##Save ![Save][3] 
Personally, I am familiar with the floppy discs, and I have used them in the old days, but now, when I see the floppy-disc icon, I don't think of a floppy-disc, I think of the "Save" function.

___

# ![Floppy][1]  Floppy disc
The floppy image is well known symbol for save, and even though new generations don't know what a floppy disc is, they do know that the symbol means "save". 

___

# ![Hard-disc][2] Hard drive
A modern data storage like a hard drive is not so visually recognizable, so it would not be so useful as an icon. It is a piece of hardware that is hidden inside the computer box.

___


# ![Memory storage][4] Memory storage

And now, some computer have started coming without a hard-disc, they come with only large memory storage, using the same technology as we have in memory sticks etc. 

___
![Donut][5]

 And who knows what the future will bring...
