A run-time system (also called runtime system or just runtime) is a collection of software designed to support the execution of computer programs written in some computer language. The run-time system may provide software services such as subroutines and libraries for common operations, implementation of programming language commands, type checking, debugging, and even code generation and code optimization.

  • A run-time system (also called runtime system or just runtime) is a collection of software designed to support the execution of computer programs written in some computer language. The run-time system may provide software services such as subroutines and libraries for common operations, implementation of programming language commands, type checking, debugging, and even code generation and code optimization. Some services of the run-time system are often accessible to the programmer through an application programming interface; but some services may be inaccessible. A run-time system relieves programmers from the burden of writing code for mundane tasks such as drawing text on the screen or making an Internet connection. It also provides an abstraction layer that hides the complexity or variations in the services offered by the operating system. In the limit, the run-time system may be a P-code machine or virtual machine, that hides even the processor's instruction set. This is the approach followed by many interpreted languages such as Lisp and Awk, and some languages like Java that are meant to be compiled into some machine-independent pseudo-code. This arrangement greatly simplifies the task of language implementation and its adaptation to different machines, and allows sophisticated language features such as reflection (computing). It also allows the same program to be executed on any machine without recompilation, a feature that has become very important since after the diffusion of the World Wide Web.
  • Run-time system (o runtime system) è il termine con cui in informatica si designa quel software che fornisce i servizi necessari all'esecuzione di un programma, pur non facendo parte in senso stretto del sistema operativo. Esempi di runtime system sono: il software generato dal compilatore per la gestione dello stack la libreria software per la gestione della memoria (es. malloc) il codice che gestisce il caricamento dinamico e il linking il codice di debugging generato in compilazione o in esecuzione il codice di gestione dei thread di livello applicativo Anche gli interpreti di codice e le macchine virtuali possono essere considerati runtime system, mentre servizi attivi in processi concorrenti sono considerati come middleware.
