Process Images
A process image is a copy of its state at a given point in time. It is often used for persistence. A common example is a database management system (DBMS). Most DBMS can store the state of its database or databases to a file before being closed down (see database dump). The DBMS can then be restarted later with the information in the database intact and proceed as though the software had never stopped. Another example would be the hibernate feature of many operating systems. Here, the state of all RAM memory is stored to disk, the computer is brought into an energy saving mode, then later restored to normal operation.
Some emulators provide a facility to save an image of the system being emulated. This is often called a savestate.

Famous quotes containing the words process and/or images:
“If thinking is like perceiving, it must be either a process in which the soul is acted upon by what is capable of being thought, or a process different from but analogous to that. The thinking part of the soul must therefore be, while impassable, capable of receiving the form of an object; that is, must be potentially identical in character with its object without being the object. Mind must be related to what is thinkable, as sense is to what is sensible.”
—Aristotle (384–322 B.C.)
“The romance and mystery is [sic] gone. Computer-processed images have no delicacy, no craftsmanship, no substance, and no soul. No love.”
—Kim Nibblett (b. c. 1969)
