In virtual memory systems, demand paging is a type of swapping in which pages of data are not copied from disk to RAM until they are needed. In contrast, some virtual memory systems use anticipatory paging, in which the operating system attempts to anticipate which data will be needed next and copies it to RAM before it is actually required.
To separate two or more channels previously multiplexed. Demultiplexing is the reverse of multiplexing.
A synthetic, three-dimensional macromolecule formed using a nanoscale fabrication process. A dendrimer is built up from a monomer, with new branches added in steps until a tree-like structure is created (dendrimer comes from the Greek dendra, meaning tree). A dendrimer is technically a polymer. In computer applications, early research suggests that dendrimers can be used […]

How tightly information is packed together on a storage medium (tape or disk). A higher density means that data are closer together, so the medium can hold more information. Floppy disks can be single-density, double-density, high-density, or extra-high-density. To use a double-density, high-density, or extra-high-density disk, you must have a disk drive that supports the […]
(adj.) Used typically in reference to a computer language to mean a command or statement in the language that is going to be made invalid or obsolete in future versions.
