A way of increasing a computer’s capabilities by adding hardware that performs tasks that are not part of the basic system. Expansion is usually achieved by plugging printed circuit boards (expansion boards) into openings (expansion slots) inside the computer. See also expansion board, expansion slot, open architecture (definition 2), PC Card, PCMCIA slot.
ETYM Latin expansio: cf. French expansion.
In physics, the increase in size of a constant mass of substance caused by, for example, increasing its temperature (thermal expansion) or its internal pressure. The expansivity, or coefficient of thermal expansion, of a material is its expansion (per unit volume, area, or length) per degree rise in temperature.
In mechanics, expansion refers to the increase in volume of steam in the cylinder of a steam engine after cutoff, or of gas in the cylinder of an internal-combustion engine after explosion. See also Charles's law.
