The floppy drive and CD drive are often referred to as drives with removable media or removable drives for short because you can remove whatever disk is currently in the drive and replace it with another Your computer's hard disk can store as much information as tens of thousands of floppy disks so don't worry about running out of space on your hard disk any time soon As a rule you want to store everything you create or download on your hard disk Use the floppy disks and CDs to send copies of files through the mail or to make backup copies of important items There's too much "stuff" on your computer's hard disk to use it all at the same time Hardware implies permanence and invariability"045 +Software or programming can easily be varied You can put an entirely new program in the hardware and make it create an entirely new experience for the user<>?
