Computer Science
Memory elements are contiguous if adjacent and apparently connected (but they may, in fact, be disconnected). A computer file or other data stored on a mass storage system, particularly hard disk-based, is said to be contiguous—sometimes, ungrammatically, to be composed of one fragment—if the file data is in one continuous region without intervening extraneous data. A non-contiguous file is said to be fragmented, and can usually be defragmented with a software utility.

Famous quotes containing the words computer and/or science:
“What, then, is the basic difference between today’s computer and an intelligent being? It is that the computer can be made to see but not to perceive. What matters here is not that the computer is without consciousness but that thus far it is incapable of the spontaneous grasp of pattern—a capacity essential to perception and intelligence.”
—Rudolf Arnheim (b. 1904)
“Every known fact in natural science was divined by the presentiment of somebody, before it was actually verified.”
—Ralph Waldo Emerson (1803–1882)
