Runtime

In computer science, the qualifier run time, run-time, runtime, or execution time refers to the period while a computer program is actually executed ("run") in a computer, from beginning to termination. It may also mean the program's running time, the duration of that period. The term is often used in contrast to other phases of program development and use, such as compile-time, link time, load time, etc.. Thus, for example, a "run-time error" is... more

In computer science, the qualifier run time, run-time, runtime, or execution time refers to the period while a computer program is actually executed ("run") in a computer, from beginning to termination. It may also mean the program's running time, the duration of that period. The term is often used in contrast to other phases of program development and use, such as compile-time, link time, load time, etc.. Thus, for example, a "run-time error" is detected only during the execution of the program, whereas a "compile-time error" is detected by the compiler before the program is started. Type checking, storage allocation, and even code generation and code optimization may be done at compile-time or at run-time, depending on the language and compiler. The term runtime as a noun can also refer to a program's run-time environment, the collection of software service that are available to it during its execution. These services may be provided by the operating system, or by a run-time system,... less
