—A storage device composed of a rigid platter or 
platters that can be magnetically coded with data. Hard 
disks hold much more information than some external 
media and are used for long-term storage of applications 
and data. The primary (or only) hard disk in a computer is 
usually fixed, but some computers have secondary hard 
disks that are removable.

saves to the internal storage drive the current state of 
your work, including all open files and applications, 
when you turn the computer off. When you turn on the 
computer again, your work is returned to the same state 
it was when the computer was turned off. See also 
Sleep, Suspend.
hot swapping
—The ability to add or remove devices from a 
computer while the computer is running and have the 
operating system automatically recognize the change.
