Volatile
(gcide) | Volatile \Vol"a*tile\, a. [F. volatil, L. volatilis, fr. volare
to fly, perhaps akin to velox swift, E. velocity. Cf.
Volley.]
1. Passing through the air on wings, or by the buoyant force
of the atmosphere; flying; having the power to fly. [Obs.]
[1913 Webster]
2. Capable of wasting away, or of easily passing into the
aeriform state; subject to evaporation.
[1913 Webster]
Note: Substances which affect the smell with pungent or
fragrant odors, as musk, hartshorn, and essential oils,
are called volatile substances, because they waste away
on exposure to the atmosphere. Alcohol and ether are
called volatile liquids for a similar reason, and
because they easily pass into the state of vapor on the
application of heat. On the contrary, gold is a fixed
substance, because it does not suffer waste, even when
exposed to the heat of a furnace; and oils are called
fixed when they do not evaporate on simple exposure to
the atmosphere.

volatile storage
(NVS, persistent storage, memory) A term describing
a storage device whose contents are preserved when its power
is off. Storage using magnetic media (e.g. magnetic disks,
magnetic tape or bubble memory) is normally non-volatile
by nature whereas semiconductor memories (static RAM and
especially dynamic RAM) are normally volatile but can be
made into non-volatile storage by having a (rechargable)
battery permanently connected.
Dynamic RAM is particularly volatile since it looses its
data, even if the power is still on, unless it is refreshed.
An acoustic delay line is a (very old) example of a volatile
storage device.
Other examples of non-volatile storage are EEPROM, CD-ROM,
paper tape and punched cards.

is off. Storage using magnetic media (e.g. magnetic disks,
magnetic tape or bubble memory) is normally non-volatile
by nature whereas semiconductor memories (static RAM and
especially dynamic RAM) are normally volatile but can be
made into non-volatile storage by having a (rechargable)
battery permanently connected.
Dynamic RAM is particularly volatile since it looses its
data, even if the power is still on, unless it is refreshed.
An acoustic delay line is a (very old) example of a volatile
storage device.
Other examples of non-volatile storage are EEPROM, CD-ROM,
paper tape and punched cards.

volatile variable
(foldoc) | volatile variable
A variable in a computer program which can be
modified by processes other than the program. For example, a
variable that stores the value of a timer chip (either because
it is located at the address of the hardware device or because
it is updated on interrupts) needs to be volatile to be
useful.
A static variable, on the other hand, maintains its value
until the program changes it or it is no longer needed. In
addition, volatile variables can be held in the stack
whereas static variables are usually stored in a program's
data segment.
