String

string

In programming, a contiguous set of alphanumeric characters that does not contain numbers used for calculations. Names, addresses and error messages are examples of strings. Contrast with numeric data.

1. In a stair, an inclined board which supports the end of the steps; also called a stringer.

2. In a lattice roof truss, a horizontal tie.

3. A stringcourse. Also called stringer, stringboard, or face string. For specific types, see closed string, face string, finish string, open string, outer string, rough string, stair string.

(programming)

string - A sequence of data values, usually bytes, which usually stand for characters (a "character string"). The mapping between values and characters is determined by the character set which is itself specified implcitly or explicitly by the environment in which the string is being interpreted. The most common character set is ASCII but, since the late 1990s, there has been increased interest in larger character sets such as Unicode where each character is represented by more than eight bits. Most programming languages consider strings (e.g. "124:shabooya:\n", "hello world") basically distinct from numbers which are typically stored in fixed-length binary or floating-point representation. A bit string is a sequence of bits.

String 

(1) In vibration theory, a string is a thin, flexible, tightly stretched fiber whose density is uniformly distributed along its length. When the string is excited by, for example, being struck or plucked, it begins executing vibrational motions, in which all parts of the string are displaced in the transverse direction. Any vibration of a string can be represented as the sum of natural harmonic vibrations of the string. The frequencies f of these harmonic vibrations depend on the length l of the string, the cross-sectional area S, the tension Q, the density ρ of the string material, and the conditions of attachment of the ends of the string. For a string fastened to rigid supports, the frequency of the nth harmonic is

where n is a whole number. The displacement distribution at the initial moment—that is, the means by which the string is excited—determines the spectrum of the excited natural vibrations. A string is the simplest distributed-constant vibrational system and is often used to illustrate the oscillations of more complex mechanical, acoustic, and electrical systems.

(2) In music, a string is the source of sound vibrations in a number of musical instruments. The timbre of the sound of a string is determined by the vibrational mode of the string—that is, by the spectrum of the excited natural vibrations. In antiquity, strings were made from tree bark, plant fibers, and animal hairs (primarily horsehairs). In modern musical instruments, steel strings are used for the most part; gut strings, silk strings, and strings made from synthetic fibers (nylon) are used less often. To obtain low tones when the length of the string is limited, the string is made in the form of a thin fiber around which one or two layers of soft metal wire are wound.

Strings are also used in some electroacoustical devices.
