RAM VS HARD DISK

The ram definition according to GOOGLE is random-access memory: the most common computer memory which can be used by programs to perform necessary tasks while the computer is on; an integrated circuit memory chip allows information to be stored or accessed in any order and all storage locations are equally accessible .

The Hard Disk definition is a rigid non-removable disk in a computer and the drive that houses it. Hard disks store more data and can be accessed quicker than floppy disks.

Here is some deffernce between these two items.

RAM: Memory

HARD DISK:Storage

RAM:Smaller amount typically 128 MB to 1 GB

HARD DISK:Much larger amount typically 1GB to 750GB

RAM:Temporary storage of files and programs

HARD DISK:Permanent storage of files and programs

RAM:It could get ruined by a spill of something liquid like a coffee or a coke.

HARD DISK:It's safe from spills.

RAM:Loses all the information when the computer turns off.

HARD DISK:Saves all the information when the computer turns off (unless you delete it)

RAM: Disappear when the computer crashes

HARD DISK:Contents remain when the computer crashes

RAM:When you want to use a program, a temporary copy is put into RAM and that's the copy you use .

HARD DISK:Holds the original copy of the program permanently .

RAM:The file you are modifying, plus all the changes you make, are kept here in RAM until
you do a "save"

HARD DISK:When working on a file, the original file is left untouched here in the Hard Drive until you save it ,The save copies the new version of the file that's in RAM onto the Hard Disk
