In the realm of computing, the term “execution” refers to the process by which a ordinateur[2] carries out instructions. This process begins with the creation of programs in source code, which is then compiled into an executable file. This file is loaded into the computer’s memory by the operating system and then run from its entry point until it either terminates normally or crashes. The execution process takes place in a specific context, often within multitasking operating systems, and utilizes resources such as run-time libraries. During execution, the computer follows the fetch-decode-execute cycle, and different programming languages manage potential errors in unique ways. Execution also involves a runtime system that provides an environment for the program to operate in and manages application memory and variable access. Some execution processes may involve interpreters, which execute programs directly without translation[1], or virtual machines, which emulate the functions of a physical computer.
Execution à ordinateur and software engineering is the process by which a ordinateur ou virtual machine interpret and acts on the instructions of a computer program. Each instruction of a program is a description of a particular action which must be carried out, in order for a specific problem to be solved. Execution involves repeatedly following a "fetch–decode–execute" cycle for each instruction done by control unit. As the executing machine follows the instructions, specific effects are produced in accordance with the semantics of those instructions.
Programs for a computer may be executed in a batch process without human interaction or a user may type commands in an interactive session of an interpreter. In this case, the "commands" are simply program instructions, whose execution is chained together.
Le terme run is used almost synonymously. A related meaning of both "to run" and "to execute" refers to the specific action of a user starting (or launching ou invoking) a program, as in "Please run the application."
