Cards in this deck (20)
- 14GL (Fourth Generation Language)A language that requires little programming knowledge. Can query, manipulate and report on data.
- 2AlgorithmA sequence of instructions designed to perform a particular task. It is a design for a program.
- 3AppletA small program written in java that runs within a web page. Applets are machine independent.
- 4Application LanguageA programming language that is built into a package such as a word processor and can be used to control it.
- 5AssemblerA piece of software that converts assembly language into machine language.
- 6Assembly LanguageA language where each machine code instruction is represented by a mnemonic to make it easier for humans to understand.
- 7BNFBackus Naur Form - A language for defining the syntax of a programming language.
- 8CompilerA piece of software tat converts a high level language into machine language.
- 9Declarative LanguagesLanguages where the programming concentrates on the objectives rather than on the method of solution. Programs consist of facts and rules. Prolog for example.
- 10Dedicated KeyA key or button on a device that caries out just a single function. E.g. record button on a video camera.
- 11DisassemblyConverting a machine code program back to assembly code.
- 12Event Driven LanguageA programming system where components (such as buttons) wait for a users action and then trigger some response rater than going through a predefined sequence.
- 13Flow ChartA diagram that shows the design of an algorithm.
- 14Global VariableA variable that can be assessed from any part of the program.
- 15High Level LanguageA language that allows instructions to be given to the computer without considering the details of the hardware.
- 16Inference EnginePart of the software of an expert system that is responsible for deducing the answer from the facts and rules.
- 17InterpreterA piece of software that converts a high level language into machine language during execution.
- 18Lexical AnalysisThe breaking down of a text file into individual words.
- 19Linkage editorSoftware that will join code from library routines and from code written in a different language into a single executable program.
- 20LoaderPart of the OS that transfers an executable program from disc into memory ready for execution. The OS decides on the address to be used.
