What is memory actually made of physically in a computer?

Question

Like you have a hard drive to store information but what is that information on the hard drive actually made of? Say you load software onto your computer what is actually being put onto the hard drive?

Answer 1

the hard drive disc itself is made of silicon, all the data put on it is a stream of 1's and 0's like what you see on the matrix, yeah, thats actually computer code...and you thought it was just random numbers!

Answer 2

Files are stored in your hard drive, which contains rotatting sectores engaged by a magnet.

When you load your program, it gets loaded into RAM and calls the hard loaded files from your HDD, and temporarily uses them (editing them as the program runs). Editing files in your HDD is impossible, you need freely accessable "moving" memory if you will. HDD are NOT memory, only RAM is.

When you shut down your computer, your files are still in the HD, but your RAM is now 0. Until you reboot your system

Answer 3

In a hard drive there is a thick metal disk called the platter. The platter has magnetic domains that magnetically store memory. The reader hovers above the disk and reads the infomation from the domains.

Now the so called numbers 0 and 1. So if you press a button on your key board say A, the computer wouldnt recognise it as A it would recognise it as 01000001, this is know as Binary Code, for B it would be 01000010 and so on.

Hope this helps.
