Interpreters convert each statement into machine language, execute it, and move on to the next statement. This stands in contrast to compiled languages, where the source code is transformed into machine code and then executed directly by the host CPU. In this process, the interpreter takes source code written in a programming language and directly executes it, one instruction at a time. What is an Interpreter?Īn interpreter is another type of computer program that also translates a high-level language into a low-level one, but it does so during the actual execution of the program. This makes the compiled program a bit more portable, but requires a bytecode interpreter on every target system. Some compilers compile not to CPU-specific machine instructions but to bytecode, a kind of artificial machine code for a fictitious machine. Although a compiled program lacks human readability as it is written in architecture-specific machine language, it delivers enhanced performance due to the extensive and time-consuming optimizations performed during compilation. This compiled binary includes all necessary resources, except for system libraries, and executes efficiently since it contains native code optimized for the CPU of the target machine. It generates a binary executable in the native format of the target machine, ready to execute without any additional preparation or processing. A compiler is a computer program responsible for translating source code written in a programming language into a different computer language.
