A measure of how well a computer, service, or application can grow to meet increasing performance demands. For server clusters, it is the ability to incrementally add one or more systems to an existing cluster when the overall load of the cluster exceeds its capabilities. See also server cluster.

Of or relating to the characteristic of a piece of hardware or software or a network that makes it possible for it to expand—or shrink—to meet future needs and circumstances. For example, a scalable network allows the network administrator to add many additional nodes without the need to redesign the basic system.
Capable of being scaled; possible to scale

Any font that can be scaled to produce characters in varying sizes. Examples of scalable fonts are screen fonts in a graphical user interface, stroke fonts (such as Courier) and outline fonts common to most PostScript printers, TrueType fonts, and the method for screen font definition used in Macintosh System 7. In contrast, most text-based interfaces and printing devices (such as daisy-wheel printers) offer text in only one size. See also outline font, PostScript font, screen font, stroke font, TrueType.
Font that can be used at any size and any resolution, on a screen or hard-copy device, such as a laser printer or image setter. Scalable fonts are always outline fonts.

Multiprocessing architectures in which additional processors and additional users can easily be added without excessive increases in complexity and loss of performance. Acronym: SPP.

Escalade

Scalade.

1. Estimation of the amount of lumber in a log.
2. The act of scaling in weight or quantity or dimension.

Of or relating to a directionless magnitude

A factor, coefficient, or variable consisting of a single value (as opposed to a record, an array, or some other complex data structure). Compare vector.
A variable quantity that cannot be resolved into components. Like a ladder; denotable by a number.

A data type defined as having a predictable and enumerable sequence of values that can be compared for greater-than/less-than relationships. Scalar data types include integers, characters, user-defined enumerated data types, and (in most implementations) Boolean values. Some debate exists as to whether or not floating-point numbers can be considered a scalar data type; although they can be ordered, enumeration is often questionable because of rounding and conversion errors. See also Boolean expression, enumerated data type, floating-point number.

A field of scalars.

A diagonal matrix in which all of the diagonal elements are equal.
