A spreadsheet's concatenate ("&") function is used to assemble a complex text string—in this example, XML code for an SVG "circle" element. In formal language theory and computer programming, string concatenation is the operation of joining character strings end-to-end. For example, the concatenation of "snow" and "ball" is "snowball".
Concatenation theory, also called string theory, character-string theory, or theoretical syntax, studies character strings over finite alphabets of characters, signs, symbols, or marks. String theory is foundational for formal linguistics , computer science, logic, and metamathematics especially proof theory. [ 1 ]
In computer science, in the area of formal language theory, frequent use is made of a variety of string functions; however, the notation used is different from that used for computer programming, and some commonly used functions in the theoretical realm are rarely used when programming. This article defines some of these basic terms.
Also simply application or app. Computer software designed to perform a group of coordinated functions, tasks, or activities for the benefit of the user. Common examples of applications include word processors, spreadsheets, accounting applications, web browsers, media players, aeronautical flight simulators, console games, and photo editors. This contrasts with system software, which is ...
Concatenation: Typically used in computer science, | | is said to represent the value resulting from appending the digits of y to the end of x. 5. D KL ( P ∥ Q ) {\displaystyle {\displaystyle D_{\text{KL}}(P\parallel Q)}} , denotes a statistical distance or measure of how one probability distribution P is different from a second, reference ...
Concatenation is a computer programming operation that joins strings together. Concatenation may also refer to: Concatenation (architecture), an architectural composition; Concatenation of paths, a construction in topology; Non-RAID drive architectures § Concatenation (SPAN, BIG)
The different base addresses for color vs. monochrome modes makes it possible for an EGA to be used simultaneously with a monochrome graphics card in the same computer, or for an EGA in MDA text mode to be used simultaneously with a CGA in the same computer. EGA's native graphics modes are planar, as opposed to the interleaved CGA and Hercules ...
VGA section on the motherboard in IBM PS/55. The color palette random access memory (RAM) and its corresponding digital-to-analog converter (DAC) were integrated into one chip (the RAMDAC) and the cathode-ray tube controller was integrated into a main VGA chip, which eliminated several other chips in previous graphics adapters, so VGA only additionally required external video RAM and timing ...
