Is 1, and (space) is 0]:

And then, with my clean hard drive which is only full of (space)/0s, I just tell the computer to paste the (.)/1s placement.

So the way i copy the placement of these 2 symbols to get a whole picture, is the exact same method a computer holds data, thinks, and sees the world. And to copy this, the computer says to the other computer “here’s the placement to make this image”
