Software development processIn software engineering, a software development process is a process of planning and managing software development. It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management. It is also known as a software development life cycle (SDLC). The methodology may include the pre-definition of specific deliverables and artifacts that are created and completed by a project team to develop or maintain an application.
Programmation informatiquevignette|Liste d'instructions sur le Commodore 64 La programmation, appelée aussi codage dans le domaine informatique, désigne l'ensemble des activités qui permettent l'écriture des programmes informatiques. C'est une étape importante du développement de logiciels (voire de matériel). L'écriture d'un programme se fait dans un langage de programmation. Un logiciel est un ensemble de programmes (qui peuvent être écrits dans des langages de programmation différents) destiné à la réalisation de certaines tâches par un (ou plusieurs) utilisateurs du logiciel.
Very high-level programming languageA very high-level programming language (VHLL) is a programming language with a very high level of abstraction, used primarily as a professional programmer productivity tool. VHLLs are usually domain-specific languages, limited to a very specific application, purpose, or type of task, and they are often scripting languages (especially extension languages), controlling a specific environment. For this reason, very high-level programming languages are often referred to as goal-oriented programming languages.
Third-generation programming languageA third-generation programming language (3GL) is a high-level computer programming language that tends to be more machine-independent and programmer-friendly than the machine code of the first-generation and assembly languages of the second-generation, while having a less specific focus to the fourth and fifth generations. Examples of common and historical third-generation programming languages are ALGOL, BASIC, C, COBOL, Fortran, Java, and Pascal. 3GLs are much more machine-independent and more programmer-friendly.
Programming language implementationIn computer programming, a programming language implementation is a system for executing computer programs. There are two general approaches to programming language implementation: Interpretation: The program is read as input by an interpreter, which performs the actions written in the program. Compilation: The program is read by a compiler, which translates it into some other language, such as bytecode or machine code. The translated code may either be directly executed by hardware, or serve as input to another interpreter or another compiler.
Ftraceftrace (Function Tracer) is a tracing framework for the Linux kernel. Although its original name, Function Tracer, came from ftrace's ability to record information related to various function calls performed while the kernel is running, ftrace's tracing capabilities cover a much broader range of kernel's internal operations. With its various tracer plugins, ftrace can be targeted at different static tracepoints, such as scheduling events, interrupts, memory-mapped I/O, CPU power state transitions, and operations related to s and virtualization.
Trace (informatique)En informatique, la trace d'un programme est une représentation de l’exécution de ce même programme. Une trace peut-être utilisée pour analyser le comportement du programme : dynamiquement, lors de l’exécution, afin d'optimiser le code généré par la compilation à la volée ; a posteriori, pour analyser ce qu'a fait un programme lors de l’exécution. Une trace peut être générée par une machine virtuelle, grâce à la programmation orientée aspect, ou par instrumentation du code source.
