capacity

[kə′pas·əd·ē]
(analytical chemistry)
In chromatography, a measurement used in ion-exchange systems to express the adsorption ability of the ion-exchange materials.
(computer science)
(electricity)
(science and technology)
Volume, especially in reference to merchandise or containers thereof.

capacity

2. The volume contained in a vessel.
3. The maximum or minimum water flow obtainable under given conditions (e.g., specified conditions of pressure, temperature, and velocity).

capacity

As it pertains to airports, it is the ability of an airport to handle a given volume of traffic. It is a limit that cannot be exceeded without incurring an operational penalty.

capacity

(communications)
The maximum possible data transfer rate of a communications channel under ideal conditions. The total capacity of a channel may be shared between several independent data streams using some kind of multiplexing, in which case, each stream's data rate may be limited to a fixed fraction of the total capacity.

capacity

With regard to computer and information systems, capacity refers to the storage and transaction processing capability of computer systems, the network and/or the datacenter. See capacity on demand and storage capacity.
